Description

Power your sleep with the comfort you deserve with the Tempur-Pedic TEMPUR- Adapt + Cooling California King Mattress Topper. This 3" thick memory foam mattress topper instantly improves the comfort of any mattress, evenly absorbing the force of your body and its pressure points to reduce tossing and turning so you can wake up feeling refreshed and ready to start the day. Featuring signature pressure-relieving TEMPUR material, the memory foam topper effortlessly adapts to your unique shape, weight, and temperature to offer the same pressure-relieving comfort and support found in our mattresses. It's designed to reduce motion transfer so you can rest undisturbed even when you're sleeping beside your partner, kids, or pets, helping everyone get the blissful night of sleep they deserve. For increased comfort and durability, the supportive mattress topper is protected by a breathable, cool-to-the-touch cover that keeps you up to 8 degrees cooler all night long and can be removed and machine washed as needed for easy cleaning. This medium-firm mattress topper fits neatly over California king size beds, and the Staytight corner straps keep your topper securely in place by creating a nonslip connection to your mattress.

    • This topper has been absolutely life-changing!
Size: California King Style: 3" + Cooling
We ordered the Tempur-Pedic Adapt with Cooling 3" topper through Amazon Prime, and it arrived in less than a day, which already felt like a win. It came in a surprisingly small box, wasn’t overly heavy, and was very easy to carry and place on the bed. When we first opened it, I’ll admit we were a little nervous. It was rolled up, lumpy, and looked thin, and we wondered if we had made a mistake. But within about an hour, it miraculously expanded, smoothing out completely, and it continued to get even thicker as the night went on. By bedtime, it was fully formed and fit our mattress perfectly. Sleeping on it is like sleeping on a cloud, the most embracing, nourishing hug. It completely relieves pressure points and gently cradles your body without feeling unstable or too soft. Our Tempurpedic Delux Breeze mattress underneath, although extremely high quality and sturdy, was simply too firm, and we were waking up with neck and back pain every morning. This topper completely resolved that issue. It is beyond heavenly. Truly pure perfection. If your mattress is too firm but otherwise high quality, this is the solution. We honestly wish we had gotten it sooner. The difference is night and day. 5 out of 5 stars. Highly recommend. You cannot go wrong. There are great sales every so often. We'd recommend jumping at the opportunity when one of those sales hits. ... show more

    • Bed topper
Size: King Style: 3" + Cooling
Most. Comfy. Ever! Removable cover is water resistant cloth- not plasticy, and washable. Looks great on our king size bed. We stay nice and cool all night. It’s a whole body hug, just soft enough and just firm enough! Corner straps keep it in place and it’s not so heavy that I can’t make the bed by myself! ... show more

    • Cooling cover smells absolutely disgusting
Size: Twin Style: 3" + Cooling
I did a ton of research on mattress toppers. I like really soft mattresses (side sleeper) and was trying to make my Brooklyn Bedding "Best Mattress Ever" model in Soft (it's from 5+ years ago, they don't make this mattress anymore) a little softer. I saw some reviews and posts online mentioning that the "formula" for Tempur-Pedic toppers has changed and they aren't as high quality/dense. I was prepared for this, as I read that they were still worth it over a cheap memory foam topper. I don't know what the old one was like, as I've never had one before. Tempur-pedic currently has 2 models of their topper...the TEMPUR-Topper Supreme (which they rate as medium-firm, made with original Tempur material) and the TEMPUR-Adapt + Cooling Topper (which they rate as medium, made with Tempur ES aka "Extra Soft" material like some of their "Soft" mattresses now have). Being that I was trying to make my already soft rated mattress a little softer, I opted for the TEMPUR-Adapt + Cooling Topper (which costs more). The topper arrived and I immediately noticed the smell before even opening the box. I figured the box smelled from being on a delivery truck. Opened the box and realized it wasn't the box that smelled and it wasn't the foam. The cover is separate (you have to zip it around the foam once expanded). The cover smells ABSOLUTELY DISGUSTING. Not like the normal foam off gassing or something, I mean just absolutely rancid. It seems to have some sort of gel/plastic layer for "Cooling", which I think is what smells (as the bottom of the cover without the cooling part doesn't smell at all). I aired the cover out on my outdoor clothesline all day in the sun and wind, but it didn't change the smell at all. Let it air out in a different room for another day, still on change. I did NOT try washing it, but it smells so bad I don't think I would want it in my washing machine (yes, it's really that bad). As far as the foam itself goes -- this is NO better than a cheap 3" memory foam topper. It's so soft that you sink right through it (tested with 175lb person and then with a 120lb person) and hit whatever is under it. It's literally like it's not even there. I have an ancient 1.5" memory foam topper (some green tea thing from Walmart) that was really cheap and it feels better than this Tempur-pedic one even after 6+ years. I should probably try the TEMPUR-Topper Supreme version, as the medium-firm might hold better without sinking through it. However, after this experience with how the cooling cover smelled, I won't try the other one as I don't want to keep returning them. Tempur-pedic should be embarrassed to put their name on this product between the disgusting smell and poor performance. Definitely not worth the price, that's for sure! ... show more

