i call customer support no return respinse. This is NOT A 4inch gel foam as i measured 2 inches. i purchased same topper that i enjoyed at a lower price nit realuzing os the same at a higher price! No loyalty to return call and paid over a hundred dollars more fir the same topper. if this is bought you are not getting 4 inches but its comfortavle i thought i would have more comfort with a thicker foam.
Appears to be OK. I have not used it yet & won’t for a few months; hard to determine how well I like it. I have a memory foam mattress which is packed away, but I sleep on a memory foam mattress, purchased through Groupon as well but not mine. The memory foam forms in areas where you tend to sleep the most; the reason why I purchase this gel form mattress top. Hoping it helps. 3 for doubts~
this gel foam unit does not come advertised with the support rating. i.e. firm, medium, soft etc. It arrived quickly. I let the foam and topper air out. When it was on the floor airing out i laid down on it. The foam has no support. I sink right to the hard floor. This should have a rating lower than soft. It is of no use vs a firm topper of 1-2 inch thickness. I purchased the most expensive unit 219 dollar vs 149 unit to get the best support and have no support. Don't waste your money on this. The foam density is no enough to support your body on what was shipped to me. And they say no returns. Very dissatisfied.
