Is Your Mattress Making You Hot at Night? Here’s How to Tell

We all know the feeling: you climb into bed, ready for a decent night’s sleep… but within half an hour you’re tossing, turning, and peeling the covers off because you’re overheating. Sound familiar? The culprit might not just be the weather—it could be your mattress.

Here’s how to spot the signs and what to do about it.

Signs Your Mattress Might Be Making You Overheat

1. You Wake Up Sweaty (Even in Cooler Weather)
   If you’re waking up sticky and damp even when the nights aren’t scorching, it’s often your mattress trapping heat.
2. Your Bed Feels Warm to the Touch
   Memory foam is notorious for holding onto body heat. If your mattress feels warm even after you get out of bed, it’s not letting air flow properly.
3. You Toss and Turn More in the Night
   Overheating triggers restlessness. If you can’t settle or keep waking up, your body’s probably trying to cool itself down.
4. Your Feet Feel Like They’re on Fire
   “Red hot feet” are one of the biggest giveaways. If you’re sticking your feet out of the covers every night just to cool down, your mattress is trapping too much heat.
5. Your Partner Sleeps Fine, But You Don’t
   Some mattresses respond differently to body weight and heat. If one of you sleeps like a baby and the other’s roasting, it’s a red flag.

Why Some Mattresses Make You Too Hot

• Dense foams: They mould to your shape but don’t allow air to circulate.
• Older mattresses: Springs wear out and airflow reduces over time.
• Cheap fillings: Synthetic fibres can trap heat, unlike natural materials.

Cooler Options That Make a Difference

• Natural Fillings: Wool, cotton, and silk wick away moisture and keep you cool in summer, warm in winter.
• Hybrid Mattresses: A mix of springs + foam gives you support and airflow.
• Breathable Designs: Modern mattresses often feature airflow channels to prevent heat build-up.

At TV Beds Northwest, our Sleepeezee Wool Collection is a customer favourite for exactly this reason—natural fillings that regulate temperature all year round.

Quick Fixes While You Wait to Upgrade

• Swap to a lightweight duvet (4.5 tog or lower in summer).
• Try breathable cotton or linen bedding.
• Add a cooling mattress topper as a short-term solution.
• Keep your feet cool with a bowl of cold water before bed—old school, but it works!

The Bottom Line

If you’re waking up in a sweat every night—or sticking your “red hot feet” out of the covers just to survive the night—don’t just blame the British summer. It could be your mattress holding onto heat. The good news? With the right materials and design, you can enjoy cooler, deeper sleep without tossing and turning.
