Cliff did you get your cushions?
The only advice I have is to make sure that you lay on the cushions as well as sit on them. The feeling is different! I had a friend pick out cushions for me for my
dinette. Great seats - but when turned into a bed - oh my hard as the floor.
Learning from that - for my sofa - I did part foam and part memory foam (mattress topper) and came up with a really good bed.
