"It's good, I like it!"

These are the words of the wisest, smartest, and most beautiful person in the world: My Wife. Passes the wife test, passes my test.

Sister bed

My sister seems to be comfortable and sleeps well through the night. No more saggy mattress she wakes up with a smile on her face.

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.

Impressions permanent in less than two weeks

The mattress already has divots or impressions from where we sleep in less than two weeks. We are not overweight.

Perfect!

I was looking for more support something not too hard and not too soft and I settled for the plush and it’s perfect!

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.

Adjustable bed

I like the bed but unhappy that I cannot use my head board and it is difficult to keep the top sheet secured.
