Breaking in just fine - build quality, I suppose, could be better - tufting stitching has already come away from top layer. Still, happy with the purchase and series 2 firm feels supportive and stable.

The mattress does not meet my expectation. For the money i spent on it, i was hoping for more comfortable sleep after having it but it was the opposite. I have back pain more often.

This is an expensive piece of junk. Warped and has a huge indent where we sleep in less than a year! Bought this hoping it would relieve our back pain from our old mattress however it doesn’t seem to be made any better!

I’ve wanted a Beautyrest Black mattress for 12 years. Sit N Sleep did not have a plush pillow top so I’m hoping the medium pillow top will be soft enough for me. I have faith this mattress will last me many happy hours.

[This review was collected as part of a promotion.] We received the Queen firm mattress and it's very comfortable and durable. It provides a lot of back support as well. It's def firm but it also has some cushion to it. I would recommend.

Comfortable from day 1

Nice comfortable sleep

Back pain issues

We have had our mattress for almost a month now and it has been such a great sleep every night since.

First great sleep in years! I didn’t want to get up and couldn’t wait to go back to bed. Great product!
