Firm and comfortable

Love new mattress. Side sleeper and it is not too firm to cause discomfort. Highly recommend.

Serta

Mattress is very pretty in color and comfortable. I hope it will last at least 10 years.

So far so good!

I've only slept on my new mattress five nights and I really like it already.
