MKS Dream Comfort Memory Foam Topper 140 x 200 - 5 cm Gel for Mattresses Ergonomic Mattress H3 with Cooling Effect & Breathable Cover Sleeping Like on Clouds

For firm lying surfaces: hardness H4 – the topper makes a mattress that is too soft or slackened significantly firmer. Not intended for those who prefer a soft, supple lying feeling. Evenly firm foam core: 5 cm PU comfort foam with density 25 kg/m³, dimensionally stable and even. Dimensions: 140 x 200 cm - please measure the size of the mattress before ordering. Vacuum packed and rolled: please spread for 24-48 hours, low temperature up to 72 hours. Then the topper has its full height and the folded edges have disappeared. STAYS IN PLACE - The non-slip fabric backing provides support - ideal for box spring beds, guest beds, sofa beds and regular mattresses, even if you often turn at night. Cover with zip on three sides: top 250 g/m² polyester fabric (100%), on the sides 250 g/m² knitted fabric without mesh. Simply peel off, just air the foam core itself.
