After reading almost everyone's review (on most sizes: XL, L, M), I decided to buy Large bags (set of 2). I think my husband is pleased with it. He is a 200+lb guy. On the other hand, I am a small frame women of about 115lb. I am not sure if my weight is not heavy enough for me to make the bag sink enough. As some other reviewers mentioned, I feel like sitting on top of a big blob. It just doesn't sink enough like the pictures, but again, it could be due to my lighter-side weight... I am not sure if taking some foams out will help.Also, as other reviewers mentioned, when I opened up the zipper trying to see if I want to try removing some foams, the pieces of foams looked like regular pieces of sponges, not "memory foam." From the pictures of "Praxis" memory foam, I was expecting pieces of memory foam, so that was my surprise.I also bought two ottoman. With ottoman, you can lay back, put your feet on ottoman, and be comfortable. But without ottoman, again, I just can't sit comfortable enough because it does not sink for me. I would have given 5 stars, but for the fact it is not as comfortable as I hoped for from reading all reviews, I am giving 4 stars.
