We're very pleased with this mattress topper.

This mattress topper is just the right softness/firmness for us. It has made our bed very comfortable. I've had less discomfort in my left shoulder while sleeping on this new topper.

The worst…

I wish I could give zero star… it’s cooling for first 10seconds then it’s not at all… we have back injuries and every morning we woke up with terrible pain of body. It’s bad but it’s even worse with this mattress.. I wish income return it but we are stuck with it. I don’t know how some reviews said comfortable. Maybe they never bad back injury.

Decent topper for the money

Thx topper isn’t as firm as I would like, since I have some back problems, but it is better than the tempurpedic one I tried. It is comfortable for most people. The 10 year warranty will never be used since it states it has to be depressed 1.5” before it can be utilized. If I waited that long I would have many more back problems.

Made my mattress even better. Relieves pressure on the hips. This is my second purchase as I’m placing it in the guest room. I can’t say enough good things about this pad.

Please read before purchasing

We decided to purchase this topper even though a review had warned of the foul smell. Once opened, the awful smell permeated the room. It smells of death and soiled diapers. I do not know how anyone would willingly put this on their mattress. I called customer service to return and was told it had to be picked up. I was told I would receive a call to schedule the pickup. Later that day I received an email with a return label for Fed Ex. IT IS IMPOSSIBLE to place back in original box. My husband had to buy a big box from a storage company to be able to send via Fed Ex. Please save yourself the time and aggravation and DO NOT PURCHASE.

Good Topper

We have an 18" King mattress and were worried our sheets wouldn't fit but our Giza cotton sheets fit right over it. It's comfortable and not as hard as a former foam topper we had. It really doesn't have much of a noticable cooling effect. We did have our heavier mattress cover on it, instead of the one that comes with it. We thought that might be the issue with no cooling and changed the covers out. But, there really wasn't much of a difference. Also, I am very reactive to smells and it really didn’t have any type of chemical oder. It fluffed up in one day and we slept on it that night. All in all, a good product at a good price and it saves us from having to buy a new mattress for awhile.

Great Purchase

I purchased this about 5 months ago. We had just purchased a new temper pedic bed to replace a 15 year old temper pedic bed. Without going into the long detail we ended up with a firm temper pedic mattress which was like sleeping on concrete. My wife and I both woke up in pain. We were told the mattress pad would not make a soft mattress firm but could make a firm mattress softer which is what it did. The topper has been great. Adds the right amount of cushion. Temperature wise, it is about the same as our old temper pedic. It starts out cool and warms up but not bad. I would buy again.
