Snug as a Bug, Lawrence, KS
This mattress is SO comfortable. It's somehow both incredibly soft and incredibly supportive. Delivery was also quick and easy, and they took away our old mattress and topper.
My husband has experienced pretty regular back pain for over a year, and after a few doctor's visits, physical therapy, muscle relaxers, massages, you name it, nothing made a huge difference UNTIL we upgraded our mattress on a whim. Immediate relief. We both sleep so well. It's been a few weeks and I still look forward to laying down every night because it's simply that good. Even the dog seems happier with it.
For reference, I am 5"6', my husband is 6"2' and we are very happy with the standard King.
Absolutely worth the money.
