The mattress is AMAZING! I was sleeping on a temperpudic and waking up with horrible back pain every single night!!! I set up the mattress very easily and by myself! I suggest putting it on top of your bed to let it do its thing but mine pretty much took its shape right away. It still needed to fill out a bit on the corners so I did let it sit for 24 hours but it filled out perfectly! Also the cooling on the premium is amazing! Very cooling and cozy all at the same time! I ordered a bed cover for the mattress because I obviously don’t want to stain it but….it is preventing me from feeling the coziness of the nectar cooling so I may just take it off and return it and just be extra careful. Also for reference, I ordered the king size in premium. In the pictures you can see the top corners did not completely fill when first opened, i would say it took about 48 hours for those to completely fill out but it did end up filling out and it’s perfect on all corners now. I know this review is all over the place but in case this helps, I do have two herniated discs in my lower back and this mattress has helped me immensely. I was waking up in horrible pain and it’s been almost 3 weeks now sleeping on this mattress and I am pain free in the morning and most of the day and not waking up so stiff all over my body either! I also added the nectaroutlet.com pick up service and that was great as well. They took the old mattress at the time of delivering this one, they were really fast and it is much cheaper than paying another company to come do it for you and also very convenient! Oh and one last thing, I did not notice any smell when I opened the mattress at all!

Mattress sat unused for over 72 hours. Did not inflate all the way on right side. Its Higher in the middle than the sides and is super hard. I wake up sore!

*5 month update* I really love this mattress. I meant to update the review sooner. Minimal to no back pain and sleeping better than I had before. *2 week update* I've been sleeping on the mattress over 2 weeks now. I am happily surprised to say the more I sleep on it, the more I like it. I have a pars fracture at my L5 which leaves me with back pain quite often. This mattress has allowed me a better sleep than my previous which was a serta sleeper pillow top. *update* Removed the waterproof mattress cover I had on the mattress and did not have issues with overheating and night sweats. This was great advice from a friend that I hadn't thought of. I've always used a waterproof mattress cover but the advice was it might be preventing the 'cooling' benefits. Waited 72 hours to use... Overheated from mattress which led to night sweats while AC set to 65 degrees. I'm so disappointed with the hybrid mattress. Sitting on the mattress feels like you sink in which made me worry it wouldn't provide enough support but once you lay down and weight is distributed, it's better.
