Question: I want to know the firmness of the mattress
Document: I don't feel the heat at all, possibly because the top layer was made of cool gel memory foam?When the mattress arrived, it took about 30 minutes for the mattress to expand to 13 inches, then it took a couple of hours for it to grow to 14 inches. When we rolled it out, my husband asked me which side was the length, and my answer was "I don't know". It looked like a square bed to me. It took us about 10 minutes to figure it out.
I remember feeling like I had slept eight hours after waking up after only two to use the restroom. I know this might seem corny, but we're so happy with the mattress that we actually ask friends and family who come over to lay down on it just to see how comfortable it is.The only real complaint I have is that when we first received the mattress, there was not an air tight seal and the mattress began expanding as soon as we opened the box; before we could get it properly placed.
(IF you compare this with FIRM mattresses)  The only &#34;feature&#34; I don't necessarily think is effective is the cooling layer. I've found myself waking up very hot even though it's 60 degrees in the room. Other reviewers for the queen sized version mentioned getting thin mattress toppers to help with the firmness and cooling, but isn't that what the top layer on this is for?Bottom Line:Back-Sleepers, you'll love itSide-Sleepers, give it some time, it does get better but you have to make it that far first.
Pros: Good price, firm enough for those with back pain, does not retain heat, conforms to bodyCons: So far...None.I bought this memory foam mattress because my 18 months twin girls want to snuggle in with me at bed time. The old queen size mattress was too small for the four of us.The next day I took a nap during the day and I slept like a baby for 3 hours straight, waking up feeling so refresh. The mattress is firm enough to straighten my spine, since I have back pain, but conforms to my body, especially when I'm on my side.
I do still get faint smells sometimes though. I've had this mattress for a month and am happy so far.
I was nervous about purchasing over the web. We both are very happy, and have no regrets. Just smells weird for the 1st couple of days. It feels like an expensive mattress.
Best to open windows. All this is definitely worth it!! !I also called the seller in California, he sent us two free Cool Breeze GEL Memory Foam pillows with the Mattress!
Great value on a good product. Everything as described. The seller was very responsive and accommodating to an issue from shipping (likely caused by the carrier's handling). They were extremely helpful and professional. I would recommend this product and the company to others looking for memory foam mattress.K.Jacobs
The old bed squeaked and shook a bit whenever I moved, but this one is pretty quiet and stable.I'm waiting for the odor to be completely gone so that my husband can join in with us during the weekend.So far we have had very good experiences with the mattress. I love it, looks like the twins also love it. I hope that the mattress can stand the test of time. I do think that it will.
I read the reviews from the non cool gel mattress since this one did not have a review and took a chance. I'm glad I did. I sleep all throughout the night and no soreness. It did come in a bundle that looked like a water heater, but it quickly went to its normal size. It did have the smell that others described, but it quickly went away. I definitely recommend it, it is worth it.
Answer: It's pretty firm without being rock solid.
