Before you look for drawings, buy the necessary materials, choose which product you want to get and what model you will be able to make. Transformer beds are divided into several varieties.

  • Bed-cabinet - with a lifting device, the bed is pressed against the wall and looks like a simple cabinet. This species is the most popular among the others and is considered one of the mostly practical in small-sized housing. Bed transformer with your own hands this type is easier than other models.

If you are a small specialist and begin the manufacture of a transformer bed with your own hands, stop at a simpler version. As mentioned above, such is a cabinet bed. To start, do either find the drawing of the future product with the necessary parameters, markup of fasteners and connections.

The bed, which, if necessary, can be converted to a wall cabinet

The model bed-cabinet is divided into three main parts, which will first need to create separately and then combine into one. The following are these elements and materials necessary for manufacture.

Manufacturing process

Connection of two parts for a double bed - frame and bedroom

Installation of a bed type transformer consists of two items - the first thing you need to make a frame for a folding mechanism, and then a sleeping place. On the Internet, you can find ready-made dimensions for standard single and double models, but if you need other parameters, they will have to count them yourself. In this excellent assistant will be the program "Furniture Designer".

Attach the frame with the help of the corners on the anchors, if you have walls made of concrete or brick, or screws in case the wooden house

Make rigid fixation of anchor bolts strong metal rack on the wall. It will be needed to strengthen the frame with metal corners. For the base of the frame, take two reliable boards - they perform a carrier function, the average length for standard forms of transformer beds is about two meters. At the edges, at the top and bottom, with the help of glue and self-tapping screws, fix them with a transverse board. Adhesive connection and self-drawing to the finished frame of the trim. Remember - it is necessary that the depth of the box corresponded to the thickness of the bed. So as a result, do not get a box that does not fit the finished product, it is better to make it a few centimeters more.

Mounting cabinet bed frame using bed lift mechanism

Next, you can start mounted a hitch bed. As the basis, take the phaneer corresponding to the necessary parameters. In order to avoid damage and deflection of the material, strengthen it from below by installing four boards along and across the future product. For greater comfort, it is possible to equip the base of the bed with a variety of sides, but remember - the lifting mechanisms should not interfere.

Connected frame and base, with a construction enhanced wooden bar in the middle

The next stage is the fastening of the frame to the wall. For a long period of operation of the finished product, choose only high-quality fasteners. Loops fix the folding part to the frame, and secure her free end with the help of special fasteners - it is thanks to them a bed transformer holds in folded form and suddenly not decompose. If you cover the wooden surface with varnish, it is advisable to do it as long as the folding part is not fixed with the frame.

Last Step - Ready Product Decor

The transformer bed can be supplemented with small lockers, shelves or mirrors, which will give the design of greater functionality. In the versions of modern design, the product can be painted with acrylic paints - the most popular bright colors are in children's rooms. The bedroom can be issued using a combination of several colors and applying patterns. If you do not know how to draw, on the Internet you can find a lot of stencils - print the desired and create a unique design with it.

For more compliance with the wardrobe, the outer side of the product can be issued with the help of invoice, false crossbars and imitation of the handles. You can also create additional niches using mirrors or set additional illumination elements - light bulbs, LEDs.

The ends of the boards place the self-adhesive edge - it can be purchased in any construction store. Attach the edge by the adhesive side to the end, go through it with a hot iron. Next, swipe with a dry cloth, clinging carefully. Exterior cut and stick with sandpaper.

As you can see, the result of the bed of a transformer made by their own hands will turn out nothing worse than the factory, but somewhere even better and will become unique in its kind. The main thing is desire, patient, strict compliance with instructions and the use of quality materials.

Video: Wardrobe bed do it yourself

In any small room, there is always a shortage of free space for the arrangement of various furniture. For example, for the organization of the workplace, a children's corner, for a bedroom living room. And of course, for another bed, which occupies a significant area in any room and requires approaches on two sides of a width of at least 50 cm. Therefore, it is necessary to look for extraordinary furniture and planning solutions for organizing a comfortable living space.

In such a situation, universal furniture, a transformer, which will help combine multiple functions, will come to the rescue, and will decorate the interior, despite the deficiency of the area.

First of all it concerns those rooms in which the bed is installed. In the daytime, it is quickly removed in a niche with the help of the lifting mechanism, lifting the vital space for other purposes (Fig. 1.2).

Instead of a bulky bed, a compact sofa appears, which is actively operating during the daytime (Fig. 2).

The folding double bed is easily converted into a vertical wall, on the reverse (back) side of which you can place several posters or even paintings adorning the interior (Fig. 2).

