  • LOVE IT!!!

    I really wanted a temperpedic mattress, but heard so many horror stories of how the mattress quickly sinks in the middle over time and it makes you very hot at night. So that's when I decided to look into a hybrid between a temperpedic and box spring mattress. I absolutely LOVE this mattress, and you can't beat the price!!! I've had this mattress for 3 years now and it's absolutely amazing. The only con is that since I sleep by myself most of the time, the mattress has lost some firmness in the area where I lay--this still happened even though I make sure to flip my mattress and turn it around every few months. Still, the difference is not very noticeable and I still sleep great. I also love the firmness of the mattress--I wanted a firmer mattress, but still with a soft feel of the temperpedic. That's exactly what I got. And, they even installed it (took apart my old mattress, put it where I wanted it, and setup my new bed) for free!! And they were very fast with doing the setup!

  • Terrible Off Gassing but a good mattress overall

    If you are in any way sensitive to chemicals stay away from this mattress. It really does provide good back support but if anyone had shared that it off gasses a chemical smell for - literally 3 months!- I never would have purchased it. I have allergies and asthma and it was brutal for me to sleep on this thing for the first month and a half. Each morning I would strip the sheets off the bed and open our windows in the bedroom with a fan going when it was freezing out to get the chemical smell out of our room. These sorts of chemicals should not be allowed to be put in our furniture.

  • Perfect Mattress

    This mattress set is perfect. The delivery team did an awesome job and went about as painless as it can get. They took away the old set as promised. I can not believe how much better I sleep now with the new mattress. Also, I used to have back pain in the morning which has gone away. I can not recommend this mattress set to anyone. The price was great and the process went perfectly.

  • This mattress right for us.

    This mattress is exactly what we wanted. It is firm without being hard. It supports the body very well. It is very comfortable. One can sit on the side of the mattress without it collapsing. The cover is good material. We are very happy with this mattress. Thank you.

    I'm so BLESSED and Grateful for this set. I'm the kind of person that will pray on large purchases and let the heaven's above do the rest. And, I've NEVER been let down! The reviews were good , but I think this set is better than I could have ever dreamed... Thank you OVERSTOCK for offering this set at an AMAZING PRICE!! I would have paid over $1000.00 + in a mattress store or warehouse for this type of set. Not to mention, the delivery fee that would have been attached.The delivery was very professional, and within the time frame quoted. And, they cleaned up everything before leaving my house. I could not be happier. Oh, before I forget the firmness is just what I needed for my back!!! MUCH LOVE OVERSTOCK, GLENDA

  • Great mattress set

    This mattress is very comfortable, we got it after discovering I was pregnant with twins. I spent most of my whole first trimester sleeping on it and it is a great investment. Being 28 weeks pregnant with twins I still sleep decently on the mattress set.

  • Good Night Sleep

    Serta Perfect Sleeper Liberation Cushion Firm Queeze-size mattress is a firm bed but with extra cushion that make it not too firm. At first, I couldn't get use to the cushion but after a few nights I got use to it. The cushion provides the extra support that I needed without wrapping up my body like a memory form bed would. The price on Overstock was great and the white glove delivery was excellent. They took the bed all the way up to my 3rd floor apt and there are no elevator. A similar bed like this in Macys would cost me $800. The bed did sit very high with the box spring on my sleigh bed. I'm 5'4 and the bed was to my bottom when standing next to it. Didn't like that at first but I got use to it now. Actually, I kind of like it now because I could get on and off the bed without having to bend over or anything :) I'm very happy with my purchase and I'm getting a good night sleep.

Questions & Answers

  • What does low Profile set mean?

    • Thank you for your interest for the Serta Perfect Sleeper Liberation Cushion Firm Queen-size Mattress and Box Spring Set. The height of a standard box spring is approximately 9 inches. The low profile box spring measures approximately 5 inches. Both offer the same support you need for a good night’s sleep. Low profile box springs are a great option for people who have high bed frames or are purchasing a very tall mattress. I hope this information is helpful.

  • What is the coil count for this mattress?

  • what is the memory foam density per SF?

  • What is the difference in a split foundation and a regular foundation as far as comfort?

  • Can I order without a boxspring?

  • Does it squeak?

    • This item comes new and unused, it should not squeak.
