Good mattress

I have only had this mattress since May and there's already dips in it from where my husband and I both lay and we're not big people.

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.
