As Mattress topper Dear friends, we need to compress the packaging products, and then ship them. When you open them, the thickness will be about 1-2 cm smaller than the normal size. There will also be some wrinkles. Please put them in the sun for 1-2 days and use them again. Thank you very much for your understanding. If you mind that the product will be compressed, please consider carefully before placing an order.
