DIY sofa accordion - drawings and diagrams

Thanks to its compact dimensions and high performance characteristics, a sofa with an accordion mechanism is very popular. This model transforms into a spacious sleeping area, so it is perfect for both living rooms and children's rooms. If necessary, upholstered furniture can be moved from one room to another. Knowing how to assemble a sofa accordion, this will not be difficult. The model has a simple design that every man can handle without much effort.

Sketching and drawings

The drawings and diagrams necessary to make an accordion sofa with your own hands can be found on the Internet, you can substitute the required dimensions, taking into account the free space in the room, the desired length and width of the bed. But first you need to decide on the design. The soft part can rest on a metal frame with lamellas made from a round or rectangular pipe or on a carpentry frame made of timber and fiberboard. To make a metal frame yourself, you will need metal pipes, high-quality lamellas, lath holders for attaching wooden lamellas to the frame, and other fasteners, a pipe bender, and welding. To absorb the load, it is important to correctly calculate the step of fastening the lamellas. Working with carpentry is much easier.

This article describes in detail how to make a sofa with an accordion transformation mechanism on a wooden frame, consisting of the following parts:

• soft part of 3 sections - rear back, front back and seat;
• 2 soft straight armrests;
• a stiffener connecting the sidewalls at the rear;
• bottom drawer on wheels;
• guide for rolling out the drawer.

You can implement your project. When drawing a diagram or sketch, you need to think through the following points:

• the armrests will be hard or soft, straight or complex in shape;
• will the unfolded sofa have a high back-headboard, or just a stiffening rib connecting the armrests;
• Will there be a box under the seat?

Based on the sketches, drawings are constructed, which indicate the dimensions of each structural element. Based on the drawings, details are drawn up - it is calculated what materials and in what quantities will be needed.

Frame replacement

Repair of sofa parts.

Sofa repair involves replacing foam rubber. To do this you will need to remove the upholstery. This work is carried out using furniture foam rubber, the density of which ranges from 35-40 mm. If the spring block breaks through the foam, then the springs are replaced. The burlap is cut to a specific size. It is laid on the block in 2 layers. Foam rubber is placed on top. It is fixed to the frame with staples, and to the burlap with glue. Then a layer of padding polyester is laid. The fabric is stretched and fixed. The furniture is being assembled.

Repairing an accordion sofa involves installing a new frame and transformation mechanism. Initially, the 2nd element is dismantled. The components must be lubricated with machine oil. Springs that are overextended are shortened.

As for frame repair, this process involves replacing cracked or broken structural elements. Their parameters are preliminarily determined. You can buy the product ready-made at a hardware store. Otherwise, the elements are made to order in a carpentry shop. Parts are replaced, tightened and glued. When carrying out this process, it is recommended to pay special attention to the plywood located under the spring block. If it is poorly fixed, then the plywood is secured with nails and glued with PVA. The dismantled elements are assembled.

Sofa repair involves replacing the spring unit. Springs come in 2 types:

• old (with a height of 20 cm, a diameter of 15 cm and a thickness of 5 mm);
• modern (with a height of 12 cm, a diameter of 10 cm and a thickness of 2.2 mm).

The latter system involves the use of spirals. To replace them, you will need to release the spiral lock from one end. The other end is unscrewed. The spring is released from both sides and replaced. The new spiral is installed.

If several damaged elements are detected in the spring block, then a new system will need to be installed.

Otherwise, the remaining spirals will begin to fail.

Materials, accessories, tools

To make a sofa you will need:

• for armrests - timber with a section of 25x50 mm, plywood 10 mm or chipboard 25 mm for the frame, fiberboard (hardboard) for the sides;
• timber and fiberboard for the frame of the soft part;
• boards for the frame of the box, fiberboard for the bottom, plywood for the facade;
• plywood or chipboard for stiffeners;
• guide boards;
• foam;
• furniture fabric, leatherette can be used for the sides;
• transformation mechanism, support hinges, wheel supports;
• self-tapping screws, bolts and nuts, furniture or universal glue.

When ordering a transformation mechanism, you need to pay attention to its purpose:

• for installation on a metal frame;
• for installation on a wooden frame;
• universal.

The height of the transformation mechanism must correspond to the thickness of the mattress; an unsuccessfully selected mechanism will protrude above the plane of the sleeping place.

The tools you will need are a tape measure, a ruler, a pencil, a screwdriver and/or drill, a hammer, a stapler with staples, and scissors. If furniture covers will be stretched over the soft part, you will need a sewing machine.

The main advantages of the accordion sofa

An orthopedic sofa bed accordion has not one or two advantages, but several. Here are the main ones:

• transformation into a double bed with sleeping space up to two meters,

• orthopedic properties (orthopedic mattress follows the natural contours of the body),

• safe and easy to use sofa mechanism,

• metal sofa frame,

• capacious drawers for bed linen (if the sofa model includes an accordion sofa with a drawer),

• a high enough place to sleep,

• ease of care (removable covers for machine wash),

• the ability to choose an individual sofa shape (from a straight sofa to a corner one, etc.),

• There are many ways to place it (for example, in the middle of the room, near a window, near a stained glass window...).

