Great mattress!

I was real nervous about buying this mattress after reading reviews but so glad I did! It’s been great! It’s comfortable, firm but not too firm and sleeping quite well! Very relieved and pleased.

So far so good. I can tell that I am better rested than I was prior to swapping out the cheap amazon mattress I had been sleeping on. Not amazing (I used to have a Casper and that was my favorite), but solid for the price.
