Just what we were looking for. We have a super firm bed. That made our shoulders and hips ache while sleeping on our sides. This extra firm topper. Was the perfect solution. It’s still quite firm. But gives us just enough cushion to sleep comfortably. Great purchase for persons with back problems. It’s nice and enclosed as well. And secures onto the bed mattress with straps. We’ve only used it for a week. But we do notice a difference in our sleep. I highly recommend it.

This topper is not firm at all...to the contrary, it is extremely soft. When I put it on the bed and laid on it, I felt like I sunk down deeper into the bed than on the actual mattress itself. Also I ordered king size, and it was actually a couple of inches too long on all 4 sides. Worst part is, now that it's out of the suck wrap, it's too big to go back in the original box for the return, and I'm having a hard time trying to find a box to put it back in, since "boxing" it is required for the return. This item for me has been nothing but a headache.

Unfortunately it is larger that an my king mattress. It goes beyond the mattress by obout 2 inches. Thus difficult making the bed and being some what of a perfectionist looks bad. It does feel firm, which was an important feature for me. I would have returned it , but, I am in the process of returning another mattress pad that was barely 2 inches and another order that they were unable to deliver when it was needed. I am exhausted with the process.

IMO this is a very good purchase. I have no complaints. I am a 75 yo woman and the item was very easy to put on and use. Instructions were good. The item came boxed well. The removal was easy, etc.

This topper is great, we purchased a new bed and mattress and it was hard. Hubby decided to get this and the difference is amazing, not soft but definitely not as hard as our new mattress, it kind of sinks you in but not to the point that it's soft works just right for us and we've had it for over 3 months. We love the cooling effect and it helped so much with my back after the new mattress, strong yet so comfortable.

This cover has saved me. I have a futon that currently I must sleep on and in-between the cushions there is a hard like metal bar and the cover is firm enough to keep me from feeling it. Firm, but not hard. Expanded within 5 hours or less after removing it from the box. Quality. Seams and material are quality. Material is like a mattress. Zipper to remove and wash is good. Cool vs. warm. It is not summer yet so I don't know how cool it will be. However, I am overweight, and I don't sink far into it.
