    I dont think I've ever left a review for any kind of product, however....this was the BEST purchase I've made all year. My husband is the biggest skeptic and believes everything is a ploy to get our money. When I told him I purchased this mattress topper, he said "just throwing your money away, you know its not going to work". WELL WELL WELL, we have BOTH admitted that this is BY FAR THE MOST COMFORTABLE mattress topper I've ever had. I put my nephew down to sleep on the bed, where he would only sleep 1 hour at a time, he slept for 3 hours! I'm a busy person, who runs off very minimal sleep maybe 3-4 hours a night, and this has made a BIG difference in my sleeping pattern. I'm now thinking about purchasing this mattress topper for the pull out bed in the living room! I'm sure our guests will appreciate it. I'm sleeping more soundly, more comfortably, not waking up tossing and turning ever 30 mins, and my husband and I are both noticing the differene in our energy levels. We now wake up refreshed and READY. Where as we had to literally push each other off the bed to get up for work! GREAT GREAT GREAT! I can't rave enough :-)

  • WOW !!!

    I can't believe I didn't try this years ago. I broke my back in an automobile accident, and as you can geuss I'll be suffering with back and neck pain for the rest of my life. The memory foam lets me sleep and relax with no pain. Also an added benifit is the relief from pressure points, thanks Overstock. Not to mention my wife loves it so much we bought 2 more for the children's beds.

  • Great Buy

    This was the best money i ever spent on bedding. It made a very hard mattress quite comfortable saving me money as I did not have to buy a new mattress. The cost was also very reasonable compared to others. I was initially leary as some other reviewers said this was not memory foam, but it most definately is. It does bounce back. I had no smell issues either. I aired it out as directed on the package. I had none of the problems some of the other reviews mentioned. I would recommend this for anyone that wants to make a hard bed cushier.

  • Comfortable and worth the price

    I bought this for my own mattress after having a mattress topper for a futon. I went for this brand because of the more affordable price and I am very pleased with how comfortable it is. Definitely worth the money.

    • Did the color match the color displayed onsite? Yes
    • How is the quality of the product? good quality
    • Did the description onsite accurately describe the product? yes

  • Squishy

    Took a little while to get used to, but I sleep great now, and its very comfortable! Feels a little sweaty at first, but I adjusted to it. Like sleeping on a giant marshmallow. Warning: does not taste like marshmallow. I need a new one though because my dog decided he would try to dig through it. He was succesfull.

  • This is a very great product

    This is a very comfortable memory foam mattress. SInce I purchased this over a month ago, I sleep so soundly and wake up in the morning not wanting to get out of the bed. I give this "TWO THUMBS UP!"


    iceman73 from Yonkers, NY, Dec 17, 2014

  • Great product at a graet price

    Bought my first bed. Went WAY too firm thinking it would help me get up for work in the morning. So, I decided to look into fairly inexpensive memory foam, which for the most part is like finding a unicorn. Was wary about this product at first, a lot of people said it's not thick enough, not as good as advertised. I've been sleeping great so far. It's not the best memory foam I've ever laid on, but very good, very comfortable, and quite affordable. No "toxic" smell or anything. I let it air out for a few hours before putting it on the bed. FYI I'm 6' and 190 lbs, since weight distribution can affect comfort with regard to sleep items.


    GroovyMcGiblets from Houston, TX, Dec 15, 2014

  • Good value

    The 3" thickness refers to the spikes on the foam, not the to the actual base thickness... that takes away from the full effect of the topper. Otherwise ok for its price.


    Prinxie from Murfreesboro, TN, Dec 11, 2014

  • huge difference!

    This gave my ten-year old mattress a new lease on life! It slides a bit and makes changing sheets a bit more challenging, but well worth it. I sleep much better and now have to force my kids out of the bed more often!

Can this mattress be repacked once it has been opened in order to take it to a different location? shlycola42 on Jan 2, 2014
Subscribe to Answers
Answer This Question

Yes, absolutely. The best way to do this is to fold it in half lengthwise, then into quarters, and roll it up while compressing it as tightly as possible. Have a very sturdy plastic or fabric bag nearby, to put it into. It may be helpful to put a flat sheet under it, to help facilitate getting it into the bag, so it slides in, instead of getting stuck, because it's foam. I moved two of these recently, and it worked perfectly. When you unroll it, it will take a little while for it to plump back up to its original loft, just as it does when you first receive it. kaminmi on Jan 4, 2014

I have to say, I cannot remember, but this was very dense, very heavy, almost took another person to help me get it on the bed. I could not hoist myself. Maybe it was more like 60 lb. or so. I have yet to get one so heavy. I do love it, the best I have ever purchase, and one of 4 that I did buy. I would buy it again in a heartbeat. I put it over anothe 4 inch that I had, so all I am now sleeping on is foam. Super nice for my aching joints. charmur12001 on Oct 18, 2013

Can I put heated mattress pad on top of this memory foam topper elgintx on Dec 25, 2012
Subscribe to Answers
Answer This Question

It is not recommended. overstockcustomercare1 on Dec 26, 2012
Why is it not recommended? berg4713 on Nov 12, 2013
Hello berg4713, I apologize that more information was not given with the previous response. Memory foam reacts to heat and pressure from your body. If you have a heated pad directly on top of the mattress the mattress will not conform to your body as it normally would because of the heat from the pad. an electric blanket is a better option with memory foam as your body acts as a barrier between the mattress and the heat source of the blanket. I hope this is helpful. Thank you for shopping with us. overstockcustomercare1 on Nov 12, 2013
