I just started sleeping on this mattress and it has a horrible bubble in the middle. This is the cool calming queen mattress. It's a replacement for a different mattress from serta and it only lasted 6 months before the sides started caving in. I will never buy a serta mattress again.

We love our new comfortable firm mattress perfect for side sleepers

Don't have any issues with the bed or service. Customers should know this bed is very firm.

Very comfortable mattress for me. Firm but not too firm. No more back ache.

I asked for an extra firm mattress and yes I got just that. A good night sleep thanks Serts

Comfy good for sleep all night and all day and great texture for restful sleep.?

The mattress is very well made, and more importantly, provides a good night's sleep.

This mattress is firm yet comfortable.

Best mattress!!!!

[This review was collected as part of a promotion.] Some of the best sleep I’ve ever had. This bed is comfortable but still firm. It helps support my back while also helping me get restful sleep! No more aches an pains in the morning.
