A modern sofa bed is the main piece of furniture in almost every home. For the convenience of users, manufacturers are developing various transformation mechanisms that turn the seats into a comfortable berth. The most popular corner sofa today is a dolphin - a practical, durable product. Before choosing it, you should familiarize yourself with the key characteristics, advantages and disadvantages of this upholstered furniture.

What is a

Dolphin transformation system is the most common sliding mechanism installed in corner sofas. This is a movable metal structure with rigidly fixed guides along which the rollers move, ensuring the movement of the frame. Pulling on a secret loop, you can easily extend the additional section. The platform, as it were, jumps out from under the main seat, which looks like a dolphin jump - hence the name of the mechanism.

Corner sofas are divided into static and mobile views. In the first embodiment, structural elements are rigidly fixed. In mobile samples, the main part and the folding corner can move apart.

The design of the corner sofa dolphin consists of the following elements:

• frame;
• support frame;
• transformation mechanism;
• fasteners;
• seats and back;
• decorative fittings.

The dolphin mechanism is considered the most complex, but at the same time the most reliable and convenient for the quick organization of a daily berth. Such models are compact when folded, and when unfolded they form a wide and even rectangular box. They withstand a large load (up to 400 kg), are slightly deformed, and are durable. In furniture stores you can pick up products of different price ranges and designs.

Disadvantages of sofas with a dolphin system:

• lack of a compartment for storing linen;
• uneven elasticity due to different stiffness of the seat, hidden platform and angular protrusion;
• height differences between components may occur;
• the berth is located rather low;
• the difficulty of moving the rollers of the roll-out platform if the carpet is on the floor.

The designs of modern corner sofas include a linen box under the ottoman.

Materials of manufacture

In the manufacture of sofas with a dolphin transformation mechanism, various materials are used: wood or metal for the frame, filler, upholstery fabric.

Housing

Upholstered furniture is always based on strong and reliable frames. In their manufacture, the best hardwood is used: ash, beech, walnut, oak. Such cases are particularly durable.Pine and birch are cheaper and less quality wood, which makes furniture less expensive, but such structures can crack over time.

Glued beam is used in the manufacture of sidewalls. The quality of the wooden case is determined by a perfectly smooth surface. More affordable - chipboard, MDF, chipboard, plywood, but these materials wear out and deform faster.

Particleboard sofas should be selected with care, as they may contain harmful formaldehydes.

Metal frames also have good technical characteristics. They have high strength, durability, resistant to ignition. However, heavy weight makes them impractical to use.

The transformation mechanism is made of high strength steel. Some design features facilitate the extension and lifting of the platform:

1. Furniture gas lift or hydraulic gas device. The design is made of a piston and a cylinder filled with inert gas, due to which a cushioning effect is created, which ensures smooth operation of the spring. The presence of this element facilitates the lifting of the seat.
2. Synchronizer bar. Evenly distributes the load, not allowing the bedroom place to warp. Fastens with rollers and brackets.
3. Several levels of lifting simplify the procedure of folding and folding the sofa.

With various modifications of the transformation system, the principle of action remains unchanged.

5. Spring unit. Products with a rigid spring block have a complex structure. It is wrapped with soft materials and attached to a wooden frame. Spring mattresses have several advantages: durability, reliability, elasticity, good ventilation and moisture exchange.
6. Coconut tow. Elastic natural material is extracted from coconuts. It has a strong structure, in combination with other fillers it is used to isolate them from hard metal springs. Only high-quality coconut tow from ripe fruits is suitable as a filler.
7. Furniture foam or polyurethane foam. Soft porous foam with high quality performance. It is characterized by strength, density, elasticity, breathability. It is used in the manufacture of upholstered furniture of various brands. Deservedly considered one of the best fillers.
