For a more accurate choice - determine the scope and frequency of use of the sofa. If people sleep in the living room every night, the “accordion” type is best. Orthopedic bases will help to raise the level of comfort, so check with the purchase whether they are embedded there.
If the sofa is chosen to simply receive guests, then take either a vacancy model or an “eurobook”. As their advantages - quick layout without complicated mechanisms.
For children, the range of sofa is also great, as well as for living rooms. Therefore, try not to be conducted on beautiful wrappers, but judge by the following parameters.
The sofa in the working environment should not be pompous and ornate, but remain comfortable and solid. Often choose products with metal structures, which is very well suited for passageways.
