If you struggle to stay warm in bed, a memory foam mattress retains heat better than a spring mattress because the foam restricts airflow, effectively trapping your body heat in the top layer of the mattress to keep you warm.

When memory foam mattresses first came out in the '90s, heat retention was a blessing and a curse since heat retention is bad on hot nights. However, thanks to mattress design and material innovations, today's memory foam mattresses retain heat without making you sweat. The best of both worlds!
In addition to pure foam mattresses, hybrid mattresses with a memory foam layer and pillowtop mattresses are also excellent at retaining heat.
Below, we've listed the top five mattresses for heat retention, considering the need for heat dissipation on hot nights.
The Giltedge Beds Cool Memory 1000 Mattress is a fantastic option if you're on a small budget. It's a pure foam mattress with a 5cm memory foam top layer and a generous 15cm reflex foam base layer. The reflex foam delivers support and response, while the top layer of memory foam provides squishy comfort.
Uniquely, this mattress has temperature-sensitive fabric that reduces heat build-up and a quilted mattress cover for a luxury feel. In other words, it retains heat without making you sweat! An excellent option for divans and frames.
Silentnight 3 Zone Memory Mattress
Price: £349 king-size.
Feel Medium-soft.

Another budget-friendly option is the Silentnight 3 Zone Memory Mattress, which uses Silentnight's Miratex response foam below a 3cm memory foam layer. It's medium-soft with a luxury soft-touch quilted cover. The memory foam and knitted cover retain heat while the response foam absorbs movement for partner isolation.
Although it has no heat-dissipating technology, the Silentnight 3 Zone is exceptionally comfortable with a squishy feel. It's ideal for sink-in sleepers, with 3-zone support for spinal alignment and pressure relief. Also available as a 7-zone medium mattress.
The Shire Pennine Pillowtop Mattress has a foam pillowtop comfort layer that traps heat, with 5cm of memory foam and 4cm of soft foam. The support system has 1,000 pocket springs, but the foam layers above this retain heat brilliantly.
With a pillowtop mattress, you get a soft, squishy top layer and a firmer base layer that provides support. The Shire Pennine has a medium feel, squishy without that sinking feeling. The memory foam responds to your temperature and spreads your body weight evenly, giving you a warm, comfortable night's sleep.
Birlea Bliss Mattress
Price: £449 king-size.
Feel Medium.

Your body heat is retained in the foam, while a pocket spring base provides excellent support and response. As the name suggests, sleeping on this mattress is like sleeping on a cloud!
The clever use of foam is what makes this mattress great. The top layer, 2 x 2cm soft foam layers, and 2cm memory foam layer retain heat brilliantly without making you sweat, while a soft-touch cover provides a real luxury.
If you often wake with aches and pains in the morning then the Sleepeezee G2 Memory mattress is for you. The Softech springs contour the body providing optimum support while the Graphite memory foam layer prevents overheating for a restful sleep. The soft, sumptuous finish provides that luxury feel you've been missing, for the perfect sleep haven.
