Benefits of Upgrading to a Memory Foam Mattress
-
Customized Contour Support: Viscoelastic foam responds dynamically to body weight and heat, molding precisely around joints to eliminate shoulder and hip pressure.
-
Silent Sleep System: Free from internal wire springs, memory foam mattresses operate completely silently without squeaks or partner disturbance.
-
Hygienic & Hypoallergenic: High-density foam structure resists dust mites, bed bugs, and allergen buildup, promoting a cleaner sleep environment.
-
Versatile Placement: Suitable for use on flat upholstered timber bases, solid slat frames, or platform bed bases.
Range Options: Finding Your Ideal Mattress
Whether you need a high-density orthopaedic option for back support or a cooling gel layer for warmer nights, we offer a range of memory foam mattress builds:
-
High-Density Memory Layering: Rest on a firm supportive core topped with responsive memory foam for balanced cushion and support.
-
Cooling Gel Memory Foam: Advanced gel beads within the foam draw excess heat away from the body for cooler night-long comfort.
-
Removable & Hypoallergenic Covers: Finished in breathable, soft-touch fabric covers that enhance air circulation.

Frequently Asked Questions
Can I put a memory foam mattress on a slatted bed frame?
Yes, provided the slats are sturdy and spaced no more than 7 cm apart to prevent the foam from sagging between gaps.
How do I maintain my memory foam mattress?
Use a quality waterproof mattress protector to guard against moisture and dust. Rotate the mattress 180 degrees every few months to maintain smooth surface uniformity.
How long does a memory foam mattress take to adjust to my body?
It typically takes 10 to 14 nights for your body to acclimate to the corrective posture support of a new memory foam mattress.
