Ultra-thin type with a thickness of 1 cm Soft, thin, and lightweight, so there is little difference in height, and it can be used without any discomfort in combination with beds and circles. Easy to move when in use! Does not take up much space when stored. I used it for my Chihuahua for 3 seasons. I put it under the pet bed, and he was sleeping soundly with a very happy face ( ˊ̱˂˃ˋ̱ ) I have confirmed that it works, and it can still be used. I am selling it because I bought a new blanket this winter.
