    Memory Foam Do's and Don'ts:
    • To maximize memory foam expansion; remove from packaging within 72 hours of receipt.
    • This product arrives very tightly packed. Please unwrap and allow 48 hours for this product to return to its original shape.
    • Being sealed in plastic packaging sometimes traps odors. A few hours of airing usually removes the odor.

    Due to the nature of Memory Foam the firmness level of every item is unique.

    Topper dimensions may be slightly smaller than your mattress dimensions. Size has been designed to allow you to easily secure your fitted sheet over your new memory foam topper.

    • Diane

      Perfect for my mom. She has a Tempurpedic mattress that was too hard for her and her hips hurt. We bought this thinking that it would help with the hip pain and it has. She sleeps now very comfortably.

    • This saved me

      I took this bad boy to Paris with e to live for a year where I was provided the most uncomfortable, rock hard, cheap ikea mattress they make. This pad changed everything- I just wish I got it sooner. I hope whoever has it in Paris now still loves it as much as I did!

    • 4 inch memory foam mattress topper

      I purchased this less than eight months ago...very disappointed in the poor durability/quality of the item. It has ripped in several areas very large pieces of the foam just from sleeping on it! Too much for such a short time of use!!! Not satisfied at all!

    • Gel Big Bump

      This memory foam mattress adds just the perfect softness to a very firm mattress. I was thinking I was going to have to store my firm mattress untill I added the gel big bump memory foam. I bought the 4 inch but I wish I would have gotten the 3 inch. The 4 inch is a little toonplush fore but I am going to keep it anyway. It still is a very nice memory foam.

    • Oh my goodness, it's like heaven to me!

      So this is what sleep is supposed to be like??? I'm normally up at the crack of dawn, hurting and hardly being able to move and I actually slept in! Didn't wake up in pain and was comfortable all night. For me this is unheard of. Oh my goodness, I was in so much pain and can't afford to go buy a new mattress, so I tried this. It is like heaven to me. I also have a gel, memory foam pillow I picked up from a store for $12.00 and both together are AMAZING. Family members have purchased these and told me about them and are totally happy. ***This is definitely worth the investment.*** AAAHHHHHHH ;-))

    • Delicious!

      Oh, my... I bought this topper because my four inch memory foam topper was just too hot anymore. Also, my dogs had clawed a hole in the center where they decided to sleep when the sheets were off being washed. So, I got this one, laid it out for a couple days to air out the chemical smell, and then slept so comfortably the first night on it that I found I woke up in the exact same position that I had gone to bed in! It is not hot like normal memory foam, and because of the bumpy, conical shape of the top, it is soooo cushiony and soft. Honestly, it is a true pleasure to sleep and wake up on this mattress topper. I love it and it was worth it. One thing to note: my bed is queen sized, but I bought the king size topper as it was the same price. After it was positioned on my bed and had expanded to its normal size, I cut off the extra with a chef's knife, which amounted to a 15" x 78" strip. I cut two 15"x26" pieces and placed them together, cone sides together so that they interlocked. Voila! A perfect pillow! The remaining piece I use as a body pillow. Both fit in normal pillowcases and work wonderfully: )

    • Comfortable bliss

      I had an older memory foam that I stopped using long ago because of night sweats, I was skeptical prior to purchasing this, but desperate for a good comfortable bed, I searched for months before choosing this one, 1st, I liked the density, 2nd, I like the concept of egg crate and gel together for a cooler bed, I used a mattress cover over this and it has not disappointed, will be getting 100% cotton sheets for an even cooler bed, Yes, it is slightly warmer than no topper at all, but the trade off is worth it because with my aches & pains I am sleeping comfortably, and feel like royalty in my bed now!

    • Tearing Apart ALREADY!!!!!

      I had this since March and it is now the beginning of July and it is already tearing apart!!!!! It is super soft and I was very excited about it when I first laid on it, but last week I was woken up because I could feel my body on my mattress (since this topper is so thick it was like I was being sucked in so it woke me up). When I further investigated there are tears all throughout the topper and ripped at my spot, so it is only a matter of time until the whole thing will have to be thrown away! SO DISAPPOINTED!!!!!

    • You won't be disappointed.

      We bought 3 of these toppers to supplement the low end mattresses in our travel trailer. We bought the king size and trimmed them to fit the non-standard beds. The memory foam provides a lot of comfort. The memory foam gel keeps the foam from getting too hot which is so important in the summer. I had enough left over to make a couple dog beds from the trimmings.

    Questions & Answers

    • Does this fit under a mattress pad or do you use under a fitted sheet?

      • Hello Shndar85, you would use this under a fitted sheet. Please let us know if you have any further questions.

    • Can this product be cut to fit on an RV mattress size such as 60 x 72 as we have a short queen bed in our RV.

      • Hello Gee, we don't suggest cutting this but purchase the closest size possible. I hope this helps. Please let us know if you have any further questions.

      • We have one in our RV and I don't see any reason why you can't cut it. Ours hangs over and drives me crazy so I'm going to cut mine. Just make sure you have a big surface to spread it out on and a sharp cutter or scissors. Mark it from the back to keep the line straight
