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.
