Consequently, after using the cover needs to be done sanding hardwood floor to give him a normal appearance. Latex rubber (coating on the foam-based) Manufacturing secondary basis of latex rubber – a lengthy process. It consists of two stages – the application and polymerization of the deposited layer. Secondary layer of rubber is applied by spraying a mixture of uniform, thin layer on a primary basis.
Mainly used for this purpose synthetic rubber latex with the addition of a large number of the filler, usually calcium carbonate. The basic condition for enhancing the chemical process Foam is a thermal effect. Observing a certain temperature, the polymerization is carried out, and as a consequence, the formation of foam, a secondary basis. The quality of rubber is defined very simply: the smaller pore size and the more of them per unit volume, the rubber tighter and better. Carpeting on the basis of foam have been popular in the 70's and 80's in Europe. Explanation of this fact can be found by reading the benefits and disadvantages of this type of foundation.
Advantages. Additional sound and heat insulation, the feeling of softness and comfort even at low altitude nap and density padding. Conservation of linear dimensions for wet cleaning. Snug fit carpet to the floor and as a consequence, the lack of lines and wrinkles on the surface.

One of the most simple and reliable mechanisms. Allows you to place it under a seat roomy niche for linen. The mechanism has no moving or rotating parts, and they come out system in the first place. Remember the old "good" Soviet sofas in which the mechanism of transformation was the only? "Click-klyak", and the sofa converts into a bed.
Very often, unfortunately, these sofas pronounced just "click", and "klyak" was obtained from the second or third time. Despite its simplicity, the quality of the mechanism was far from perfect. Now on the market are reliable and quality mechanisms for sofas type "book", not only domestic but also overseas. However, domestic manufacturers practically apply the mechanism of transformation. Perhaps due to the fact that mass production of poor-quality upholstered furniture in the "old good times "has beaten off all the buyer want to buy" books. " "Withdrawable". One of the most popular and reliable mechanisms. Sleeper "rolls out" from under the sofa. This mechanism is important that the part framework, which goes on the top spot, was made of solid wood (pine tree in the movie would push the groove). Even better, if you are using all-metal frame. Pay attention to the material from which produced videos, as well as on their diameter (the more – the better). Faulty or improperly installed can jam the mechanism. Note the smooth operation. "Dolphin". This mechanism is used mainly models for the angular furniture. The front portion extends the method of "lifting the loop," and pulls for an extra seat cushion, which is a component of the bed.
