This is extremely short knees under chin and uncomfortable to sit on. I purchased 12” boards to build a frame for the sofa to sit in and since we had a piece of Timber Tech board that we used for our deck I clad the frame in it. I also purchased a piece of 5” foam and covered it in a black bed sheet which now makes it more comfortable to sit on. When spring comes, I will buy some large pillows to go across the back since the back of the sofa hits right beneath your shoulder blades. I should’ve invested a lot more money and bought a better one.
