What a great buy! I placed the twin XL on top of an expensive mattress we bought that was sold to us by mattress firm, ended up being a fake medium (sales person assured us that it is in between plush and medium - it landed me in ER as a small built person who basically had me sleeping on a brick as far as my body is concerned resulted in musculoskeletal pain. I was told to sleep on it and it will get softer.) This mattress topper is an answer to my prayer - guided via an AI question and was provided as one of the 3 best options for my situation.
