What sleepers mention most
Feedback, grouped by what it's about.
4.9 · 235 comments summarized
Sleepers who run warm most often mention waking without the heavy, overheated feeling they had on their previous mattress.
“The first mattress that actually sleeps cool for me.”
“No more kicking the covers off at 2am — the surface just doesn't hold heat.”
Summaries are drawn from early Linden customer feedback collected during the 120-night trial. Verified third-party reviews will replace this module as the program scales.
