    • Amazing

      Believe this review. I was skeptical that bed could be so great; given the price. It's incredibly comfortable. No need for a box spring if you use on a platform.

      I've had this mattress for a year now and is just as awesome as the first night we slept on it. I am a chronic pain patient and this mattress gives me the support I need all in the right places.

    • Great mattress, great value!

      I purchased a queen size memory foam mattress several years ago from overstock. It was great. When upgrading to a California king it was a no-brainer to look again at what overstock had available. They did not disappoint, I have been sleeping on this for a couple weeks now and it is the most comfortable mattress I've ever slept on. It is the right level firmness for me and you will be sleeping like a baby. I highly recommend this mattress, it feels like it should cost three or four times what it does.

    • Love it - great bed!

      Folks, this bed is as good as everyone is saying. We got the Cal King and dropped it in our waterbed frame. Had to raise the headboard, but that was the only thing. - This mattress is firm but comfortable. I had been having a lot of back issues before with the waterbed - hubby outweighs me by 60# or so, but my lower back and neck feel great now. Hubby is still trying to get used to the bed, BUT his snoring is almost non-existent now. :) As time goes by I think he likes it more and more. - I didn't notice much of a smell but we did let it air out for a day. - It is amazing how fast it expands once you take the plastic off. Have someone to help you lug it into the house and get situated and the plastic off. - Totally satisfied! And I would definitely buy another one. :)

    • memory foam mattress

      We have been sleeping on the mattress now for several months and we love it. We get a much better nights sleep. You can not feel any movement when the other person set down on the other side of the bed.

    Questions & Answers

    • I'm looking for a box spring, preferably a matching one? Any recommendations? Thanks!

    • Does the mattress need to be taken out of the box immediately, or can it stay in the box a bit?

      • We do recommend unpacking the mattress and letting it expand within 72 hours of delivery.

      • It's probably better to take the mattress out of the box as recommended BUT I purchased this mattress sometime in late 2015 & for multiple reasons, I didn't take the mattress out of the box until early March 2016 --- approximately four months after I received it. I can't remember exactly when I purchased the mattress & the bed frame. The mattress is perfect for our spare bedroom. I had guest sleep on the mattress approximately 12 hours after taken out of the box & they said it is perfect in all ways, size, comfort & no odor. Got the frame put together & put the mattress on it a week later & the mattress fits the frame perfectly. Now all I need is a big screen TV in the guest room & they will probably never leave.

    • Do I need to buy a memory foam mattress protector as well or does the included "4-way Stretch knot waterfall zippered cover" work just as well? Thanks!

      • Hello Aaron P., this mattress does come with a 4-way Stretch knot waterfall zippered cover for the mattress to help protect the mattress. Thanks for shopping with us!

    • Would I need a box spring with this mattress?

      • Hello Wyllow, the need for a box spring will depend on the type of bed frame you use. A box spring is not required for platform style beds. Thank you for shopping with us!

      • I purchased platform frame & no box spring necessary. Works well. Mattress is great.

    • Does this mattress sleep hot?

      • Hello meblea, memory foam does tend to retain body heat, if this will be an issue for you, it's recommended that you purchase a mattress that has gel, which will help keep you cool. Thanks for shopping with us!

    • The mattress we received doesn't match the product picture. Which side should be up when you place the mattress it in the bedframe?

      • Hello GnK, thank you for your inquiry; you will be contacted by Customer Care.

    • Does this mattress make a noise when you lay down on it? One of the reviews complained about a crinkling noise whenever you roll over, which seems weird to me for a memory foam, so I'm looking for other opinions. Thank you!

      • Hello lhoetger, this memory foam mattress is designed not to make noise when you roll over. Thank you for shopping with us! A.C.

    • What's the manufacture warranty on this mattress? How do we obtain the warranty?

    • Does this mattress come with a box spring if not where can I get one

      • The mattress will need a frame sold separately, below the mattress look at the recommended items to buy. They show a medal frame Pragma California King bed, we already had a waterbed frame & was a perfect fit. Love it!!

    • Do regular California King size & depth sheets fit this mattress?

      • Thank you for your question blavarias. We cannot say for certain which sheets will fit. Each company’s product tend to vary quite a bit. You will just need to verify, that the sheet height is at least 14 inches, the width 72 inches and the length should be 84 inches. Have a great day.

      • Yes

    • Is this mattress all foam? Also I've heard that foam mildews is this correct?

      • For the question about is this mattress all foam, yes it is all memory foam. Now, anything that is kept in a moist environment will mildew and old foam had a tendency to mildew more often and faster than normal but the new memory foam is engineered a lot differently today. It is made to be naturally fire resistant without chemicals or such and the mildew factor is a thing of the past. It is more resistant to those things and is a better quality product than it has ever been. Thank you for shopping

      • Foam with a layer of a cooling agent under top inch of mattress. Good quality foam. We are very happy as my husband has very bad arthritis.
