    • Ahhhhhhh

      Bought for an RV over-cab bed that has an upholstered board "mattress". Slight odor when opened, which dissipated within 15 minutes. Seemed to be too big for bed at first...but as it plumped, it got shorter and not as wide. Fits perfectly! Have slept on it 20+ nights and enjoyed the comfort...while roughing it!

    • SOOO comfortable but can get hot

      I absolutely LOVE my mattress topper. Let me say that I am a 30-something woman to give context and I like really soft mattresses. I was having neck issues sleeping on our tempurpedic. This completely eradicated any strain and I even sleep without a pillow now. My only forewarning to people is that it can get pretty hot, which I'm hoping I'll appreciate in the winter, In the summer it's fine if you sleep without a duvet but wanted people to know that prior to purchasing in case you have a higher than normal core temperature. I'm almost always cold; so it doesn't bother me, but my husband is like a furnace. If you co-sleep, make sure you let your spouse/partner know that it can be a factor. Other than that, I could not be happier. Lesson learned that all I need is a $200 mattress and a $150 pillow topper rather than a $1,500 temperpedic to sleep well at night.

      Did not fit the mattress. It is the most uncomfortable thing I've ever slept on in my life. My back has never hurt as bad as it does now. I would rather sleep on the floor.

    • Great for chronic back pain

      I initially bought the 4" memory foam for my queen sized bed at home after a car accident almost 2 years ago. It took a bit to get used to sleeping on it (I felt like I was sinking into a giant marshmallow) but now, I hate leaving home because I sleep terribly without it!! When I was scheduled for back surgery, my family and I made plans for me to recover at home with my folks. I ordered the twin sized pad for my bed there and it made recovery so much more bearable. It allowed for me to sleep on my icepacks with ease and gave me both much needed support and cushion. My dad opened it up and left it to air out a couple days before I was released to go home. There was NO CHEMICAL SMELL (unlike my queen sized Serta pad - which still smelled for 2 weeks after I opened it up). I do have a tendency to sweat on the pads if they are only covered by a sheet but I cover them with a cotton mattress pad and it remedies the problem. I LOVE THESE. My massage therapist suggested the pad to me and said 4" was best, 3" would suffice, but nothing less as it would just be a waste. I'm so glad I listened to her!!! It was the best money I've spent!!

    • First night, high praise

      First off, I think the "rate the comfort of this product" slider is a bit inaccurate. My rating is "average comfort" because it is right in the middle of softness and firmness, yet I find the rating language to be deceptive. Memory foam is a firm material that cushions your body's contours, and it feels like sinking into a dense yet fluffy marshmallow- it's soft enough to sink into but firm enough that it takes a while for the material to spring back. The comfort is DEFINITELY above average, and the memory foam yields an equal mixture of firmness and softness. Overstock.com, if you're reading this, perhaps you could consider changing the language to say "very comfortable or very uncomfortable", or else make your question about the density of the material so "very soft" and "very firm" make more sense? Anyway, I bought this to extend the life of my almost-10YO Ikea mattress rather than invest in a brand new bed altogether. This morning, it was SO hard to get out of bed. Boyfriend also remarked at the huge difference he felt immediately after lying down. When I woke up, I had no stiffness or soreness in my shoulders and neck. Felt totally rested. The product has a slight chemical smell upon opening it, but airing it out makes the scent dissipate, and I let it sit on top of my bed to aerate and reform itself (it comes rolled tight in a box so it needs time to shape itself) for about 4 hours. After that time, the scent was 90% gone and it had retained its original shape. Some reviewers have told about the intense smell or long time they had to wait, but perhaps this period is dictated by the sensitivity level of your sense of smell. I didn't have to wait long at all, and only smelled trace chemical scent when I hit the sheets. This morning, the smell was entirely gone. Also, this product is 100% memory foam/polyurethane, whereas some mattress toppers are only 2" of the material on top of cheaper foam. Folks, this is the real deal and I must say, it is a god-send. Also, it took about a week to come in, which was neither too long or short a waiting period. If you need a mattress topper, this is the one. Today (1/16) is the last day to get it at sale price, so act fast! I am beyond happy I invested in this and I look forward to staving off bed shopping for another few years. Can't wait to get back to bed tonight!

    • Comfortable addition to old matteress

      This is the second "topper" that we have purchased and are very satisfied. The first one lasted over three years, so it was about $50 a year. Very comfortable, and it makes your old mattress new again. We just put a board or cardboard under the topper, and it smoothes out the lumps and the topper is perfect. Much better and cheaper than a new mattress. Comes in big box and unfolds.

    • Used to make cushions

      I already enjoy memory foam on my beds at home and in my RV. My outdoor furniture cushions needed to be repleced, and they are pricey to buy. Instead, I bought this pad, cut it up, and voila - I now have better cushions and a much better price.

    • Love it

      We bought this mattress pad for my mother. She wanted it as a Christmas gift. She absolutely loves it. Her bed was getting old and very uncomfortable, it was making her back hurt all the time and she couldn't sleep. Now she sleeps through the night and gets a full nights rest. I would totally recommend this product to anyone else looking for a more comfortable nights rest.
