I had a cheap matress for years, the kind that take the shape of your body as the springs wear out under your favorite spot. I am not sure what was causing my headaches but really wanted to go firmer than I ever did before to slow the development of a body outline after I get out of it. I am not sure if this will deliver after a year or more but the first month has seemed to deliver a better night sleep on average than my previous junk bed, and the headaches have cleared up. I can't confirm the bed is responsible but I do believe my posture is much healthier throughout the night.I weigh 220 lbs give or take(take please) and with the 10in thick model it is super firm.For those who care about aesthetics(I don't because it is always hidden under fitted sheets) I would say it is much better looking than any of the Ollie's bargain mattresses I ever owned before or the cheap spring only ones I grew up with.It inflated and unrolled very easily and was quite enjoyable watching it do so! They recommend letting the springs and components as it is a hybrid bed, have 2 days to fully recover from the long compressed journey they had on the way to your home. I gave mine 24 hours as my measurements showed no noticeable change in size from the first hour to the same hour 24 hours later. I doubt that having done so would have made it softer, but please comment if you know otherwise or have any insight into how I could have compromised the quality of it by being impatient. Thanks and hope this helps others make the right choice for their own circumstances!My biggest concern after reading reviews of other mattresses in the same price range was that it wouldn't expand after arriving, especially since I ordered a less common size and I thought it was more likely to have sat in the package at the warehouse before being sent out. I was also wondering how an inner spring mattress would work being vacuum packed, but it rolled out smoothly and rose to normal height within the first hour. We use this as our daily couch/day bed. Together we weigh 300#s and do not have a problem with it "bottoming out" although it definitely squishes down. At night it's also the regular bed for my 160#, 6'4" son, and he has no complaints about it being too soft, but he does not have back issues. Your mileage may vary. After a month it's holding up to daily use without a sag or dip in the middle. I'll update if it starts to wear out, but otherwise am happy I chose this brand.I bought this in 2021 and by 2022 my mattress coils have collapsed on the majority of one side of the mattress. How do I contact the seller considering it's supposed to be under a 10 yr warranty?! I'm currently pregnant and can't sleep comfortably with one side dipped in.For the price it's is very comfortable, easy to set up, medium firm.I didn't expect much out of a boxed mattress so was pleasantly surprised at how comfortable it was. We'll only sleep on it a half dozen times a year so didn't want to spend a lot of money. It fluffed up well and I don't think it sleeps any different than our expensive mattress at home.This bed is literally the best bed ive ever ownedVery comfortable mattress top is very nice I would buy this againLove the mattress, so far. I hope it holds up
