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.

Nice firm mattress

We replaced a failing mattress with this Serta Hybrid... it nicely firm and supportive, but not overly hard. It sits a little higher up than previous mattresses (maybe due to the matching foundation?) but my tall husband appreciates the extra height.
