REM-Fit 500 Cool Gel Pillow
From sleep research • peer-reviewed, NIH 2025
Most hot sleepers say overheating is what keeps them awake.
82.5% of hot sleepers in a peer-reviewed study reported trouble sleeping because they felt too hot. The head is one of the body's primary heat release points - the 500 Cool Gel Pillow's gel-infused memory foam is engineered to draw heat away from the surface and dissipate it through the night.

  • Good Housekeeping Winner 2026 - Best Memory Foam Pillow
  • Cool gel-infused memory foam - natural cooling effect throughout the night
  • Supports correct spinal alignment - excellent pressure relief for head and neck
  • Ultra-light, stretchy, durable fabric - comfortable against the skin
  • Removable, washable cover - simple to keep clean

The REM-Fit 500 Cool Gel Pillow won Good Housekeeping's Best Memory Foam Pillow award in 2026, thanks to cool gel-infused memory foam that supports correct spinal alignment while keeping you cool through the night. The ultra-light, stretchy outer fabric and removable, washable cover make it as easy to maintain as it is comfortable to sleep on.

The Cooling Gel Pillow That Keeps You Cool Without Losing Support

Suited to anyone who wants the contouring support of memory foam without the heat retention that often comes with it. The cool gel infusion makes it a good fit for hot sleepers who still want pressure relief.

What makes it different?

Standard memory foam pillows tend to trap heat against the head and neck overnight. The gel infusion in the 500 Cool Gel actively works to disperse that heat, which is what helped it win Good Housekeeping's award for best memory foam pillow. Pairs well with any REM-Fit hybrid mattress for a complete, award-winning sleep setup.

Frequently asked questions

Do cooling gel pillows actually work?+
Yes, when the gel is built into the foam rather than sitting as a surface layer. The 500 Cool Gel Pillow uses gel-infused memory foam that draws heat away from your head and neck and disperses it through the night, so you get the contouring support of memory foam without the heat build-up it usually traps. It won the Good Housekeeping Best Memory Foam Pillow award in 2026, and comes with a 100-night trial so you can test it yourself.
What is a gel-infused memory foam pillow?+
It is a memory foam pillow with cooling gel blended into the foam itself. Standard memory foam tends to trap heat against your head overnight, whereas the gel infusion actively disperses that heat while keeping the pressure-relieving, spine-aligning support memory foam is known for.
What is the difference between the Cool Gel Pillow and the Snow Pillow?+
Both keep you cool, in different ways. The 500 Cool Gel Pillow pairs cooling gel with memory foam for contouring support and pressure relief, ideal if you want cooling plus neck support. Our Snow Pillow focuses on staying genuinely cold to the touch through the night with Nordic chill fabric. Choose the Cool Gel Pillow for cooling plus support, or the Snow Pillow if cold is your single priority.
Is a gel pillow good for neck and spinal support?+
Yes. The 500 Cool Gel Pillow's memory foam core supports correct spinal alignment and relieves pressure on the head and neck, which is part of why it won its Good Housekeeping award. The gel keeps it cool without sacrificing that support.
Can you wash the Cool Gel Pillow?+
The pillow has a removable, washable cover that is simple to keep clean, so you can wash the cover regularly while the gel-infused foam core keeps its shape and support.

Cotton Mattress Protector

An unprotected mattress builds up allergens with every night of use.
Between 100,000 and 10 million dust mites can live in a used mattress - feeding on the dead skin cells you shed every night. A mattress protector is the only thing that stops sweat, skin and allergens penetrating the mattress itself. The Cotton Protector's breathable jersey knit fabric and Miracle Membrane barrier block allergens without trapping heat.

Frequently asked questions

Do I need a mattress protector?+
It is strongly recommended. A used mattress builds up sweat, skin cells and anywhere between 100,000 and 10 million dust mites over time, and a protector is the only thing that stops those reaching the mattress itself. It also keeps your mattress clean and helps protect your sleep trial and guarantee, since staining can void them.
Is the cotton protector waterproof?+
Yes. A Miracle Membrane barrier underneath the cotton blocks spills and stains from reaching the mattress, while the breathable cotton surface stays soft against the skin and does not trap heat the way some waterproof protectors can.
Can you wash the cotton mattress protector?+
Yes, it is machine washable, so it is simple to keep clean. Washing it regularly removes the sweat, skin cells and allergens that build up on the sleep surface, which is part of what keeps your mattress hygienic over time.
What is the difference between the Cotton, Bamboo and Tencel mattress protectors?+
All three use the same Miracle Membrane barrier; the surface fabric is the difference. Cotton is the breathable, everyday option. Our Bamboo Protector is naturally more breathable and hypoallergenic, a step up for allergy-conscious or warmer sleepers, and our Tencel Cool Protector actively wicks moisture for hot sleepers. Choose cotton for reliable everyday protection without paying for cooling technology.
Does it fit a deep mattress?+
Yes. It stretches to fit mattresses up to 35cm deep for a secure, snug fit, and comes in UK sizes from single up to super king. Just choose your size at the top of the page.

  • 60 individual pocket springs - responsive, supportive feel
  • Soft white fibre filling - cushions the springs for added comfort
  • Breathable mesh border - helps air circulate through the pillow
  • Ideal for side and back sleepers - supports correct spinal alignment
  • 5-year guarantee - against defects in workmanship or materials

The REM-Fit Deluxe Pocket Sprung Pillow uses 60 individual pocket springs encased in soft white fibre filling, giving an ultra responsive feel that's noticeably different from a standard foam or fibre pillow. The springs work with you as you move through the night, helping maintain correct spinal alignment whether you sleep on your side or your back.

Who is it for?

Suited to side and back sleepers who find foam pillows either too soft or too firm. The pocket spring construction gives a more responsive, structured feel that holds its shape under the weight of your head and neck.

What makes it different?

Most pillows rely on foam or fibre alone, but the Deluxe Pocket Sprung uses the same individually-encased spring technology found in pocket sprung mattresses. This gives it a bouncier, more breathable feel than foam, with springs that respond independently rather than compressing as a single block.

Pairs well with any REM-Fit hybrid mattress for a complete sleep setup.
