Twin XL 3 Inch iSoCore 3.0 Memory Foam Mattress Pad, Bed Topper, Overlay Made From 100% Temperature Sensitive Memory Foam

I waited a few weeks to write a review in order to thoroughly test the product. After leaving it spread out overnight, it shaped itself almost perfect with the exception of a few minor spots. After the product was decompressed, I placed it on top of my very old spring mattress. The pad itself is a little bit larger than my queen size bed but, nothing to really fuss about. The comfort level is great, especially for the price. I slept all the way through the night minus one time waking up due to a little heat. Yes, this foam topper will make it a bit hotter than normal but that is to be expected with any type of foam that isnt designed properly with heat dispersion. After adjusting the climate in my home, I slept all the way through the next night and continue to. The reason it did not get 5 stars is due to its form holding. After just a few weeks, my bodies indention started to stay in the foam and would not bounce back to its normal state. For the price and comfort level, it is unmatched! I have since flipped the foam over to a new spot and hopefully my old spot will eventually straighten itself back out. It does turn yellow fairly quickly and has a small odor at first but, that is to be expected. Overall, I am very happy with the product and will buy another once I have run out of normal uncompressed places to sleep on it.

My opinion of the iSoCore 3" Memory Foam Mattress Topper offered by All Sleep is that this product is an outstanding, high quality product that is far superior to other mattress toppers on the market that cost hundreds of dollars more. What a great purchase! I actually made this purchase for my sister-in-law, who is quite the connoisseur of mattress toppers. She already has 2 of them on a queen size bed in a guest room and 3 of them on her king size bed and was planning to get another recently when a store @ the mall was having a $50 off sale. Even with $50 off, that mattress topper would have cost her almost $500! I thought that was ridiculous and suggested that she let me look on Amazon for her. When I came across the iSoCore mattress offered by All Sleep, my Mattress Connoiseur sister-in-law (who always buys ONLY high-end and designer products) was VERY skeptical due to the low cost of this mattress topper ($98.49/free shipping for king size!) But the reviews were so overwhelmingly positive that we decided to "take a chance" and placed an order. That was on a Thursday, and by the following Tuesday, the mattress topper was already delivered! My sister-in-law and I were very impressed by how quickly the mattress topper was delivered, as well as the fact that a king-size mattress was able to be shipped in a compact, easy-to-carry & easy to open box. But even more impressive is what we found once we opened the box: a clean, bright-white, ODORLESS, mattress topper that "puffed up" almost immediately! This mattress topper is amazing! My sister-in-law let it sit on top of the bed in her spare room for a couple of days (per the instructions) to fully complete the "puffing up" process before transferring it to her bed, but I honestly don't think she needed to do that. (In my opinion, she probably could have used it the same night it arrived.) But none of those seemingly wonderful & impressive qualities would have mattered if the mattress topper weren't effective and comfortable to sleep on. But it is! My Princess and The Pea, Mattress Connoisseur, Sister-In-Law said that this mattress topper is unlike any other mattress topper she has ever experienced & that it provides her with the most comfortable & restful sleep she has EVER had! And no more back pain! She is absolutely in awe of this mattress, and I know without a doubt that if she ever wants another mattress topper that she will definitely order this exact same mattress from All Sleep. I am planning on ordering one too, which will be my first topper. I never thought the ones I saw in the stores were worth hundreds of dollars, & I could never stand the odor that emanated from them. But this one is TRULY comfortable (I tested out), unbelievably affordable, odor-free, and comes with free & fast delivery. I am definitely going to order one, and I wholeheartedly recommend this mattress topper to other potential customers as well!

purchased for two of our guest bedrooms to go over the top of very hard mattresses that were uncomfortable. They do require several days of just letting sit on top of the bed before they puff up to their full size and let go of any creases from packing. The sit time is lessened if they are in a warm room...our small guest room is warmer than the queen sized room and it took only 48 hours for that one compared to 5 days in the colder room. Thickness is excellent, a good 3" as stated. They are a lot firmer than I expected them to be...I have a sleep number mattress on my own bed which I have at quite a soft setting, so bear in mind that most mattresses feel unbearably hard to me personally, but it was not as soft a foam as the 2" twin sized pad I take with me when I travel to offset hotel mattresses. My daughter has used the one in the small twin guest room and states that it feels comfortable, and it certainly feels much better when I lay on that bed too.

As many college dorms have twin XL beds, this is a quick and easy way to make a dorm bed slightly more tolerable. It comes tightly packaged which is nice, but it does take awhile to expand out to full size. Many others commented about the smell (and there's even a disclaimer on the package), but personally I didn't notice it after the first night. 3 inches is definitely not as thick as I had imagined in my head. There are some comparable pads at 2 inches, but I would definitely recommend the thickness this one comes in or thicker. Personally, I got it for back problems. It hasn't totally solved them, but I'm waking up with fewer aches and pains. It took me awhile to get used to and I was in pain the first 3 or 4 nights, but it's been at least a month and I definitely would recommend this product (although maybe a little thicker). The added thickness makes putting sheets over the mattress a little difficult, but that inconvenience is worth the extra comfort
