Overview
A king-size comforter built for hot sleepers, with a Q-max cooling rating above 0.45 and a 7cm hollow sweat-zone design meant to cut the stuffiness of a standard down comforter. A 31% Tencel blend fill is added to help manage moisture through the night.
Most of the marketing here leans on lab metrics rather than lifestyle claims, which helps: a stated Q-max above 0.45 and a claim of 4 times more breathability than an unnamed baseline are specific enough to compare against other cooling comforters. The catch is that Bedsure frames the ideal comfort zone narrowly, around 73-77F in an air conditioned room, so buyers in hotter or unconditioned bedrooms may not see the same result.
- 7cm hollow sweat-zone channel design
- 31% Tencel fill blended into filling
- 102 x 90 inch king comforter size
- Machine washable, retains coolness per seller
Who it's for
Suits hot sleepers or night-sweat sufferers with a king bed and a room that stays around 73-77F. Cold sleepers or anyone without AC may find it underwhelming.
Strengths and trade-offs
Drawn from this product's published specifications.
- Q-max cooling rating measured above 0.45
- Tencel blend fill helps manage moisture
- OEKO-TEX certified fabric, free of harmful chemicals
- No owner reviews yet on real-world cooling
- Seller targets a narrow 73-77F AC range
Performance notes
The comforter's Q-max rating measures how fast the fabric surface pulls heat away from skin on first touch, which is the metric behind the cooling claim rather than active temperature control. The 7cm hollow channels at sweat-prone zones and the Tencel-blend fill work together to move moisture away from the body rather than trapping it against the comforter's outer shell.

What size is the Bedsure CoolOxy comforter?

Does the Bedsure CoolOxy work without air conditioning?
