  • Comfortable, but smelly

    I have no complaints about the comfort of the mattress, but the smell is pretty bad. I've had it now for almost 3 months, and I still smell the funky foam chemicals wafting from it. I left it unzipped and airing out for a really long time, and it still stinks. To be sure, the smell is not as strong as it was when it was new, but the reviews give the impression that the smell will go away in a day or two, and that is definitely not the case. Other than that, it's pretty comfy and the price is decent for what you get. I use mine as a guest bed, and haven't had any complaints.

  • Sleeping Better

    It's not as soft as I'm use to but that seems to be good for me because I'm sleeping a lot better. Less tossing and turning generally.

  • Most comfortable bed in the house!

    I purchased this over a year ago, and it has been the favorite bed for all returning family visitors. This is by far the best bed in the house, though not the most expensive!

    We purchased this bed mainly for my husband because he has back and SI Joint issues that keep him from sleeping properly. We have had a Sleep Number bed for about 6 years and at first it was fine, but over the years you need to keep adjusting it and neither of us can ever get comfortable. Both of us sleep wonderfully now at night - this is by far the MOST comfy bed I have ever slept on! When it was delivered we opened it up and let it lay flat in a spare room so it would fluff up and we were expecting a terrible stink (because of all the other reviews we read). HONESTLY, I got down on the darn thing and stuck my face in it and it hardly smelled at all! My husband has severe sinus issues and the smell would effect him more than the regular person and he was even fine with it. This bed is truly worth every penny we paid for it!!

  • Amazing Mattress!!

    I truly thought the reviews were written by people that worked for this mattress company until I bought the mattress. My name is Dotan Baer you can google me and you will quickly realize I have nothing to do with this website or this mattress company. Myself being a 90% disabled veteran haven't slept well in 15 years, and getting a good nights rest or any rest at all has been difficult if not nearly impossible; until this mattress!! This isn't my first time on a foam mattress, just my first time owning a foam mattress. If you are considering buying one, before you waste $XXXX, and buying things exactly the same material - buy this mattress. Does it smell? YOU BET it smells GREAT just like new foam! That is why you are suppose to allow it to air out for 24 hrs and expand properly preferably in a well vented room. This is the exact same foam as in the tempur pedic mattress and pillows, and this mattress comes with a top layer of hard foam which truly molds to SUPPORT your body where it needs it.

    This is a second time purchase. The last one we bought was 2 years ago and it is the best mattress we ever slept on. I mean it is seriously dreamy! I've had friends and family try it out and they were amazed also! One friend even purchased one for herself and loves it as well. So we purchased a second one for my mother and it was NOT the same mattress although it's the same item number. I couldn't believe how hard it was!! I contacted customer service IMMEDIATELY regarding this. It is not usable. The tags on it are a different manufacturer and even from a different country as the first mattress. I was reassured by customer service that this would be rectified. I was asked to provide photos as proof. I did this. Email and call after email and call.... I was eventually told No explanation except mattresses are not returnable. This is bad business overstock! It is COMPLETELY different from the feel to tags to country and manufacturer. I have purchased so much from overstock through the years. They lost a customer. I have switched my business to W******. If a company is this dishonest, I'm out. Do they not realize people are their business and customers come from other satisfied customers?!? Just the opposite has happened. I continue to spread the word. I switched my bed for my mothers as I would not let my disabled mother sleep on it. I purchased a 5 inch topper and it has helped....a little. It's been 6 months and I was hoping it'd 'break in' but to no avail. At best, it's tolerable. It will soon be making its way to a guest room because I can not do it anymore. Buyer beware.

  • nice mattress

    This mattress is VERY comfortable. It is a little thin for the standard deep pocket sheets, but if you have the fitted sheet with the elastic all the way around you should be fine. I would avoid the very deep pockets as those would likely be too big. I have been sleeping on this while having some construction in my master bedroom, and I am getting much better sleep than my normal inner spring mattress. It is a bit on the warm side, not sure how it will be in the warmer summer months, but seems to be fine with a light weight blanket. Great value and comfortable mattress for my guest room, which doesn't get used very often.

    • Based on reviews

    • I have pleased with the experience of sleeping on a gel foam mattress and finding one on at a 60% discount and amsale was a major factor in my choice. But my final decision rested on the many complimentary reviews of satisfied buyers. One complaint of the mattress being "too hard" is understandable if the buyer wants or expects a pillow soft sleeping surface. That is not my experience nor my desire.

    • The reviews were good, and this meets our needs. The fact that many stated the bed was a little shorter than a normal queen size isn't an issue at this is going in our 5th wheel, where the bed is actually already shorter than a queen.

    • Hello scramirez, you will be contacted by Customer Care. Have a great day.

  • How can you wash the outer cover which contains the aloe gel?

    • Hello epo, we do not recommend washing the aloe gel mattresses given that in doing so, it can ruin the gel. We recommend spot treating it. Thank you for shopping with us!

  • Does this mattress have total of .5 inches of memory foam? What type of foam is used in the 3 inch layer?

    • Hello sleepneedy! This mattress looks so comfortable! The ship weight of this product is 50 pounds and the package measures 13 inches high x 14 inches wide x 61 inches long. I hope this helps. Thanks for shopping with us.

  • What does this mattress weigh?

  • Can this type of mattress be used with a heated mattress pad without causing damage or extra wear?

    • Thank you for your interest. "You can use an electric blanket/heating pad with your mattress, yes. However, you should remember that memory foam reacts to heat and pressure, so if the heating pad is placed directly onto the mattress (i.e. under your back), the memory foam will react to the heat of your electric pad, not your body. This can disrupt the memory foam's ability to conform to your exact shape. A heating pad will not cause permanent damage to the memory foam. If you decide to use a heating pad, we recommend placing it over top of your body, rather than underneath, so there isn't as much direct contact with the mattress." Please feel free to contact us again with any further questions.

  • Is the gel layer one inch thick or 0.5 inch thick? I need to know before purchase.

  • what is the firmness of this bed?

    • This mattress is semi-firm. Memory foam mattresses contour to your body, so at first it will be firm until you lay in it for a few minutes. From there, it will mold to your body making it a little softer.

  • Who and where was the memory foam manufactured?

    • We''re sorry to say that we don''t have manufacturer''s information made available to us for this particular item.

  • could this be used on a hospital bed frame?

    • It would depend on the size of the bed frame. This mattress measures 59 inches wide x 79 inches long x 8 inches thick.

  • Would one need to put a bunky board underneath for use on a bunk bed or should it be fine without it?

  • The description of this item references a one inch layer of gel. When I read the product details, it says there is only a half inch of gel. Which is correct? thanks

    • Thank you for your inquiry. The gel infused memory top layer is 0.5 inches thick.
