Experience absolute relaxation with this queen-size Trizone mattress by Grande Hotel Collection. The top layer of polyurethane foam molds to your body and adjusts to your weight for pressure relief and allows the mattress to return to its original shape when you get out of bed. Temperature-sensitive foam disperses heat from your body and promotes air circulation to ensure restful and undisturbed sleep on a cool sleeping surface, and the solid 5-inch-thick base layer creates a sturdy and supportive foundation.

  • European designed top layer uses 3" of conforming, elegant memory foam for your comfort
  • 3" layer of premium 3 lb density memory foam works to disperse your body weight evenly, improve circulation and reduce pressure points for better sleep
  • 3" zoned comfort support layer provides exceptional support for your head, torso and legs
  • 5" base layer is designed as a foundation offering balanced support for optimum performance
  • Made with polyurethane foam
  • Measures 14" H x 59" W x 79.5" L
  • Medium support
  • Originally designed for NASA, this memory foam conforms to your body and reduces pressure points to eliminate tossing and turning
  • Temperature-sensitive foam adjusts to your body temperature and draws uncomfortable warm air away from your body, keeping you cool
  • Eliminates motion transfer and uncomfortable pressure points for rejuvenating sleep
  • Disperses your weight evenly, helps rejuvenate sore muscles, eases back pain and improves circulation, so you feel great upon waking up
  • Meets all flammability standards for your safety
  • Mattress can be used with an existing frame for an easy installation
  • Great for platform beds and slatted frames
  • Meets all the requirements of the federally mandated regulations regulated by the Consumer Products Safety Commission, Part 16, CFR 1632 and 1633
  • Remove from packaging within 72 hours of arrival to maximize memory foam expansion
  • Unwrap the item, which arrives very tightly packed, and allow 48 hours for the mattress to return to it's original shape
  • After unwrapping, allow the product to air out for a few hours, as the plastic packaging sometimes traps odors
  • Due to machine-cutting manufacturing processes, there may be slight variances in the dimensions of this product

    This is one of the best mattresses I've ever slept on! My husband and I slept on this mattress at a friends home in their guest room. We had the best night sleep. Soon after we needed a mattress for our guest room and bought the same one. Our guests who have slept on it say it's the most comfortable and supportive mattress. If I have to come up with a negative it would be that when you sit on the edge it feels like there isn't a bunch of support under your knees. That's all I can come up with. The positives would be that there is support in all the places that you need it- head, shoulders & hips. It's firm yet feels soft. You can't feel when the other person moves in the bed. It's super thick so you can use it on a platform bed without a box Spring. Make sure to let it rest when you open it and don't lie on it too soon. It is amazing how well it forms up.

    This is the most comfortable mattress I have ever had. My husband is much heavier than I am and that has always been a problem with other mattresses but not with this one. I have recommended it to several other people.

    I've had this mattress for a few years. It's still firm yet soft. It is fairly easy to keep clean. It does retain a bit of heat which is awesome in the winter, not so awesome in the summer. Be sure to buy a cover to keep it a bit cooler.

  • Best Deal in 30 years!
    Verified Purchase

    When it came, it was rolled up. I thought I got ripped off! After letting it sit open for a few hours, it turned into, well, my heaven! Very responsive to my body weight (145lbs). In the mornings, I don't want to get out of it! That comfortable, it is! In the evenings, I prefer to surf on the laptop, laying on the bed, rather than lounge by my fireplace and do the same! Now, speaking objectively, in comparison to spring mattresses, this trumps them all. Pillow top and all..had them, no comparison. If you've had the thin version of the memory foam mattress and found yourself hitting a hard spot (ie. the platform of your bed frame), this I assure you, will not do that. If you've purchased a memory foam that ends up feeling like a hammock by the morning time, this again, does not do that. Truly identical to the memory foam mattresses I have slept in, at 5-6 star hotel suites over my travels around the, more affluent, countries. Excellent for side sleepers! If you prefer laying on your back, because I'm both, you will need a Goose feather or memory foam pillow of your liking. Final thought: The next level would be sleeping on a cloud of air with air jets pressing on your 5 pressure points.

