Your spine, back in alignment
A mattress with uniform support either lets your lower back sag or pushes it up too firmly. Ru9 Contour 3-Zone tunes firmness separately for Shoulders – Back – Legs, relieving pressure points. Your spine keeps its natural posture throughout 6–8 hours of sleep.
Cool all night long
Regular memory foam builds up heat after 1–2 hours. Graphene in the topper draws heat away from contact points and disperses it across the entire foam layer, while the Tencel fitted sheet wicks moisture faster than cotton. A cool surface, with foam that keeps consistent firmness — no soft spots.
Keep your topper under warranty
For a topper mattress like the Original Pro, liquid stains larger than 30cm may void the warranty. The Mattress Protector’s TPU backing blocks 100% of liquids before they reach the foam. Your topper stays clean longer, extending the time before it needs replacing.
