Frequently asked

Is this mattress hypoallergenic or dust mite resistant?
All mattresses gradually collect allergens through normal use. A mattress encasement can help create a barrier between you and the mattress surface.

• Encase the whole bed — mattress, pillows and quilt — for full coverage where you sleep. Shop the dust mite encasement range.
• Short on budget? Start with the mattress. A dust mite mattress protector covers the biggest surface for the lowest spend — then add a pillow protector and quilt protector later.
• Backed by research. A 2003 clinical trial found mattress and pillow encasings significantly reduced dust mite allergen levels over 12 months.
• Get the full setup right. Our low-allergen bedroom guide covers encasements, washing and humidity in one place.

Managing a diagnosed allergy? Your GP or allergy specialist can advise on what's right for you.

What does "no-turn" mean?
No-turn mattresses are designed so you only need to rotate them head-to-foot for even wear, rather than flipping them over. The Firm Mattress is built to be used one side up.

How firm is 7.0?
On a 1-10 scale, 7.0 is a medium-firm feel — supportive without being hard. Slightly firmer than our 6.5 medium-firm options.

Will this fit a dust mite mattress encasement?
This mattress is 30cm deep, 137 × 190cm (Double). Encasements sized for 24–33cm Double mattresses will fit. Browse our mattress encasement range for current sizing.
