This extra thick 4 inch topper uses a dual-layer construction to deliver instant pressure relief and balanced support, helping improve comfort without replacing your mattress. Its 2 inch cooling gel memory foam layer helps reduce heat build-up, while the 2 inch bamboo charcoal memory foam supports freshness and helps reduce odours. For a secure fit, the non-slip base is paired with adjustable elastic corner straps to keep the topper in place.