It is worth reminding that before starting an assembly with your own hands, it is necessary to draw detailed schemes to determine the procedure for assembling furniture, and purchase the necessary building materials for this. In the drawing, you need to specify the size of the bed and the dimensions of the individual elements, the form and dimensions of the additional boxes, as well as the type of mechanism that can be folded, extending, rising and modular.

For the transformation mechanism, it is necessary to use reliable and durable parts that must withstand the daily use and weight of the future design. They also need to be purchased in advance, they are sold in construction supermarkets.

As practice shows, the most rational variant of the transformer is lifting the pipe of the lifting mechanism, the other is on the stand (Fig. 1, 2). In the vertical position, the folding (reference) stand is folded, pressed to the plywood base of the box. For a more convenient and "soft" sleep on such a bed, lamellas between the mattress and plywood can be installed, which will add the sighting of the mattress, and accordingly creates additional comfort.

Interesting the planning option for placing the bed on the floor under the podium (Fig. 3). The floor podium is arranged at an altitude of 45-50 cm from the floor. The framework is mounted under it, on which the floor boards are based on, for example, carpet. On the edge of the podium set the decorative light wall from the plates. Then collect the basis - the box-frame from the boards (this was described and shown in Fig. 1.2).

On the bottom, roller mechanisms are attached to the frame, allowing the most part of the podium bed. The smaller part is used as a sofa, in which inclined pillows perform the backlord features. If necessary, you can completely push the bed under the podium, thereby freeing another part of the space of the room during the daytime.

Among the various options for planning solutions, the transformer-cabinet and a bed in one device attracts. Some apartments have niches that can be successfully used in this design. A wardrobe with a rotary mechanism is placed in a niche. On the one hand, the bed, and on the other - the wardrobe with the shelves. Plus this design is that the shelves and shelves existing on the back side of the bed are always under the same angle to the floor.

What is this constructive solution? In essence, it consists of two main elements: frame-box, which performs the function of the cabinet (Fig. 4) (it is he fills it with a niche). And with him another box, which is a bed.

Thanks to two metal holders, the bed can change their position, leaning out and turning into the bed for sleep. The design is easily rotated around its axis due to the rotor mechanism installed on the floor and on the ceiling. The bed is rising and fixed with special clasps that will keep the design in the assembled form, and the entire unit turns towards the room and is a cabinet with shelves.

By choosing a folded bed with a rotating base, you don't have to release the shelves each time before laying the bed, which is very convenient.

The main requirements for the installation and operation of this furniture are perfectly smooth surfaces of the walls of the walls. When skewed, the design is loosened, and it is also possible to join the mechanisms, weakening the fasteners.

A somewhat unusual is a transforming table, which will be pleased to supplement a small room as a coffee table, for example. It consists of several volume discs (Fig. 5), delivered over another and connected vertical pipe. It does not turn into a full-fledged table, but it becomes larger at the expense of glass surfaces, and also has an additional storage system. All its surfaces are grouped and covered with furniture varnish in several layers.

Note: Cabinet Book with your own hands


The dream of any needlewoman is a cozy workplace, where everything is at hand. Living in a small apartment, not every can afford to distinguish the area under the workshop, where you can arrange the necessary materials and do your favorite craft. My husband is an architect, and solved this problem in his own way, make a wardrobe transformer for me.

In the corner of the room from the side of the window built frame under the podium. To do this, they ordered and installed a welded construction from a metal profile.

The idea was that on top of the construction could be equipped with a workplace, and the retractable bed in the bottom in the niche. Made a step for comfortable lifting on the podium. Then, a thin metal profile was secured throughout the frame and the construction of increased wear resistance laminate wasted (33-34 class).

Taking into account the size of the niche, the bed was made from below and installed roller fastening, with which it easily put forward forward (we use it as a bed) (photo 1), and also moves inside, transforming in a vacation sofa or reception (photo 2)

On the podium collected a wardrobe transformer. The door is attached on the hinges (photo 3) and rolls back on the wheels (photo 4, 5).

Inside the cabinet for its entire length and width fastened the worktop for the workplace. Over it, the P-shaped design was installed shelves with drawers without guides and fasteners, if necessary, they completely come from their offices.

Inside the central niche put a table for a laptop, which can be removed and released an additional place to work.

From the bottom of the tables were placed a tube with drawers for paper and smallest things, and a printer was put on it. LED lamp fired from above (photo 6)

Despite a small niche in the door, it also placed the retractable cobes for the storage of needlewood materials and a free shelf for books, which also installed the lamp (photo 7) from the bottom of the open shelf faded boxes (sold in the store as "galoshnitsa" for shoes). They are conveniently placed paper and felt sheets, foamiran, polyethylene packaging (photo 8)

I am doing needlework now not only with pleasure, but also with comfort!

