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.

REM-Fit 400 Memory Foam Crumbed Pillow
From independent research • UK sleep studies
Most people are sleeping on a pillow past its replacement date.
The average UK adult keeps a pillow for 3.2 years - more than double the 1-2 year window recommended by sleep experts. As a pillow ages, its support degrades and allergen levels rise. The 400 Crumbed Pillow's memory foam crumbs and Re-Ax cover maintain consistent support and breathability across the recommended replacement window.

  • Memory foam crumbs - contoured support that moulds to your shape
  • Aids correct spinal alignment - excellent pressure relief for head and neck
  • Re-Ax fibres - absorb excess heat and wick sweat away from the body
  • Ultra-light, stretchy, durable fabric - comfortable against the skin

The REM-Fit 400 Memory Foam Crumbed Pillow uses contoured memory foam crumbs rather than a single solid block, giving support that moulds to the shape of your head and neck while staying breathable. Re-Ax fibres in the cover absorb excess heat and wick sweat away from the body, so the pillow stays comfortable even on warmer nights.

Who is it for?

Suited to anyone who wants the support of memory foam with a softer, more adaptable feel than a single solid foam block. The crumbed structure also makes it more breathable than traditional moulded memory foam.

What makes it different?

Because the foam is broken into crumbs rather than poured as one solid piece, the pillow moves and adjusts with you more naturally, while still keeping the pressure-relieving properties of memory foam. Combined with the Re-Ax cover, it sleeps cooler than a standard solid memory foam pillow. Pairs well with any REM-Fit hybrid mattress for a complete sleep setup.

Frequently asked questions

What is a crumbed memory foam pillow?+
It is a memory foam pillow filled with foam crumbs rather than a single solid block. The crumbs move and adjust with you, so the pillow moulds to the shape of your head and neck while keeping the pressure relief memory foam is known for, and it stays more breathable than a solid foam block.
Is a crumbed foam pillow better than a solid memory foam pillow?+
For many people, yes, if you want a more adaptable feel. Because the foam is crumbed rather than poured as one piece, it adjusts to your position more naturally and sleeps cooler than a solid block, while still supporting the head and neck. A solid memory foam pillow holds a fixed shape, which some sleepers prefer; the crumbed version is the more flexible, breathable option.
How often should you replace your pillow?+
Sleep experts recommend replacing a pillow every one to two years, but the average UK adult keeps theirs for over three. As a pillow ages its support breaks down and allergens build up, so if yours is past the two-year mark it is worth replacing. The 400 Crumbed Pillow's foam crumbs and Re-Ax cover are designed to hold their support and breathability across that window.
Does the 400 Crumbed Pillow sleep cool?+
It is designed to. The Re-Ax fibres in the cover absorb excess heat and wick sweat away from the body, and because the foam is crumbed rather than solid it allows more airflow, so it sleeps cooler than a standard solid memory foam pillow.
What is the difference between the 400 Crumbed Pillow and the 500 Cool Gel Pillow?+
Both are memory foam, with different strengths. The 400 Crumbed Pillow uses foam crumbs for a softer, more adaptable feel that moulds to you. Our Good Housekeeping Winner 2026 500 Cool Gel Pillow uses a solid gel-infused core built around active cooling and spinal support. Choose the 400 for an adjustable, breathable feel, or the Cool Gel if cooling and firmer support are your priority.

  • 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.

  • Bamboo charcoal infused memory foam - cutting-edge cooling and odour control
  • Naturally hypoallergenic - ideal for allergy sufferers
  • Regulates temperature and moisture - helps absorb odours overnight
  • Dust mite resistant - natural bamboo properties
  • 5-year guarantee - against defects in workmanship or materials
  • Choice of two depths - 8cm low depth or 12cm high depth

The REM-Fit Bamboo Charcoal Pillow uses cutting-edge bamboo charcoal infused memory foam, a fabric that's naturally hypoallergenic and helps regulate temperature, moisture and odours through the night. The bamboo properties also make it naturally resistant to dust mites, which makes it a sensible choice for allergy sufferers.

Who is it for?

Suited to allergy sufferers and anyone who wants a natural, hypoallergenic alternative to standard memory foam. The choice of depths also means it suits a wider range of sleeping positions and neck heights than a single fixed loft pillow.

What makes it different?

The charcoal infusion gives this pillow active odour and moisture control on top of the usual benefits of memory foam, while the bamboo properties add natural dust mite resistance. Offering two depths also lets you choose the loft that best matches your sleeping position, rather than a one-size-fits-all approach. Pairs well with any REM-Fit hybrid mattress for a complete, allergy-conscious sleep setup.

