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's a Bonnell spring mattress?
Bonnell springs are interconnected hourglass-shaped coils — a traditional, durable construction that gives a firmer, more supportive feel. They differ from pocket springs (individually wrapped, independent coils) in that the springs work as a single connected unit.

Is 16cm thick enough for an adult mattress?
16cm is a slim profile — well-suited to children's beds, bunk beds, guest rooms, or trundle beds. For an adult primary mattress with a deeper feel, see our 25cm, 30cm, and 34cm options in the mattress range.

Will this fit a dust mite mattress encasement?
This mattress is 16cm deep, 91 × 190cm (Single). Encasements sized for 18–24cm Single mattresses fit (with some slack). Browse our mattress encasement range for current sizing.

What sizes is this mattress available in?
This listing is the Single only. See our full mattress range for King Single, Double, Queen, and King.

How does it arrive?
Vacuum-rolled in a box for easy delivery and room access. Allow up to 24 hours after unboxing for the mattress to fully expand to its 16cm profile.
