In a good-quality frame, the joints get special attention. They are glued, dowelled, and screwed. The corners are further strengthened by the addition of reinforcing blocks for extra support and strength. Generally speaking, plywood and particleboard frames are inferior, especially if they are held together with staples. Additional layers of plywood can help reinforce the frame, so as you can see, construction matters as much as material. If you must choose a sofa with a plywood frame, make sure it has at least 11 to 13 layers of plywood.
This is another one for design pros and the design risk takers. In large rooms, a backless sofa (or chaise) is perfect for breaking up the room and creating conversation areas.
The third option is web suspension, in which bands of webbing across the seat and back. These are then attached to the frame to make a platform for the cushions. Webbing can be made of either natural or man-made fibers, and if it is used alone doesn’t make for very strong support. In better-quality sofas, it is used with a tensioner that fastens the webbing securely to the frame. The web suspension is the least preferable of the seating support options.
