Best Mattress Ever!

Firm, but not too firm, felt supported and blissful from the very first night...best sleep I've had in months!

Great support and comfort for us side sleepers

So far our decision to replace our old Serta Icomfort Applause II was a good one. Very supportive, and provides a better night’s sleep.

Perfect Sleeper

This mattress will be “perfect” as soon as my back adjusts to the firmness. I do like the comfiness of the top layer and the mattress is supportive.