Constructions are divided into transformers with a horizontal or vertical mechanism. The choice of system affects the dimensions and style of room design. Products rising vertically, most often acquired and functional. Horizontal transformers will fit narrow rooms with low ceilings.

Tools and materials

Before creating a transformer for a small apartment or premises with a larger area, it is recommended to purchase workers and tools. For designs, wood plates are needed: furniture shields, chipboard, pls, etc. Materials are purchased after drafting, the indicator add 10%.

The furniture shield is made by pressing boards, bars without adding synthetic compositions. The material is environmentally friendly, durable, easy to work, but has a high price. More budget and affordable - chipboard (chipboard, LDSP). Boards produce various colors, thickness and density. The strength rate among the composition is less than that of furniture shields. The preferred thickness is about 20 mm.

In the manufacture of a bed-transformer, you will need a set of special tools: drill, screwdriver, electrolovik, perforator, grinding machine, centimeter roulette, construction level, square. There are also pliers, a file, a knife, a set of screwdrivers and so on.

For the design, accessories will be required: a folding mechanism, configmatics, screws and screws of different sizes, furniture corners - standard and reinforced, anchor fasteners, handles, facade decoration elements.

Wardrobe bed do it yourself

Simple and available for self-execution Model combining wardrobe and sleeping bed. The product consists of 3 parts that are created separately and then combined into the design folded. Before making a transforming bed with their own hands, it is necessary to perform the calculations of the size of the model and make a drawing with placed places for fasteners. You can use ready-made schemes or make a plan on your own, designing each item.

The dimensions and shape of the base body for the bed depend on the required functional and the size of the room. An important part of the transformer is a spacious niche under sleeping place. With independent making frame of the cabinet bed, the plates are often chosen (laminated or standard), since the material is unpretentious in processing, is available at cost. You can order the DPE details on the desired parameters from the manufacturer, in which case the edges of the edges of the elements of the edge ribbon will be processed.

MDF plates or chipboard are fixed at the bottom of the base, in the assembled form they serve as a facade of furniture. When designing elements, the interior design is taken into account. Rack and sleeping space combines lifting device. The mechanism transfers heavy loads, so experts advise you to choose high-quality systems. In the manufacture of a wardrobe bed, attention should be paid to the dimensional characteristics of the mattress, the presence of accessories.

Making frame frame

The transforming frame must hide a compact leisure place, so it is performed according to the calculated size and configuration. The design should provide access to a spacious niche for a sleeping bed. When calculating it is important to consider the parameters of the mattress so that the depth of the box coincides with the bed thick. Experts recommend adding 2-3 cm to the desired size.

The material serve simple in the processing of the chipboard plate. Cutting parts are performed from manufacturers to avoid the formation of chips. You can order from specialists and ready to frame that it will simplify installation work, but it will be more expensive than self-fulfillment of the design.

As part of the box, several elements: plinth, the back wall of the cabinet, shelves for the stop. There are typical standards of the dimensional series, but you can perform an individual project - according to the author's design. In this case, accurate independent calculations will be required.

For the framework of the frame, 2 boards are needed, which become supporting in the design. The size of the beams is about 2 m. From above, at the bottom and on the edges of the beams are fixed on the tapping screw and glue. Reliability add transverse boards. Over the finished frame is performed, the materials are fixed with adhesive compositions. The fasteners are performed using self-tapping screws or screws that are placed at a distance of 25 cm. The assembly work is carried out on a flat surface.

Production of folding bed

The next stage is the installation of the folding part of the sleeping bed. The basis protrudes plywood, painted to the required dimensions. To avoid deflection and damage after installation, it is recommended to use 4 boards and add transverse plates. Strengthen sleeping beds extra boards. Additional elements should not prevent the functioning of the lifting system.

When performing a folding unit, competent calculations are needed to avoid box overload. The movable part must facilitate the design. The bed lifting mechanism can be represented by garage veins, solid axes or pin with bearings.

It is important to ensure the lift frame with the mattress and fixing the design vertically without physical effort. This requires spring blocks or counterweight. The lifting mechanism for the transformer bed is not necessary, the systems can be purchased ready.

What do you do with old furniture?

It has long been a video that shows how you can make it from plywood, indispensable for small apartments, furniture - transformer bed table. The idea really liked, but did not come out. This video is:

Agree, a wonderful idea! And quite simple at first glance implementation. Right take and do.

I began to look for additional information about this bed. I also found such a video - the process of creating this bed in Sketchup is recorded here.

