  • Positive Review

    After patiently waiting our mattress topper finally arrived. We haven't slept like this in a long time. We are sleeping soundly, and waking up with no aches and pains. This is a great alternative without spending thousands of dollars on a new mattress.

  • Finally, I good night's sleep!

    My husband and I absolutely LOVE this Memory Foam Mattress Topper! Before I bought it, I was tossing and turning all night and was not sleep well at all! Now, I am sleeping like a baby! I was ready to go out and buy a new mattress set (which includes the adjustable base), but I couldn't bring myself to spend over $^%$#@ without knowing if I would like this type of top. A friend told me to buy a memory foam topper to see if we even like it; so, that is what I did. Eventually we will need to buy an adjustable base bed and a new mattress, but for now, we are content with our recent purchase. Not only am I getting a good night's sleep, I don't wake up with the joint pain like I did before I slept on this Gel-Memory Foam topper. The only thing that I didn't really notice, was that it made the bed any cooler. I would advise you to really read about the differences in the foam density and what will suit your specific needs. I did review all of the various options and I am so glad that I did, as I would have ordered something completely different and would have been dissatisfied. I highly recommend this product!

  • just what i expected

    Foam topper just what I expected. Not as cooling as I would like but quite satisfactory.

  • All I can say is wow

    You really sonk into this topper and don't get overheated like the foam topers

  • Slumber Solution Gel Highloft 4-in. Memory Foam

    I love this mattress foam topper. This topper is well worth the money. If you want a super soft mattress topper this is the one. I have a medical issue where I must have a super soft bed so that the pressure points in my body can be relieved, this mattress topper does that better than any other mattress topper I have had. Sleeping on this topper is like sleeping on a cloud.

  • Good

    Maybe a little too soft, but I can't tell anymore, my skeleton is a twisted mess. It is comfortable, soft, and feels good and makes a great difference.

  • Very Happy with this purchase

    I am very happy with this mattress topper. It arrived on time. It didn't take long to decompress and the odor was minimal and didn't last long. Very comfortable, I definitely wake up with less aches!

It's been 2 days since I submitted my question- Your site claims to answer in 24 hours. I still need to know which side goes up, flat like the photo of the hand print, convoluted like the photo of the bed. Please respond. Thank you!  on Jun 9, 2012

Hi there, me again. Could u translate your previous answer into practical English (it has bigger bumps?) AND what does IT REALLY MEAN, etc? Is the one with bigger bumps softer/more comfortable, more aeration, etc????? michifur on May 24, 2012

Answer This Question

The product has slightly different model numbers but is essentially the same product. One is probably a newer model. overstockcustomercare1 on May 30, 2012
After seeing your answer, I called Future Foam, the maker of this product. The info I got from their rep basically said with the Big Bump, U sink deeper/cushions-conforms to your body more but that may be "hotter" for some sleepers?. Vs this item has much smaller bumps, 'firmer' feel/less sinking/maybe less hot? michifur on May 30, 2012

Thanks for the previous answer. But I was referring to item #14189805 (Slumber Solutions Gel Big Bump 4-inch Queen/ King/ Cal King-size Memory Foam Mattress Topper) which has the exact same density according to the write-up (3.2lbs). What is the difference between that item and this one? michifur on May 21, 2012

Answer This Question

They are both convoluted-style toppers. This one is standard-convoluted whereas #14189805 has a bigger convolution. Please feel free to contact us again with any further questions. overstockcustomercare1 on May 24, 2012

What is the total weight? And what is the difference between this topper and the similar 4" Big Bump Topper by Slumber Solutions? michifur on May 15, 2012

Answer This Question

Depending on the size you were interested in purchasing, the approximate weight is going to be around 15-20 lbs when fully expanded. The difference between this item and the Slumber Solutions Highloft Supreme 4-inch Memory Foam Mattress Topper (Overstock.com Item #12661391) is going to be the density. The density for the Slumber Solutions Highloft Supreme 4-inch Memory Foam Mattress Topper is 3 lbs and the density for this item (Slumber Solutions Gel Highloft 4-inch Queen/ King/ Cal King-size Memory Foam Mattress Topper) is 3.2 lbs. overstockcustomercare1 on May 20, 2012
