Firm and hefty!

[This review was collected as part of a promotion.] The Perfect SIeeper Quilted Hybrid was aesthetically, a very clean beautiful mattress with quite a bit of thickness and heft, which made setting it up a bit challenging without assistance. The weight does add to the sense of durability and sturdiness. I was pleasantly surprised to find no odor, which is often an issue with newer mattresses. Most notably though, the mattress is quite firm, which is the style I selected. It's exactly as advertised, very firm. There is little cushion or give but provides great support. I would not recommend this mattress if someone wants to "sleep on a cloud" but rather, would be ideal for those needing extra back support. For anyone looking for a firm mattress that feels built to last, this one would be a great choice.

Fantastic support!

This mattress is so comfortable! Perfect amount of softness on the top to support my curves with great firm support beneath. I am just giddy to climb into bed each night. I don't know why I didn't buy a new mattress sooner. I had no idea what I was missing!
