Cooling Mattress Topper for Hot Sleepers (Queen)

If you wake up warm, the cover and the loft of a topper both matter. Ours use a breathable bamboo viscose cover, and the lighter 550 GSM option keeps you closer to the surface.

Why a topper can sleep warm, and what helps

Heat builds up when a surface traps air and sinks you into it. Two things drive that: the fabric you lie on and how deep you sit in the fill. A cover that breathes lets warm air move away, and a lower loft means less of your body is surrounded by padding.

Our toppers use a bamboo viscose and polyester cover. Bamboo viscose has a smooth, silky hand and breathes well, so it feels cooler to the touch than many plain polyester covers.

550 GSM for warm sleepers

The 550 GSM topper is our medium plush option. The fill is lighter, so you stay on top of the surface rather than sinking in. That is the usual preference for people who run warm, because less of you is wrapped in padding.

It also fits a wide range of beds, with a deep pocket for mattresses 8 to 20 inches deep, so a thicker memory foam or hybrid mattress is no problem.

When 1000 GSM still makes sense

The 1000 GSM topper uses the same bamboo viscose cover, so it also breathes. It simply has a lot more fill and a deeper, more cushioned feel. If your mattress is very firm and you want a thick pillow top, it is a fair choice even if you sleep warm. If staying cool is the top priority, start with 550 GSM.

Small habits that keep a bed cooler

Wash the topper from time to time. Our toppers are machine washable on a gentle cycle at 30°C or cooler, then tumble dried with no heat. Shake the fill out afterward so it stays fluffy and airy, and give it 24 to 48 hours to recover its loft.

Pair the topper with breathable sheets and a lighter blanket. Our guide to cooling toppers goes through what to look for in covers and fills.

Cooling toppers compared

The cover is identical, so the loft is the main thing that changes how warm the bed feels.

Questions about this topper

Is there a cooling mattress topper in queen size?

Yes. Both of our queen toppers use a breathable bamboo viscose cover. The 550 GSM is the lighter, cooler-feeling pick, and the 1000 GSM is the deeper cushion.

What is the best mattress topper for hot sleepers?

A breathable cover and a lower loft help most. Our 550 GSM topper pairs a bamboo viscose cover with a medium plush fill, so you sit on top of it rather than in it.

Is bamboo viscose breathable?

Yes, it is a smooth fabric that breathes well and lets warm air move away from the body. Our toppers combine it with polyester in the cover.

Does the 1000 GSM topper sleep hotter than the 550 GSM?

It has more fill, so you sink in deeper and more of your body is surrounded by padding. The cover is the same bamboo viscose blend. If you sleep warm, the 550 GSM is the safer pick.

Will a topper make my mattress sleep hotter?

It can if the cover or fill traps heat. A breathable cover and a medium loft reduce that. Starting with 550 GSM is a sensible choice if heat is your concern.

Can I put a cooling topper on a memory foam mattress?

Yes. The 550 GSM pocket fits mattresses 8 to 20 inches deep and the 1000 GSM pocket goes up to 21 inches, so thick foam mattresses are covered.
