It's been about 2 weeks

So far very happy with this mattress. I love the fact it's got handles all over it which makes moving it around possible.

Great mattress. Hopefully it stays this comfortable. Very happy as of now. Best sleep I’ve gotten in years!

Simmons mattress

This is a very firm mattress but is comfortable and does a great job with back and stomach sleepers.

The most restful sleep in years

We have the Black Series 3 Medium Prime. It surpasses the firm mattress we had previously. No regrets.
