About this item

  • SOFT & FLUFFY - We utilize 120gsm thick brushed ultra-fine fibers as the sleep surface, providing a cool and breathable feel. Filled with 800gsm 5D spiral fibers, thicker than most on the market, the fiber filling maintains exceptional softness and elasticity, making this mattress topper exceptionally fluffy. It creates an extraordinary sleep environment
  • ELEGANT & DESIGNED - The unique box quilting design ensures that the filling is securely fixed in each box, preventing it from shifting easily. The elegant and simple colors complements the bedroom well, giving it a fresh and renewed appearance.
  • REVIVING YOUR OLD MATTRESS - If your mattress is too firm, adding our mattress topper cover is an excellent solution. It adds softness and comfort to old, hard foam mattresses. This is also an economical way to extend the life of old mattresses without needing to replace them with expensive new ones.
  • DEEP POCKET & EASY CARE - Quilted Stretch-to-Fit (8"-21"): The knitted skirt pocket stretches up to 21 inches deep, fitting most mattresses easily. A 1.6-inch wide sport elastic trim securely holds your mattress topper in place, and its excellent elasticity makes it easy to fit and remove. This ensures the most restful and restorative sleep. For optimal care, machine wash in cold water. Avoid using bleach and tumble dry on a low setting to maintain fabric quality and appearance.
  • OEKO-TEX CERTIFICATION - SLEEP ZONE has more than 40 years' experience in the design and manufacture of bedding. Our products are OEKO-TEX Standard 100 certified. You can buy with confidence.

Added a soft layer to a twin size camp cot

AnnaAugust 8, 2023

This is for a twin xl bed, not a camp cot. But I needed something in a hurry, so Prime next day was important, I needed something larger than a standard camp cot mattress, I didn't want to spend too much, and it needed to be easy to store, and it couldn't be inflatable because of a dog who thinks it's his bed. :) I was pleasantly surprised by how comfortable it made the cot, which I slept on all week while visiting. I'm 57, 5'8" and curvy, (pleasingly plump) and this added a nice layer of softness to the cot. It plumped up even more after being washed and dried, and washed nicely (follow directions) with no shrinkage. The elastic bands held the pad firmly in place, and seemed very sturdy. I added a flat sheet to protect it, which tucked in nicely under the elastics, and completed my temporary bed with a top sheet, pillow, and fleece blanket. Very cozy, and my daughter was happy to have it on hand for future visitors. This is not what it is made to be used for, of course, but I believe it would be nice on a twin bed, too. Be aware that larger sizes might need to be washed in an extra large machine.:) Read more

Heavy Weight & Luxurious Topper!

RussJune 12, 2025

If you're looking for a high-quality, extra-cushioned, heavy weight yet cooling and super comfortable mattress topper—this is the one! The quality is excellent, it stays in place perfectly, and it’s a treat to sleep on. It makes a noticeable difference in the comfort of your mattress. Highly recommended! Read more

Not bad, but not perfect either.

MarynaJanuary 13, 2026

It took me a while to figure out this topper. It comes without instructions, and it's not at all clear what to do with it. The topper arrives thin and flat. It looks useless and doesn't match the product description. But it turns out that you need to moisten it a little and put it in the dryer for one cycle, and then it becomes more elastic and fluffy. It gains volume and becomes more airy. It's very strange that this isn't mentioned in the instructions. Read more

Very thick and comfortable

Amy FordAugust 9, 2024

It fits well and is very plush and comfortable. I haven’t noticed it helping with my lower back pain though. The quality is wonderful as well as the thickness. Good value for the money. Performance as I said it doesn’t seem to help with lower back pain, but I am a co-sleeper, so they don’t make anything to help with that. Haha The appearance is nice Read more

★★★☆☆

Too thin.

BevJuly 22, 2024

If you want a nice fabric that feels smooth and cool, this us great. If you're using it for added comfort then do not buy this. It's too thin. It's not going to give any added comfort. It's basically like laying on a comforter. It does not have thickness at all. Read more

Perfect for Ikea FRIHETEN Sofa Bed

J. BirdMay 12, 2023

I recently moved into my first place on my own. It's a micro studio of about 200 soft so trying to keep as much floor space as clear as I can is important. I ended up deciding I wanted to get the Ikea FRIHETEN Sofa Bed to have a 3 seat sofa during the day and a full size bed at night. Plus there is a storage space under the seat for sheets to be stored during the day and the sofa pillows during the night. It was perfect...except that it was really firm. To be fair the IKEA description does say it is firm and I much prefer a firm bed to a soft bed. But this was uncomfortable for every night sleep. I knew I needed a matress topper and one that would be able to be folded and fit in the storage space during the day. This matress topper was definitely perfect for this job! It softens the bed enough to be comfortable but not too much to be pillow-y. It also folds up well and fits perfectly in the storage space under the seat. Plus it is washable! If you have a firm sofa bed, this is a great choice! Read more

Better than nothing but not much

NickOctober 6, 2025

Don't waste your money. Get foam or something. Someone said its like a cheap sleeping bag and yeah if you slept on this on the ground it wouldn't provide more than a few sheets worth of comfort. Its better than nothing but not by much. Im beyond disappointed. If they had paid me id probably use it. But ill be ordering something else. Read more
