Review: Tempurpedic reels me back in... - I bought a $3500 Tempurpedic "Cloud Supreme" mattress about 6 years ago when I was having serious hip pain. The relief it brought was miraculous. But, after roughly two years, that same mattress began to sag in a most unpleasant way. Sleeping in the deep "canyons" created by the foam giving way made my sleeping hellish - or more accurately - way too hot. Now I have more arthritis in my hips and my shoulders and found myself with a problem. I detested sleeping on the mattress and wanted a new one, but the thought of an innerspring mattress' springs pushing back up on my pain points was too much to bear. And there was no way I was ever going to spend $3500. on another Tempurpedic that would probably last me only another two years. So I suffered and frankly, was too anxious to try anything else - even the new hybrids - part foam & gel, part springs. Finally, I couldn't take it anymore and decided to buy a mattress from an online company that really will take back a mattress that doesn't work out - they don't have a business without that perk. I ordered one with a Euro pillow top because I like a softer bed. I would classify the mattress as a "light hybrid." Turned out that what the mattress manufacturer considered "soft" and I considered "soft" were about as far apart as can be. But, I decided that since I had a few months to try it out, I would try some "topper-like" modifications. I tried a few things we have around the house and got close, but nothing quite worked out. Despite my "falling out" with all things Tempurpedic, I could still recall how miraculous the mattress was the first two years I owned it - it MILDLY conformed to my body then (no disappearing halfway into it). The sleeping was excellent and without pain. There really IS something to the idea that metal springs can and do push pressure back up into parts of your body and causing pain. So, I decided to give this topper a try - $300 definitely is more affordable than $3500. The topper brought me back to the feeling that I was sort of "skimming" the bed. The arthritis pain was disappearing. I've never cared for the "conforming" feeling of any Tempurpedic product. Also, truthfully, I LOATHE the absolute flatness of the top of Tempurpedic products. Perhaps I am too "old school," but I like a layer of soft and pillowy next to my body. Tempurpedic never worked for me in that way. At that point, with my pain gone with the new mattress and the TempTopper, it occured to me that I could try a topper on top of the 3" Tempurpedic topper (for the record, "toppers" of any kind DO NOT work well with a Tempurpedic mattress - especially if you have pain). So I spent hours reading here on desertcart looking for the right pillowy softness for my topper's topper! I needed the right height, the right fabric and a texture on top that showed and felt "pillowy" through my sheets. I had left that absolutely flat Tempurpedic mattress top in the past - along with it's ridiculously sinking hot hole. Luckily, I found the right topper to suit my sleep needs. So I feel great. The new mattress I bought cost less than half of the disastrous $3500 Tempurpedic Cloud Supreme. The Tempurpedic 3" topper ($300) took care of the pain caused by "springs pushing into my hips and shoulders." The "pillow topper" was less than $100 and takes care of making my sleeping experience comfortable and plush. The best part? As I see it, the only thing that go wrong with this new "configuration" is the Tempurpedic topper perhaps getting a little too soft years down the road. It's only 3 inches high. How much could I really sink? And if I do eventually, I can live much easier replacing a $300 piece of foam than a $3500. mattress for the exact same amount of pain relief. I am a HAPPY CAMPER! Review: Fantastic product! - My wife and I absolutely love this new mattress topper. Best sleep we have had in years! I know it's a bit pricey but trust me it is worth it.

My spine and hips stuck with it, difficult to change positions. I had to begin to find alternative arrangements until I bought newentor. it gives me proper softness and support. My back never hurt again. **Q: I got the soft cooling topper. It smells intensely. Will it ever go away?** A: Beware. The smell can last a very long time, gets into your home, and if you smell it you may develop health issues. Irritation of airways and eyes, sudden awareness and heart rate changes (racing). Because of these products I cannot be around anything polyurethane now. Your face is on this ⅓ of your life. Listen to what your body is telling you. I know others who have had same experience. Get latex foam. No harmful chemicals. **Q: What’s the return policy if I don’t like it?** A: I believe you have 30 days to return it. Warning though: Amazon gave me a store credit gift card instead of crediting my store credit card! **Q: I absolutely hate how slippery it is. It is like a satin ferl and makss my shhets not fit properly. Anyone know how to rectify this?** A: They recommend not adding a mattress pad.

Would definitely recommend this mattress topper to anyone looking for a great night's sleep/rest. ### ⭐⭐⭐⭐ Pretty comfortable and doesn’t get too hot *by N***N on August 7, 2026* Bought a pricey firm mattress from S&Fs thinking it would increase the rigidness of the springs, not make the pillow top more firm. I was wrong and It was super uncomfortable, but put this on top and it’s actually pretty nice. A little soft for my taste, but it’s held up for over a year now and it’s a huge improvement over the mattress without it. Tried taking it off after a year and the mattress was still not comfortable without it. Not a big fan of the straps that keep it on either. They could definitely be designed better, but they work. If it was cheaper it would get 5 stars; but at this price point there are some improvements I’d want. ## Frequently Bought Together - Tempur-Pedic TEMPUR-Adapt + Cooling 3-Inch California King Mattress Topper Medium Luxury Premium Foam, Washable Cover, Medium Cooling Topper,White - Tempur-Pedic TEMPUR-Cloud Pillow for Sleeping, Standard, White - Tempur-Pedic TEMPUR-Cloud Dual Cooling Pillow, King (Pack of 1), White --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/159098637-tempur-adapt-cooling-3-inch-california-king-mattress-topper-medium](https://www.desertcart.jp/products/159098637-tempur-adapt-cooling-3-inch-california-king-mattress-topper-medium) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-27*
