  • Great Mattress for a great price!
    Verified Purchase

    Bought this mattress 2 months ago for my daughter's bed. It's firm but still comfortable (Even when my husband or I need to lay with her). The best part was the price was $XXX cheaper than other websites! What a great deal!

  • Excellent mattress!
    Verified Purchase

    I just got this mattress today and must say that it is 100 times better than my old mattress. I checked the web for mattress prices before I bought this one and it was a lot less than a lot of the other stores. One top of that, they delivered it for free and picked up my old mattress for free. It's a little higher than my last mattress which is a plus. It is on the firm side which is okay, but I do wish that it was a little softer, but I'm not complaining. It's a good deal and a nice mattress. I'm happy I got it.

    My son loves his mattress. He officially has the most comfortable bed in the house. I purchased my mattress from a mattress store and am not satisfied especially since my sons mattress is such better quality purchased from Overstock.

    I bought this mattress set for my Mother who has a bad back, and was surprised at the comfort and quality at such a low cost! It is soft and cushioned nicely on top while being firm at the same time. Mom didn't need to get a foam topper. She's happy and comfortable. Very pleased with the quality of the mattress as well.
