In order for the transformation mechanism to serve for a long time, the following operating rules must be observed:

The folded mechanism can only contain the mattress supplied with the product. In the folded mechanism, the presence of bedding and foreign objects is not allowed. When transforming the mechanism, do not allow bedding, foreign objects and fingers to get between the moving elements of the mechanism. If unfolding or folding is difficult, check that there are no foreign objects in the hinge joints without using excessive force. It is not recommended to sit or lean on the edges of the mechanism that do not have support: headrest, leg section.

NEW ROLLER

The transformation mechanism “New Roller” is unique among its counterparts: the sofa unfolds from the headboard, thanks to which the pillows do not need to be removed – they go to the bottom of the sofa. Developed by the Belgian company Sedak-meral and, like all other mechanisms of this company, has a high quality of assembly and the material used.

ADVANTAGES:

Does not fit into the sofa and is essentially the basis of the sofa or its frame. It has no analogues in the simplicity of the folding-layout. The ability to screw the back of the sofa at the buyer’s home makes the sofa “walkable” into any doorways. This mechanism can withstand a load of up to 500 kg. You can use a mattress up to 140 mm thick, which significantly expands the number of mattresses allowed for this model of the mechanism.

The steel lattice from which the sleeping place is made occupies 2/3 of its surface and provides a safe and comfortable sleeping place even for people with spinal problems.

“LUKA D30”

As a berth, a double-folded mechanism of transformation of the Russian production “Luka D30” is used. Folded depth 780 mm. The sleeping surface in the places of the greatest load is made of welded mesh, the diameter of the bar is 4 mm. Elastic straps on the leg. The straps also allow you to get a more comfortable seating position in the sofa position. The load is perceived not only by the sofa cushion, but also by the mechanism mattress. The rods are made of 5 mm steel strip. This solution allows you to achieve the highest reliability and durability of this connection. The head part is made as a single load-bearing element, consisting of: a U-shaped arc, a transverse tube with a diameter of 30 mm and a wall thickness of 1.5 mm, interconnected by a welded mesh.

FEATURES:

This mechanism, when unfolded, allows you to get a sleeping place measuring 1620 x 1890 mm. The height of the mechanism when unfolded to the upper edge of the mattress is 410 mm.

“RANUCHCHI”

Italians, furniture trendsetters, are sure: to sit and sleep on different elements of the sofa, because softer filler is required for sitting, and harder filler for healthy sleep. The Ranucci double-fold mechanism is a unique mechanism for daily sleep, the comfort of which is comparable to a full bed. The berth consists of three parts, two of which are the base of the seat before the transformation, and the third, folding, forms the back. The assembled sofas with the Ranucci mechanism occupy a minimum area, because the Ranucci mechanism itself is both a sofa and a sleeping place at the same time, which saves space in the living room.

The mechanism unfolds in one movement, the seat and back cushions do not need to be removed, because they go under the sleeping place. As a result of unfolding, we get an excellent sleeping place, without joints, without level drops (which often happens when various roll-out systems are used). The mattress is made of high-quality polyurethane foam, and the support for it is a welded steel mesh, fixed to the frame of the mechanism with the help of springs (this creates additional comfort).

The frame of the mechanism is made of steel tubes, and the parts of the mechanism itself are made of steel sheet. The simplicity, comfort and reliability of the Ranucci mechanism have been appreciated and chosen for their furniture by such a world-famous hotel chain as Hilton..
