    Memory Foam Tips:
  • Remove from packaging within 72 hours of receipt to maximize memory foam expansion
  • This product arrives tightly packed in a box sized to be portable; once you unwrap it, you can sleep on it the same night, although it may take 48 hours to return fully to its original shape.
  • Memory foam is inherently comfortable and supportive, no matter how firm it feels; similar items can vary in firmness due to the nature of the foam
  • Product is vacuum sealed at the factory for efficient shipping; vacuum sealing sometimes traps odors, but once opened, a few hours of airing will usually remove the odor
  • Due to machine-cutting manufacturing processes, there may be slight variances in the dimensions of this product.

Due to the nature of Memory Foam the firmness level of every item is unique. Please be advised that even similar products may produce different firmness results.

  • decent and comfy

    I purchased two of these for a day bed + trundle and they worked out perfectly. The name brand is actually a bit misleading because it's a mattress made by Sleep Innovations being sold by Serta under the Serta brand (the packing documents make that clear). That said, the mattresses arrived tightly compressed in two big 2'x2'x4' boxes, were easily unpackaged, decompressed, and allowed to air out for a couple days before getting used. There was a strong odor at first, but it dissipated. They are very comfortable mattresses so I'm hoping they stand up well over time. The only negative that comes to mind is that the mattresses do not have reinforced edges so there's not as much support if you're sitting on the edge of the bed. Many mattresses lack this feature until you spend a little more, though, so it's still a great bargain and a simple compromise. Moreover, the lack of edge support actually works out great, possibly better, for popping up the trundle and making a "short" king out of the daybed without having a hard seam between the two mattresses. In all, a great deal and comfortable mattress.

  • light & comfortable

    After a lot of research and seeing a lot of poor quality spring mattresses in the $200-400 range, we bought these for our kids' bunkbeds- I am so glad we did. They are light- so easy to lift onto top bunk, but just as comfortable as the brand name memory foam mattress we have for the grown ups in our house... Our kids are very happy and tell us that they think the bed is really cozy. Since our kids are still little we have put a mattress protector under the sheets, but they don't seem to notice. I have taken a nap on one of the mattresses and founf it to be very very comforatble. The boxes arrived in less than a week (UPS) and we opened them immediately to let them unfold and "off gas", and set them up the next day. Overnight the light smell had dissipated and the mattresses were completely uncurled. We are very very happy with our purchase and will consider these mattresses again- they are not cheap, but much more affordable than Tempurpedic and lighter as well. We think they are worth the price.

  • Nice Product

    I have ordered it for my son's bed. The item was shipped on time and it arrived in good shape. The Box has the Serta label but the original manufacturer is Sleep Innovations. I am very impressed with this product. After sleeping on it, I slept through the night after a very long time without much tossing and turning. It is firm but the Gel component of the mattress makes it very comfortable.

  • Very comfortable

    I have this mattress for couple years now. It is very comfortable and I have gotten compliments from couple occasional guests on how well rested they feel after spending the night.

  • Serta 8-inch memory foam mattress

    The only thing I might've done differently would be to have chosen the 10-inch Serta Memory Foam mattress. I had wanted to be sure my fitted sheets would work well, so chose the 8-inch. A wonderful night's sleep!

    She sleeps great on it, love the packaging

  • Sorry quality. Try to get that back in the box.

    It says a twin size, but under options says Queen. This was the queen sized mattress. This mattress would not lay flat. It says give it some time, but it never did lay flat. 20 months later, the same corner still sits up 2-3 inches, unless you are sitting on it. Now, the mattress is splitting from the top and the bottom along the centerline. It appears that in a few months we will have two halves of a queen mattress. Maybe this had been sitting all folded up in a box for a very long period of time and should not have been sold. DO NOT BUY THIS PRODUCT. Once the foam mattress comes out of the box, you will never get it back in to return. Having bought several of these and being happy before, this poor experience takes all the joy out of an Overstock Memory Foam mattress.

  • Very comfortable

    My five years old son loves this mattress.

  • Great Mattress!

    In 2010 I bought this mattress in a King Size but with a different pillow top. It took about a month for me to get used to sleeping on a memory foam mattress, but my salesman had warned me that was sometimes the case. I love my bed. This twin is superior. It is self-supporting...does not need to be in a frame. It sleeps great. I have a Coolmax Wicking Performance Mattress Pad ( on the bed and it is performing well (no problems with heat build-up). Serta is a reputable company and the mattress comes with a good warranty. I got the mattress on sale and the price was awesome. I did have problems with the first mattress that I ordered (it never arrived) but O took care of me.

    Ordered a memory foam mattress to replace my standard type. I am very pleased, although I've only had it for two weeks. Very comfortable. No noticeable smell.

For the contour beds that have remote control settings they are usually recommended for split mattresses, so each person can choose their own settings. This would work if you do not plan on having 2 settings. It will only work with one setting. overstockcustomercare1 on Jun 11, 2012
