Take a look at our rating below before deep-diving into our full REM-Fit 500 pillow review.


What does sleeping on the REM-Fit 500 Cool Gel pillow feel like?

Sleeping on the REM-Fit 500 Cool Gel pillow provides a specific, adaptive feel, notably different from a standard pillow.

Its gel-infused memory foam moulds to the body's contours, cradling the head and effectively distributing weight to cushion pressure points along the head and shoulders.

You can see this so-called memory effect in the images below:

This design promotes excellent neck and spinal alignment, preventing uncomfortable dipping and offering a consistently stable foundation.

We found the pillow maintains a good level of firmness - neither too hard nor too soft - which contributes to significant relief for many, particularly those with chronic neck pain, as it holds its shape without flattening out.

The pillow’s design makes it highly suitable for various sleeping positions.

  • For back sleepers, the foam fills the natural curve between the head and mattress, ensuring good spinal alignment.
  • Side sleepers benefit from its loft and contouring, keeping the neck perfectly in line with the spine.
  • While it may initially feel slightly high for some stomach sleepers, the memory foam’s ability to compress and gently recover its shape means it can still offer comfort for shorter periods. But this is the one position we wouldn't recommend the pillow for. A fully customisable pillow where you can really adjust the loft, like the Emma Premium Pillow or the Simba Hybrid Pillow, would be a better option. It's sometimes also recommended that stomach sleepers should sleep without a pillow entirely.

This adaptability contributes to the REM-Fit pillow's reputation as a versatile, all-rounder choice for a broad range of sleepers, providing consistent support throughout the night.

Can the REM-Fit 500 Cool Gel pillow help alleviate neck and shoulder pain for side sleepers?

REM-Fit pillow's cooling performance and breathability

The REM-Fit 500 Cool Gel pillow is specifically designed to keep you cool and supported throughout the night.

Its innovative materials and structure work together to manage heat, wick away moisture, and offer steady airflow for optimal temperature regulation.

The pillow's core is viscoelastic polyurethane foam, infused with cool gel - this cool gel actively draws heat away from your head, providing a refreshing and comfortable sleep surface.

The effect is noticeable even through a standard pillowcase, offering a constant, mild cooling sensation.

This helps the pillow maintain a comfortable temperature for longer, especially during warmer nights, and many users report not waking up feeling hot or sweaty.

Further enhancing breathability, the outer cover is made with Re-Ax® fibres.

These ultra-light, stretchy fibres allow air to pass through freely, preventing heat build-up, and they also possess strong moisture-wicking ability, pulling sweat away from your skin to keep you dry.

This combination of features allows the REM-Fit 500 to efficiently absorb and release heat, and it's often rated as one of the best pillows for cooling among gel-infused memory foam options.

How does the REM-Fit 500 pillow compare to traditional memory foam pillows?

Traditional memory foam pillows are known for pressure relief but they often trap heat. 🔥

The REM-Fit 500 significantly improves on this by adding a cool gel layer and a sweat-wicking outer cover with mesh inserts, which together dramatically increase airflow.

This design provides both active cooling and a "just right" supportive, springy feel, resulting in a fresher sleep experience compared to often warmer and less breathable traditional memory foam pillows.


REM-Fit 500 Cool Gel Pillow design & construction

The REM-Fit 500 Cool Gel Pillow combines memory foam with cool gel technology for enhanced comfort.

Its core is made from viscoelastic polyurethane foam, known for its pressure-relieving properties, and a vital cool gel pad sits atop the foam, regulating temperature and drawing heat away from your head.

Key materials:

- Filling: Viscoelastic polyurethane foam with embedded gel powders

- Outer Cover: 40% Lyocell (from Tencel), 60% Polyester

- Inner Cover: 100% Cotton

This unique design makes the pillow ideal for those who overheat and ensures your head, neck, and shoulders remain well-aligned across all sleeping positions.

