Sleep & Beyond myTopper Review: A Washable Wool Mattress Topper That Stays Cool All Night
Most mattress toppers are made from foam. Memory foam, gel foam, egg crate foam. And they all do the same thing after a few months: trap heat and smell weird. The Sleep & Beyond myTopper takes a completely different approach. Its made from natural washable wool, and it stays cool in a way that foam just cant.
I wasn’t expecting much from a wool topper, honestly. Wool sounds warm. Like a winter thing. But merino wool is naturally temperature regulating, and sleeping on it feels different than sleeping on it sounds.
Why Wool Works Better Than Foam for Sleep
Foam toppers absorb your body heat and hold it. Thats why you start cool and wake up sweating at 3am. Wool does the opposite. It wicks moisture away from your skin and releases heat instead of trapping it. The myTopper uses natural merino wool thats been processed to be machine washable, which solves the biggest complaint people have about wool bedding.
The feel is different from foam too. Its not that sinking in feeling. Its more of a cushioned support, like sleeping on a thick, soft pad. If you like the cloud feeling of memory foam, this isn’t that. But if you wake up hot or find foam too soft, this is worth trying.
The Machine Washable Part Is a Big Deal
Most wool bedding says “dry clean only” and that alone scares people off. The myTopper is genuinely machine washable. You throw it in on a gentle cycle with cold water, tumble dry low, and its fine. I think this is the main reason to pick this over other wool toppers that need professional cleaning every time something spills.
After washing, the wool bounces back pretty well. Theres a slight loss of loft the first time but it recovers after a day or two of use. Not a big deal.
How It Sleeps Night to Night
The first night felt unusual just because its so different from foam. The surface has a bit of spring to it. By night three I was sleeping through without waking up sweaty, which was the whole reason I tried it. My partner runs warm and she noticed the difference even faster than I did.
One thing to know: it doesnt add a ton of cushion. If your mattress is too firm and you need serious padding, a 3 inch foam topper will do more. The myTopper adds comfort but its real job is temperature and moisture control. Think of it as a climate layer more than a softness layer.

Who This Is For
Hot sleepers. Thats the main audience here and Sleep & Beyond knows it. If you wake up overheated, kick off covers at night, or find that gel foam toppers stop being cool after a few weeks, the myTopper actually solves the problem instead of marketing around it. Wool regulates temperature naturally. Theres no gel beads or phase change material that stops working. It just works.
Also good for anyone who wants natural bedding without the hassle. Machine washable wool is rare and its the reason this topper stands out from the rest of the Sleep & Beyond lineup.
Common Questions
No, and that surprised me too. Wool regulates both ways. It keeps you warm when its cold and cool when its hot. In summer it actually felt cooler than my old gel foam topper.
Wool is naturally antimicrobial so you dont need to wash it often. Every 3 to 6 months is fine unless something spills. Spot clean small messes.
Yes. It sits on top of your mattress and has elastic straps on the corners to hold it in place. Works on mattresses up to about 18 inches deep.
