If you wake up sticky at 3am even with the fan on, your mattress may be part of the problem. In Singapore’s warm, humid weather, a mattress that traps body heat makes it harder to fall and stay asleep. The good news: the right materials make a real difference. Here’s what makes a cooling mattress work, which of ours sleep coolest, and simple ways to keep your bed cooler.
Why some mattresses sleep hot
Your body sheds heat through the surface you lie on. A mattress sleeps hot when that heat has nowhere to go:
- Dense foam with no airflow. Traditional memory foam moulds closely around you, which feels lovely but holds warmth against your body.
- Sinking in too deep. The more you sink, the more of your body is wrapped in material, and the less air reaches your skin.
- Thick, non-breathable covers and toppers. A synthetic cover or a plastic-backed protector can undo a breathable mattress underneath.
Humidity makes all of this worse. When the air is already damp, sweat evaporates slowly, so you feel hotter at the same temperature.
What makes a mattress sleep cool
| Feature | Why it helps |
|---|---|
| Pocket springs | Open space between the coils lets air move through the mattress |
| Natural latex | Naturally breathable and springy, so you rest on it rather than sink into it; perforated latex adds vents for airflow |
| Gel memory foam | Gel draws heat away from the body better than plain memory foam |
| Cool-touch cover | Fabrics like ice silk, SnoWeave™ and bamboo knit feel cool to the touch and breathe better than standard covers |
| Supportive firmness | A medium firm to firm feel keeps more of your body on the surface, where air can reach it |
The coolest mattresses combine several of these: springs for airflow, latex or gel foam for comfort, and a cool-touch cover on top.

Nuloft Luxe: our cooling hybrid
The Nuloft Luxe was designed for hot, humid nights. Its SnoWeave™ fabric feels cool the moment you lie down, and the gel memory foam and breathable natural latex beneath it help heat escape rather than build up. Five-zone pocket springs and a layer of micro springs keep air moving and support your lower back and hips.

5 more ways to sleep cooler
- Choose breathable bedding. Cotton and natural fibres breathe better than polyester. Browse our bedsheet sets.
- Check your mattress protector. A thick, plastic-backed protector traps heat. Choose a breathable, waterproof one from our mattress protectors.
- Skip the extra topper. A thick foam topper on a cooling mattress adds back the heat the mattress was designed to release.
- Keep air moving. A ceiling fan over the bed helps sweat evaporate, and lets you set the air-con a degree or two higher.
- Air the mattress. Pull back the sheets for an hour in the morning so moisture from the night can escape.

FAQ
What is the best mattress for Singapore’s hot weather?
A hybrid mattress that combines pocket springs with natural latex or gel memory foam and a cool-touch cover. The springs let air flow, and the latex or gel helps heat escape. The Nuloft Luxe and Nuloft Hybrid are both built this way.
Is memory foam hot to sleep on?
Traditional memory foam can trap heat because it moulds closely around your body. Gel-infused memory foam, used in Nuloft mattresses, draws heat away better, and pairing it with latex and springs adds airflow.
Are spring mattresses cooler than foam mattresses?
Generally, yes. The open space around pocket springs lets air move through the mattress, while an all-foam mattress has less room for air. A spring-free mattress can still sleep cool if it uses perforated latex and gel foam, like The Nuloft.
Is a latex mattress good for hot sleepers?
Yes. Natural latex is breathable and springy, so you rest on top of it rather than sinking in, which keeps more of your body exposed to air.
Does a mattress protector make you hotter?
It can. Protectors with a plastic or vinyl backing trap heat. Choose a breathable, waterproof protector so your mattress can still release heat.
