Honestly....Best. Mattress. Ever!!!! I sleep so soundly now. I make everyone lay on it when they come to my house. It is the best sleep I have ever gotten.
Tried different mattresses-too hard, too soft, and my current one-just right Casper Hybrid. My only complaint is the “edge” isn’t quite as stable as it should be. I do wonder about the Wave, however, it’s description does not lead me to believe the mattress edge is different from the Casper.
Just the right firmness for my back and yet soft enough for damaged shoulders! It appears to be well built with strong sides. I expect it to last much longer than the Sleep Number mattress it replaced.
