I have ne'er really been the type to care what bed I slept on, because I can fall asleep anywhere but I always wake up in the middle of the night, I usually think it's a ghost playing tricks on me lmao but I found out not too long ago I have a mild case of scoliosis, so I thought hey, that's my back randomly hurts. Which it is part of the reason. So I got this memory foam mattress based off the reviews I've seen and literally, I no longer wake up randomly throughout the night, and my back doesn't hurt as much! It still does from time to time but I think that's because my scoliosis. It literally conforms to your body and seriously this is the best purchase I've made! It's a little firm, but my goodness it really shapes to you body once you lay in it! There really wasn't a smell when I received and it came SUPER FAST! Like I was mind blown by how fast it arrived, it was like 3 days after I purchased it!
