Bests & Worsts Reviews from Amazon

After reading the reviews I opted in and purchased this mattress. From the description and other reviews I had thought that this was a a mid-firm mattress. However, after 2 months of use I noticed that the mattress sagged in the middle. I'm not a small person and at 180 lbs and 6 ft I assumed the depression was in bed frame, nope. After moving the mattress to the floor the depression was still just as visible and discernible when laying on the mattress on the floor. Flipped it over but nothing worked. As I had already missed the return date, I took my trusty fillet knife and peered in, like a magician, I had cut it in twade. Here are the measurements that I took of both the egg crate height and the total height to the tops of the egg crate. Side measurements taken 10 inches in from the edge and center measures are from center... First Picture, Side from bottom of mattress to egg crate peaks approx: 6.25 in. Second Picture, Center of mattress measuring from the bottom to the peaks approx: 5.75 in. Third pic. Center of mattress measuring only peak height of the egg crate approx: 1.75 in. Side measure of egg crate only 2.125 in. Adhering to the scientific method I made sure that the mattress was not used for one week and placed vertically on edge when measuring to nullify any anomalies caused by gravity or an uneven surface. These measurements are relatively close but if the foam has degraded that quick (3 month period) I can assure you that you will feel a drastic amount of sag in the mattress. If you have back problems I would not but this mattress. As such, I have purchased a different mattress from a local retailer and could not be happier with my choice to slice and dice this over priced piece of foam. Also, I used some of the foam to make a plush dog bed. Yes I'm out a chunk of money, but damn it fells good to be a Gangster ( addendum... Magician). Hope this is helpful. Cheers!