Armrests

The easiest way to make armrests is rectangular in shape; they can be made quite wide. The armrests are completely symmetrical and differ only in the direction of the bolt for assembling the elements. Sequence of work:

1. Assembling a frame from 4 strips of plywood (top, bottom, front, back walls) and 7 vertical beams, the 7th beam is installed closer to the rear wall of the frame, a hole is drilled in it for a bolt. The bolt is immediately installed in place and fixed from the head side.
2. Covering the frame with foam rubber (allowance at the edges of 0.5 cm).
3. Covered with fabric (allowance of at least 5 cm, for a model with drawstrings more).
4. Manufacturing, pasting with foam rubber, covering the sidewalls from fiberboard (a hole for the bolt is immediately drilled in the inner sidewall).
5. Installing the side panels into the body, fixing them with self-tapping screws in the corners.

If tightening is being done, it is convenient to cut holes in the foam rubber using a joker pipe with a pointed edge. Instead of furniture buttons, you can use footrests on a nail, covering them with fabric. The prepared bearings are driven into the holes with a mallet, the fabric in the tightening areas is pre-fixed to the plywood with a stapler.

The accordion sofa will be used for a long time because it has a design that is simple and ingenious. In the event of a breakdown, you can carry out repairs yourself without outside help.

Soft part

1. Using self-tapping screws, a timber frame is assembled (frame and 2-3 transverse stiffeners).
2. The frame is covered with fiberboard on top.
3. Holes for bolts are made in the lower part of the rear backrest; in these places, the beam must be reinforced with plywood overlays 5-10 mm thick.
4. The frames of the rear and front backrests are laid side by side. The bars, which are in contact, are screwed with self-tapping screws from the inside of the frame closer to the corners. The bars are marked and drilled for mounting holes for the hinges that will fasten the backs together.
5. The fiberboard is covered with foam rubber 8-10 mm thick, density 22. You can glue foam rubber of a smaller thickness in several layers.
6. On the sides of the front backrest and seat, holes are marked and drilled for the transformation mechanism.
7. Frames covered with foam rubber are covered with a stapler using padding polyester or batting, upholstery fabric, or furniture covers are sewn and stretched over the soft part.

Box and small parts

The box frame is assembled from 4 boards; the boards are connected to each other using vertical bars, which are installed in the inner corners. The diagonals of the box are measured - they should be the same. A stiffening rib is attached in the middle. The fiberboard bottom is secured with short self-tapping screws. The front and rear rollers are screwed into the corners. Holes for the transformation mechanism are marked on the sides. The front panel is covered with fabric and attached from the inside to the front wall of the drawer.

The 2 guide boards along which the rollers will ride are connected to each other by two transverse boards, the ends of which, after assembly, should reach the middle of the bottom of the armrest. The parallelism of the guides is checked by measuring the diagonals. The rear stiffener is covered with fabric.

Step-by-step instructions for assembling the product

Before starting work, the mechanism support is placed on the frame of the sofa. Convenient to assemble with two people. The frame base consists of chipboard panels and plywood. It is recommended to assemble the structure, taking into account the fact that it is covered with textiles, soft filling, and a sheet of foam rubber. Legs are installed on the bottom side of the frame base. The bottom should be lower than the surface of the second part of the product. Instructions for assembling the sofa for users:

1. Align the holes of the mechanism support and the rear part of the frame. A bolt is inserted from the outside, and a nut is secured from the inside. Place the spring on the rod and secure it with tendrils to the mechanism support and the seat frame.

3. The mechanism is unfolded. A mattress is placed on top of it. The surface of the product on which the Velcro is located is installed on the seat frame, where there are also Velcro.
4. The mattress is laid in such a way that the sticky elements are connected. The distance between it and the plywood should be the same on both sides.
5. Then the remaining Velcro is attached around the perimeter of the mechanism.
6. Take out the upholstery fabric and lay it so that the Velcro on the cover coincides with the slots on the edge of the mattress. Insert the adhesive strips into the slots down under the mattress.
7. Spread the resulting sofa cover over the entire mattress.
8. Velcro connects the cover and the mattress.
9. Remove the washers and nuts from the bolts and insert them into the mechanism supports. Insert washers from the inside and tighten with nuts. After the mattress is secured, proceed to installing the armrests.
10. Align the mounting holes of the armrest with the mounting holes of the transformation mechanism bracket. The holders are secured and inserted into special grooves.
11. After this, the back of the sofa is put on plastic connecting elements that tighten the armrests to each other.
12. Assembly is complete. The sofa is placed in a position where you can reach the lamb and tighten it until it stops.