  • About time
    Verified Purchase

    I spent enough time studying this product to qualify for a college credit just because for me this was a lot of money and I wanted to be sure I was making the best decision. I read over 350 reviews on several sites including this one before making my decision. It was my first purchase on OS and will not be my last. I have never slept so good. The past few years I never slept more than an hour or 2 without waking up in pain in my shoulder, hip, back and neck. This mattress cradles your pressure points and eliminates almost all my pain. I sleep as much as 5 and 6 hours without waking up. Firmness is perfect and I cannot believe how easy it was to set up. It was a few nights before I realized there is absolutely no noise, no creaking, no sqeaking nothing. I told my sister and she ordered one the next day from OS. A co worker asked me if OS was paying me to be a spokesperson for this mattress because I can't stop talking about how amazing it is. Also, it was by far the best price for the quality, trust me, I did my research. When I save some more money I want to buy a platform bed to put the mattress on. I bought the metal frame from OS also and I'm very happy with that quality also. Treat yourself to the best nights sleep you will ever have.

  • Best night's sleep
    Verified Purchase

    We've had this mattress for several weeks at least and had to leave it rolled up because we were moving in to our new house. Though we planned to paint our bedroom before we unrolled it, we got too far in setting up the bed frame and ran out of floor space in the room and had to put the mattress somewhere. So we unrolled it. A couple of hours later, we leaned on the bed to pick something up and we were amazed at how fantastically soft it was. We then decided we wouldn't spend another night sleeping in a bed that wasn't this one. It was the best night's sleep we've had in months. Not only was it soft and supportive, but I don't know how many times my husband rolled around in his sleep. That alone was worth buying the bed. We picked out a very simple platform bed, without a headboard or footboard, because we plan to make our own out of some old church doors. I also noticed that some people complained in reviews about how hot the mattress could get while sleeping. I purchased a mattress cover and that, I believe, helped keep it cooler. Though extra body heat isn't a bad thing since we live in a snowy state and are in the midst of winter. Hopefully it won't be bad in the summer.

  • Worth the money
    Verified Purchase

    I was a little skeptical of buying a bed online that I could not actually lay on first to test, but after reading the reviews I took a shot and am glad I did. My ex-gf had a tempur-pedic mattress that was approximately the same weight and size but she paid around $2500 for, so I was hoping this mattress was similar to that. It was. At 1/5 the cost. First, the mattress comes rolled up lengthwise, like a carpet, but is shrink-wrapped. The UPS label had a weight (queen size) and it said 90 lbs. So make sure you have some help getting it into your place if you are not able-bodied. Second, make sure you have some kind of foundation for the thing, as it does not come with anything but the mattress. My ex had hers on a piece of plywood which was on a bedframe and it worked fine, I simply threw it on my existing boxspring. I read some reviews about the chemical smell, which there was some, but it was not pungent like some reviews I have read on here. I let it air out for about 4 hours and it seemed fine. Also, I bought a vinyl mattress protector from Bed, Bath & Beyond for about $20, and wrapped the mattress up in it so as to keep it new, plus put my existing mattress pad over that. Being 6'6" and close to 275 lbs, it is legitimately one of the most comfortable mattresses I have ever slept on, and although I haven't owned it that long, I will update my review if it starts to sag or dip. Google "overstock coupon code" and look for a discount before you buy it, I saved an additional 10% by typing a code in I found online. Anyways, for the money, I would suggest this to anyone looking for a great night's sleep at a bargain price.

    I bought this because of my back I'm 275lbs. and would wake up with a lower back pain all the time with my other name brand mattress. Now that I have tried this for two weeks my back pain is almost gone and I'm sleeping all night long, I would highly recommend this to anyone. I received this seven day's after I ordered it, there was no smell when I opened it but I let it sit out for a day before using it. For the money you just can't go wrong.

    • A:

      Hi lsolrak, you would be ok if you used a heated throw with this mattress. This product does not have any resrtictions for heated blankets. Thanks for shopping with us.

    • A:

      Yes, I use a down bedcover. The foam will become the temperature of the room and at times its like sleeping in a water bed with no heat the mattress seems to suck heat from your body. You may want to create insulation between you and the mattress. Unless the electric cover is under your body you'll continue to have the same problem. Kelly
