Cool Gel Memory Foam & Pocket Spring Mattress – Medium-Firm | Queen

The Giselle Bedding Tiberius Series is a 30cm-thick Queen mattress combining a pocket spring system with cool gel infused memory foam. The medium-firm feel suits a wide range of sleep preferences, with a 6-turn coil system and high-density foam base providing consistent support and stability.

The independent pocket coils help reduce motion transfer for shared sleeping spaces, and the breathable bamboo knitted fabric cover supports airflow. The mattress arrives vacuum-rolled and expands to full shape within approximately 24 hours of unpacking.

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.

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 Tiberius Series uses cool gel as its comfort layer over a pocket spring core. Real-world cooling depends on bedding choice, room temperature, and personal sleep environment.

What's a pocket spring mattress?
Pocket springs are individually wrapped coils that move independently. Compared with traditional Bonnell springs (interconnected coils), pocket springs offer more localised support and reduced motion transfer between sleepers, which makes them well suited to couples.

Will this fit a dust mite mattress encasement?
This mattress is 30cm deep, 153 × 203cm (Queen). Encasements sized for 24–33cm Queen mattresses fit. Browse our mattress encasement range for current sizing.
