The orthopedic futon can be used alone, but if you are concerned about it, please place a moisture absorbing pad under the orthopedic futon. The size (single size) is perfect for the size of the orthopedic futon.
If you place it under a mattress that tends to accumulate moisture, it will effectively absorb moisture while sleeping and support a comfortable environment. The outside is made of 100% cotton material that easily absorbs moisture, and the lining is made of a honeycomb net with a three-dimensional polyester mesh structure.
