Firm and comfortable

The mattress is very firm, which I at first was unhappy about. However now, after several months, I am very glad I chose it.

So far so good

Have had one night only so far and we are very pleased. Slept very well! Just the right level of firmness for us.

Comfy, supportive, great quality

Our new Serta mattress and box springs are very comfortable and supportive (for my bad back). This mattress is very well made.
