Leesa Original Mattress

User feedback is sharply divided along timeline lines. During the 100-night trial, most users report genuine comfort — 'absolutely loved it,' 'very comfortable.' However, a recurring and alarming pattern emerges post-trial: the foam softens dramatically. One detailed side-sleeper account describes the mattress becoming 'so, so uncomfortable' over the course of a year, with the torso sinking several inches while legs and head don't, creating a painful sleeping angle. This user reports constant shifting, difficulty falling asleep, and regular nighttime waking. A stomach sleeper reported waking with sharp pain after 2 months. Back sleepers fare better. Multiple users compare Leesa unfavorably to Purple, citing Purple's hyper-elastic polymer as more durable and cooler. Cost is Leesa's most cited advantage over Purple. One user notes their older Leesa (with Avena foam) isn't as nice as newer LSA200 models. A 9-year owner reports developing back pain. UK/European users are stranded — Leesa ceased trading there, making returns impossible. Heat retention is a expressed concern for the all-foam construction.