The REM-Fit 500 Cool Gel pillow has dimensions of 64 x 40 x 12 cm and weighs approximately 2.5kg.

Can you wash the REM-Fit 500 Cool Gel pillow?

Understanding how to clean your pillow is vital for hygiene and longevity.

Luckily, the REM-Fit 500 Cool Gel pillow comes with very specific washing instructions:

  • Outer cover: Removable and machine-washable at 40°C
  • Memory foam filling: Not washable; sponge-clean only

Memory foam, in fact, should never be washed or soaked, as the water and agitation can damage the foam and reduce its support. 🙅

But with the removable and machine-washable outer cover, you can ensure your REM-Fit pillow stays cleaner and fresher for longer.

We'd recommend using a mild detergent and allowing the cover to air dry fully before putting it back on the pillow.

What does the REM-Fit 500 Cool Gel pillow cost?

The REM-Fit 500 Cool Gel pillow is relatively well-priced when compared to other high-quality options that have made our best pillow in the UK list.

And while more expensive than pillows you'll get at Silentnight or IKEA, for example, you'll definitely be investing in a pillow of much higher quality.

You'll occasionally even find REM-Fit pillow discount codes, and you can even save up to 10% on your purchase if you get the pillow together with a REM-Fit mattress.

REM-Fit pillow delivery & trial conditions

REM-Fit offers free delivery within 1 - 3 business days across the UK, with pillows arriving conveniently boxed.

Our pillow arrived wrapped in a re-usable carry bag, placed in a larger transport box.

Interestingly, unlike many other memory foam pillows, like the Derila Ergo Pillow and the Brightr Sleep pillows, the REM-Fit pillow was not compressed.

While this takes more space during delivery, it also means there's no potential damage to the pillow and you're unlikely to experience any off-gassing.

Unlike REM-Fit mattresses, the pillows do not currently include a long home trial or free returns after use.

This means you won't have a chance to change your mind if you're not happy with your purchase.

Generally, we'd prefer pillows with home trials, like the Panda Hybrid pillow or the Emma Original pillow.

But, considering the high quality of the REM-Fit pillow, it's unlikely that you'll be able to fault it if you're a back or side sleeper after that memory foam feel.

The REM-Fit 500 Cool Gel Pillow does come with a 5-year guarantee against defects, provided it’s used with a pillow protector, covering problems in materials or workmanship.

Should you buy the REM-Fit 500 Cool Gel pillow?

The REM-Fit 500 Cool Gel Pillow stands out for its blend of advanced cooling and adaptive support.

Its gel-infused memory foam promotes excellent spinal alignment and consistent pressure relief for various sleeping positions, while the cooling technology allows for a better temperature regulation.

For anyone seeking a pillow that stays cool and holds its shape throughout the night, together with the support of memory foam, the REM-Fit 500 pillow is an excellent choice.

Frequently asked questions

  • What are the comparative benefits of the REM-Fit 500 pillow versus the REM-Fit Snow pillow?


    Both REM-Fit pillows are made with premium memory foam. 

    • The REM-Fit 500 Cool Gel pillow focuses on gel-infused cooling and even temperature control.
    • In contrast, the REM-Fit Snow pillow has a “cold to the touch” surface, thanks to a Nordic chill fabric and Tencel fibres that help wick heat and sweat even faster. 

    The Snow Pillow is designed to dissipate heat ten times quicker than cotton, making it a strong choice for those who prefer an extra cool feel.

  • Is there a significant difference between the REM-Fit Cool Gel and the REM-Fit Bamboo Charcoal pillows?


    The REM-Fit Cool Gel pillow uses gel-infused memory foam to give balanced, adaptive support and cooling. 

    The REM-Fit Bamboo Charcoal pillow uses bamboo charcoal-infused foam, which is naturally hypoallergenic, helps manage odours, and absorbs moisture. 

    Both pillows offer good support and pressure relief, but the Bamboo Charcoal version is particularly suited to allergy sufferers and those concerned about odours.
