Cool Gel Memory Foam Mattress 25cm | Single

The Giselle Bedding Belle Series is a 25cm-thick Single non-spring memory foam mattress with a multi-layer foam structure: a CertiPUR-US certified cool gel memory foam top layer, egg-shaped foam middle layer, and 16cm high-density support foam base. The Belgian knitted fabric cover is removable via zip and machine washable.

The layered foam design helps minimise motion transfer for reduced partner disturbance, and a non-slip base keeps the mattress stable. The mattress arrives vacuum-rolled and expands to full shape within approximately 24 hours of unpacking.

Not suitable for children under 3 years of age.

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 CertiPUR-US certification?
CertiPUR-US is an independent certification program for flexible polyurethane foam. It indicates the foam has been tested for content (free of certain substances like ozone-depleting chemicals, formaldehyde, and certain phthalates), emissions, and durability. The cool gel memory foam top layer in this mattress is CertiPUR-US certified.

Is cool gel memory foam better for hot sleepers?
Cool gel infused memory foam is designed to dissipate heat more effectively than standard memory foam. The Belle Series uses cool gel as its top layer. Real-world cooling depends on bedding choice, room temperature, and personal sleep environment.

Will this fit a dust mite mattress encasement?
This mattress is 25cm deep, 91 × 189cm (Single). Encasements sized for 24–33cm Single mattresses fit. Browse our mattress encasement range for current sizing.
