  • Five Star
We are very pleased with this four inch mattress pad. We ordered firm to extra firm and it really is exactly what we were hoping for. High quality products, exactly as described. We saved a lot of money by not buying a new mattress, just this king size topper.

  • Firm Topper, Hard to Locate.
This three (3) inch mattress topper is listed as a firm, very pleased to locate it. Comes with a removable exterior cover, easy to clean. One issue seems to be it sleeps hotter than others tried, but due to the level of firmness? Will try to deal with the temperature issue. Needed to leave open out of plastic for over nine (9) hours for full extension. ... show more

  • Bed feels much better
I ordered this for my daughters bed. Her mattress is only 2 years old and was quite expensive. But she’s said almost from the beginning it hurts her back. One night I went up and slept in her bed so my husband could watch TV in our room and when I woke up the next morning my back was killing me. So I ordered this topper. Wow! First of all, it gives good support without being hard, just firm. Unlike most foam or memory foam toppers I’ve seen (or owned), this is invaded in a soft zipper cover. It Made the bed so much thicker though that it was very difficult to put the sheets on. Not deep enough pockets. This will make your bed high. It is not hot. If anything, it seems like it gives a cooling effect. All in all, it’s been great so far. She hasn’t complained about her back hurting since I put it on. ... show more

  • Best mattress topper
Size: Queen Style: 4 Inch
This mattress topper is thick, comfortable and well made. The straps at all 4 corners keep even the most unruly mattress exactly where it should be. We noticed an immediate improvement in our sleep right after we started using this. Once you take it out of the box you’ll need to let it breathe and “unsmush” itself for about an hour but after that it’s ready to go. You’ll need deep pocket sheets to fit over this but it’s an excellent value. This would make a great housewarming gift. ... show more

  • Love it!
First and foremost, the firm to extra firm memory foam is perfect for those who suffer from back pain. Since I started using this mattress topper, I've noticed a significant reduction in my back pain and I wake up feeling more rested and refreshed. The high density foam provides excellent support and keeps my body in the right position throughout the night. Installation was a breeze - I simply laid it out on top of my mattress and it fit perfectly. The topper doesn't shift or move around during the night, so I don't have to worry about adjusting it while I sleep. Overall, I highly recommend it to anyone who wants to improve their sleep quality and alleviate back pain. It's an excellent investment that is well worth the money. ... show more

  • Thick and comfortable
Size: Queen Style: 3 Inch
This is a great buy! It fits my queen bed perfectly. It’s thick and very comfortable. Heavy duty. The straps that hold it on your mattress are adjustable. It has a slight smell when first opened. I let it air out overnight and it’s gone. Definitely recommend!
