I am remodeling two bedrooms. Everything new top to bottom. Bought one mattress (not Casper) to see if I liked it. I did like it and kept it but gave it to my daughter who likes a very firm mattress. I read the info on the Wave Hybrid and decided to buy it. (It cost me about a third more.). I really like the Casper Wave Hybrid and the pillows.  I have a hard time falling asleep and staying asleep. I seem to be falling asleep quicker and waking up less often. I recommend the Wave Hybrid. It is very comfortable.
