Great Mattress

So far, this mattress has been wonderful. Firm but appropriately cushioned by the gel top layer. An incredible bargain compared to similar mattress priced 2-3 times higher.

Extremely firm, great for true back pain sufferers

I purchased this bed as the extra firm hybrid. I love the firmness and level of comfort that it provided to me. I had never had a foam mattress and it was warmer than I preferred, but I'm also in menopause. I did end up returning it for a full refund after 90 days because it was not working well with my Helix bed frame. When they say extra firm they mean it! though that was a big benefit for my back it was not such a great benefit for my Helix frame. It struggled putting it up and back down again and fell out of the frame, at the top, often. I believe this extra firm was simply too heavy for the Helix to handle. I see no fault whatsoever with the mattress. Had I not been using it with an adjustable bed I would have happily kept it and slept on it as I won't be menopausal forever! I wouldn't recommend the extra firm hybrid for an adjustable bed but I think perhaps firm or below would work just fine. If you are looking just for an extra firm mattress I would recommend this 100%! As someone with serious disabilities stemming from my back, spine and neck I was so happy and comfortable with the extreme firmness of this mattress. It's not for sissies, days 8 to 14 I had a lot of hip pain but as someone who has always purchased extra firm mattresses that is not uncommon as your spine gets used to your new bed. If you like it smooshy and cushy extra firm is not for you. However if your orthopedist has ever suggested you put a piece of plywood under your mattress you won't need that with this extra firm! It is better than I can express here. It seems to me that an extra firm is getting harder and harder to find nowadays so I do highly recommend this mattress just not with an adjustable bed frame.

Hello Margaret! Thank you so much for this detailed and honest review. We're glad the extra firm support worked well for your back, spine, and neck, and we appreciate your note that its weight and firmness make it a poor match for an adjustable frame — that's helpful guidance for future shoppers. We value your recommendation for anyone seeking a true extra firm mattress. Warm regards, GREOO Support Team

It's not extra firm quality but I'm sleeping good. Good value for the buck!