I also realized that there are errors in the original video. Moreover, both in the original sizes and when processing the video. The thickness of the washers, the gaps between the details are not taken into account at all. It is also not clear how the installation location is selected, which fixes the horizontal position of the table top in the process of converting furniture from the table to bed and back.

In general, all these questions had to decide again.

A few words about the design. The product consists of two parts. The first part is a frame-frame. By the way, on its basis, it is possible to attach another full-fledged cabinet or a second tier on this product. The second part in turn consists of two parts - the skeleton of the bed and the tabletop of the table. They are connected to each other in such a way that regardless of the position of the bed frame, the table top is always in a horizontal (or almost horizontal) position. Transformation from one state to another occurs with rotation (lifting) frame of bed. When the frame of the bed in a horizontal position - the bed turns out. If you raise it (turn) into the vertical position - the bed is hiding, and the table top rises from the floor level into the working position - the table is obtained.

That's what I did.

Position "bed"

The size of the place under the mattress 1914 * 914 mm. I left this size original. The mattress of 190 * 90cm is suitable for it. Mattresses of such sizes are available in our stores. 7 mm gap around the perimeter can be useful for belts. Whatever the mattress does not fall out with the whole bed - it is worth thinking about the belts.

Bed height - 500mm. Multimito, but not critical. (Although adding to the altitude of the mattress - for someone it can already be inconvenient) In this embodiment, the mattress level will be below 32 mm. If desired, it can be constructively lowering even lower and make a cut in the sidewall that limits the mattress. This will reduce the height of the bed of centimeters by 10 maximum.

In this version as now the maximum mattress thickness is not more than 160mm

In the "Bed" position, the table cover plasters without gaps falls on the floor.

Slightly degraded for a better understanding.

Position - "Table"

Table top height from floor - 768 mm. Quite a normal height for an adult.

Table top depth - 332 mm. This is clearly not enough. Who wants to increase it - there are two ways to increase forward and increase back. The first way is the easiest. Just increase the size of the tabletop details. The second way will require changes to the design of the bed.

Well, even in the width of the workplace pleases))).

It is worth paying attention to the framework of the bed (the detail where the mattress is stacked). Its thickness 20cm. If you do not draw the mattress to lower the height of the bed, then in the position "Table" on the back wall (which is the bottom of the bed) free space appears. It can be used to install the shelves in the form of pockets. Or you can fasten the monitor on the holders to the hospital. This will free on the table top.

Now a few words about the transformation process.

As I already wrote, in the video instructions for the manufacture of beds, the center of the hole for the auxiliary plank and its length was noted correctly. Or I just did not understand. In general, with the specified dimensions and placement of the holes, it is clearly noted.

I had to understand this matter from scratch. I got like that

Recorded a small video - the process of transforming the bed in the table and back in motion.

As you can see, at the bottom and upper point, the countertop is in a horizontal position.

In the transformation process, approximately in the first quarter of the movement, the tabletop position is slightly deviated from the horizontal. About 2-3 degrees. A glass with water will not turn over, but the handle / pencil can easily ride. Well, this is the best thing happened.

What is this program (in which the kinematics of the associated movement was simulated), if I wonder, I will describe in a separate article. So wait for your feedback.

For the manufacture of a metal plate, I looked after a sheet metal 3mm thick. Such a large number of holes and screws (as shown in the video), I think you do not need. It is enough 3 holes and connect not to the screws, but on the screws and nuts. Moreover, one hole for rotation and two for fixation. So it will be clearly more reliable.

By the way, there are ready-made solutions of the mechanisms of transformers table-bed. Patriotic samples cost from about 2000 UAH. Curly (Western) analogues are price times more expensive about 10 thousand UAH. This is if you do not want to "invent the wheel." Well, the design of the bed is completely different there. But we are not looking for light paths ????)))))

Our bed has a mechanism easier. That's just so far there is not enough depreciation system. I look towards gas pistons (approximately the same as in factory solutions). I have no experience with them yet. If someone takes it to help me with the calculation / choice / accommodation of the gas piston (gas elevator) - I will be very grateful.

Here I have got the bed-table table from plywood

Here in the image there is still no buzzing-gaskets between limiting planks and the movable part. But they do not make much weather.

I plan to bring your project to the final drawings with Croy cards. Moreover, both for the CNC machine and for cutting on the usual format machine. Make the specification of all accessories (screws, nuts, hairpins, etc.). True, when it is - I will not say for sure.

You will also need to search and pick up the book locks in a vertical position.

The project bribes relative simplicity of sales and a large hook for modifications.
What are you tell me? Have you wanted to make yourself such a bed?
