Trundle bed mattresses need to be chosen carefully — the right height for each berth is essential to ensure both sleepers are comfortable and that the lower mattress slides smoothly beneath the upper frame.
At Colchón Exprés, we stock trundle bed mattresses in a range of thicknesses and sizes from trusted brands including Flex, Ingravity, Pardo and Viscozhen — so you can find the right option for both the upper and lower sleeping positions, at a great price.
Our sleep advisors are on hand to help you match the right mattress to your trundle bed model. Free delivery is included across Spain, and flexible payment options are available on all orders.