    • Amazing sleep for side sleeper
Size: King Style: 3" + Cooling
Oh my goodness. The difference this has made in the comfort of my bed. I am a side sleeper and I have not been able to find a mattress that truly relives pressure from hips to prevent hip and back pain. With my mattress only being 6 months old, I de used to try a topper instead of ANOTHER mattress. This is truly a sleep saver! ... show more

    • Expensive. But provided immediate relief.
Size: King Style: 3" + Cooling
After about two months of progressively worsening shoulder pain, I’d finally had enough and decided to try this topper. I have a firm mattress that’s been great for my back, but as a side sleeper, it was absolutely killing my shoulders. What started as pain in one shoulder turned into both because I kept switching sides trying to get relief. I noticed a difference the very first night. I slept through the night without tossing and turning, woke up refreshed, and my shoulders felt worlds better. I haven’t slept that well since before we moved to this firm mattress! The topper gives just enough pressure relief for side sleeping while still keeping the support of the firm mattress underneath. My back still feels good — maybe the slightest bit less firm than before, but absolutely worth it for the shoulder relief. Yes, there was a smell when I first opened it, but I let it air out for 2–4 hours, then put a mattress cover and sheets on, and I didn’t notice it at all after that. I was able to sleep on it the same night it arrived. It’s expensive. That almost stopped me from buying it, especially knowing returns for something like this is tricky. But it’s still far less than replacing a mattress, and the improvement was immediate. I would absolutely buy it again. If you’re a side sleeper on a firm mattress and dealing with shoulder pain, this is 100% worth considering. ... show more

    • Saggy mattress
Size: Full Style: 3" + Cooling
I took a moment to write this review. I purchased this mattress for my daughter. At first is was nice and soft, yet firm. My daughter loved it because it was cool to sleep on. But after a year, it began to sink in the middle. SO I would not recommend for durability.

    • Luxury Comfort Without the Luxury Price Tag – No Regrets!
Size: Full Style: 3" + Cooling
I’ve always been a Tempur-Pedic fan, having owned two in the last ten years, and I’ve always preferred them firm. But as the years passed, both my mattress and my body changed. The firmness I once loved started hurting my shoulder, and with some weight gain, I realized my mattress was no longer providing the right support. I seriously considered replacing it with another Tempur-Pedic, but before dropping $2500, I figured I’d give this topper a shot. And I’m so glad I did! It revitalized my mattress, relieved my shoulder pain, and gave me the perfect blend of support and comfort—all without the hefty price tag of a full replacement. One thing to note: this softer memory foam really lets you sink in, which feels amazing for joint support and relaxation. But at first, it did take a little extra effort to get out of bed compared to a firmer surface. That said, after about a month, my body fully adjusted, and now it’s not an issue at all. If your mattress feels too firm or less comfortable than it used to, this topper might be the perfect fix. Highly recommend! ... show more
