Super Nice!

I received this Greoo Queen Size 12in Firm mattress in exchage for my honest review. The mattress came in a tightly sealed box with the mattress vacuum sealed. There was no odor in the box of within the mattress upon opening. I always open the mattress on the side and way to fit the frame. I have a metal frame that needs no box spring. It is a firm mattress amd has motion isolation, I love this because my husband is a tosser and he tosses and turns all night. There is no harmful chemicals used in production of this mattress which gives me peace of mind. This mattress was fully inflated within 2 hours even though the time says 48 hours. The mattress is worth every single penny! I highly recommend!

Hello anonymous! Thank you for your honest review of our Greoo Queen Size 12‑inch Firm mattress! We’re pleased there was no unpleasant odor out of the box, and that it worked perfectly with your box‑spring‑free metal frame. It’s wonderful the motion isolation helps with nighttime tossing and turning, and that it fully expanded in just 2 hours. Thank you for your strong recommendation. Sincerely, GREOO Support Team

nice!!

actually a very nice mattress much denser than I thought it would be I thought it would be more like a memory foam but it is very firm and solid which is good because then you don't just sink and you can use this as a standalone mattress and it is not a mattress topper it is the whole mattress itself just no springs. I hope that in the long run it holds up without saying in the middle it's so far so good I unrolled it out of the box it instantly started expanding and got pretty firm pretty quickly to almost full size. lay down on it for a while and read and it was very comfortable can't wait to use this from now on since my old mattress was horrible!
