Reports of sagging, loss of support / excessive softening, and the development of body impressions are reported by at least 15% of owners. It should be noted, however, the top layer of the Leesa which appeared to be a cause of the problems was recently replaced, and this may help to improve durability / longevity going forward.

As is often the case with this category, the Leesa simply does not work for everyone. Common complaints include both that the mattress is too soft and that it is too firm, though the excessive firmness is more a more common criticism. If creating one perfect mattress that suits everyone seems too good to be true, it most likely is.