Frequently asked questions

Are bamboo charcoal pillows good for allergies?+
Yes. Bamboo is naturally hypoallergenic and the charcoal-infused foam resists dust mites, which matters because pillows are one of the main places dust mites live and around 12 million UK adults have a dust mite allergy. The dust mite-resistant cover and natural bamboo properties make it a sensible choice for allergy sufferers and anyone with sensitive skin.
What does the bamboo charcoal actually do?+
The bamboo charcoal is infused into the memory foam, where it helps regulate temperature and moisture and absorb odours through the night, on top of the contouring support memory foam is known for. The natural bamboo properties also give it resistance to dust mites.
Should I choose the 8cm or 12cm depth?+
Choose the depth to match how you sleep. The 12cm high depth suits side sleepers, who need more loft to keep the neck aligned with the spine, while the 8cm low depth suits back and front sleepers who need less height. If you move between positions through the night, the higher depth is usually the safer choice.
What is the difference between the Bamboo Charcoal Pillow and the 500 Cool Gel Pillow?+
Both are memory foam pillows with different priorities. The Bamboo Charcoal Pillow is built around natural, hypoallergenic materials with odour and moisture control, ideal for allergy sufferers. Our Good Housekeeping Winner 2026 500 Cool Gel Pillow focuses on active cooling through gel-infused foam. Choose the Bamboo Charcoal for hypoallergenic, odour-resistant comfort, or the Cool Gel if cooling is your priority.
Does the Bamboo Charcoal Pillow keep you cool?+
It helps. The bamboo charcoal infused foam is designed to regulate temperature and wick moisture rather than trapping heat the way standard memory foam can, and 84% of our shoppers say temperature regulation matters to them. For dedicated cooling our Snow and Cool Gel pillows go further, but the Bamboo Charcoal balances cooling with its hypoallergenic and odour-control benefits.

  • Nordic chill fabric - cold to the touch from the moment you lie down
  • Tencel fibres - wick away moisture and heat through the night
  • Dissipates heat 10x faster than cotton - noticeably cooler sleep surface
  • Cools effectively through a pillow case - keeps working even when covered
  • Premium Visco memory foam filling - supportive, pressure-relieving feel

The REM-Fit Snow Pillow uses Nordic chill fabric and Tencel fibres to wick away moisture and heat, dissipating warmth up to 10 times faster than cotton. Combined with a premium Visco memory foam filling, it stays cold to the touch even through a pillow case, making it one of the cooler options in the REM-Fit pillow range.

The Cooling Pillow Engineered to Stay Cold All Night

Suited to hot sleepers and anyone who struggles with overheating overnight. The combination of Nordic chill fabric and Tencel fibres makes this one of the more aggressively cooling pillows in the range, rather than just a standard breathable cover.

What makes it different?

Most cooling pillows rely on breathable fabric alone, but the Snow Pillow's Nordic chill fabric is genuinely cold to the touch, and continues working even with a pillow case on top. Paired with Visco memory foam, you get active cooling on top of the usual pressure relief benefits. Pairs well with any REM-Fit hybrid mattress for a complete, temperature-regulated sleep setup.

Frequently asked questions

Do cooling pillows actually work?+
Yes, though it depends on the design. The Snow Pillow uses Nordic chill fabric and Tencel fibres to draw heat and moisture away from your head, dissipating warmth up to 10 times faster than cotton, so the surface stays cooler for longer instead of trapping heat like a standard pillow. It is cold to the touch from the moment you lie down and keeps working even with a pillow case on top, backed by our 100-night trial so you can test it risk-free.
Is there a pillow that stays cold all night?+
The Snow Pillow is built for exactly this. Its Nordic chill fabric is genuinely cold to the touch and, paired with heat-wicking Tencel fibres, resists the warming that affects ordinary pillows through the night.
What is the difference between the Snow Pillow and a gel cooling pillow?+
Both keep you cool, in different ways. The Snow Pillow focuses on staying genuinely cold through the night with Nordic chill fabric and Tencel fibres over a Visco memory foam core. Our Good Housekeeping Winner 2026 500 Cool Gel Pillow pairs cooling gel with memory-foam support. Choose the Snow Pillow if cold is your priority, or the Cool Gel Pillow if you want cooling plus contouring support.
What does the Snow Pillow feel like?+
It has a supportive, pressure-relieving feel from its premium Visco memory foam filling, with the cooling Nordic chill surface on top. It suits hot sleepers who want memory-foam support without the heat build-up that foam can sometimes cause.
Is it suitable for hot sleepers?+
Yes. The Snow Pillow is one of REM-Fit's most aggressively cooling pillows, designed for hot sleepers and anyone who flips to the cool side of the pillow at night. It comes with free UK delivery, 0% finance options and a 100-night trial.
