This product is not well made. The first time I put the cover on the bed it ripped by the seams around the zipper area- which makes the cover useless for creating a barrier for bedbugs. Also, the zipper came right off and there was no way of getting it back on.
I did not realize when I purchased this cover that it was like a " bag" so it was a chore for me to put it on my king size mattress. Plus the cover creates an intense amount of heat when sleeping which causes me to have to get out of bed to it can cool down. This may be good for my husband but is uncomfortable for me. I would not make the purchase of another one.
Terrible product. The concept is great however the quality of the product is cheaply made. The padding is almost non existant and it does NOT fit up to 12" maybe 8 at best. When I tried to get it onto my mattress, which also has a 3 in. foam topper it did not fit, was VERY hard to even get around the top of the bed to start putting it on and the plastic lining on the inside of the cover ripped and when I finally got it to the bottom it was not big enough to even pretend to be able to zip even with the extender. Would not buy or even try it again. I am hoping it works out better for the XL twin that I bought for my son for college.
This product is not durable at all. It ripped along the zipper and the zipper kept popping as soon as I put it on my mattress. The zipper is plastic and is too weak to hold the cover closed on a king sized mattress. Very disappointed in this product and the cheap construction. I didn't return it because I had already threw my old cover in the trash. Unfortunately, this one should be trashed too!
This is our second time buying this brand of mattress. It's a good buy and its very comfortable. BUT you should know that it has a very strong "off gassing" for quite some time. Similar to the smell of new carpet. After it arrived (it comes tightly rolled like a rug and needs to expand), we unrolled it and let it sit in our unused porch with the windows open for a week before bringing it in the house. That helps. However, even after that - for quite some time - you will smell the mattress. If you have chemical sensitivities or sensitivities to odor, this is not the mattress for you. If you have time to wait it out, or if that doesn't bother you, this is a great mattress. The smell does dissipate with time.
