Memory Foam Mattress Topper | 4cm | Bamboo Cover | King

A 4cm high-density memory foam mattress topper with a removable bamboo jacquard cover, designed for people who want gentle pressure relief and body-contouring support with a lower profile. According to the manufacturer, this topper is hypoallergenic.

At 60kg/m³, this is a dense, supportive foam — it contours closely to your body shape under pressure and recovers slowly when you move. The 4cm depth adds a noticeable change to how a firm mattress feels without dramatically raising the sleep surface.

The bamboo jacquard cover zips off for washing and is softer and more breathable than a standard polyester cover. The foam core itself is not machine washable — remove the cover before washing.

A fully elasticated skirt keeps the topper in place over the mattress. No straps required.

Using this mattress topper in an allergy-aware bedroom

According to the manufacturer, this topper is hypoallergenic. Research indicates the odds of successful dust mite avoidance are much higher when multiple strategies are combined rather than relying on a single measure alone (Wilson & Platts-Mills, 2018).

Because mattress toppers sit between the mattress and the sheet, they are in close contact with the mattress — one of the densest dust mite habitats in the bedroom. Encasing both the topper and mattress in dust mite covers provides a physical barrier at both layers. For a full guide to building an allergy-aware bedroom, visit our low allergen bedroom hub.

A complete allergy-aware bedroom typically includes:

• Dust mite covers — physical barriers for your topper, mattress, pillow and quilt
• A dehumidifier — keeping humidity below 50% limits dust mite survival
• An air purifier — reduces airborne allergen particles
• A HEPA vacuum — helps reduce allergen from carpets, rugs and upholstery

It's worth noting that 'hypoallergenic' is not a regulated or standardised term in Australia — there is no official threshold a product must meet to carry the label. The manufacturer's claim reflects their own assessment rather than a certified standard.
