Transform your sleep surface with the 4AS Global 10cm Extra Thick Mattress Topper. At 1100GSM with a deep box-stitch construction, this topper delivers the plush, cushioned feel of a luxury hotel bed without replacing your mattress. The microfibre fill retains its loft wash after wash, making it one of the most durable comfort toppers available at this price point.

Who It Is For

This topper is ideal for anyone sleeping on a mattress that is too firm, has developed uneven wear, or simply needs a comfort upgrade. The 10cm depth provides maximum cushioning and is particularly well suited to those who experience hip, shoulder or lower back discomfort during the night.
