I purchased this new in July of this year and used it for about half a month. Then, my care manager recommended a rental from France Bed, so I switched to that and no longer use this one. I highly recommend it to anyone who would like to try it. Since it has been used so little, it is clean and in beautiful condition. 【Silent Air Pump】The low noise (≤45 decibels) of the air pump when it is operating will not affect the patient's rest. The operating power can be adjusted freely, so you can change the softness of the air cushion by adjusting the air pump. There is a hook on the back of the air pump, so you can hang it on a table or bed. 【Air Cushion Material】The air cushion is made using fully automatic integrated high-temperature hot-press technology, making it durable, well-sealed, and leak-proof. It uses high-quality, soft PVC fabric, which fits better, is gentle on the skin, and is harmless to the body. It is odorless, breathable, non-sticky, does not cause sweating, and keeps the skin dry. Please avoid puncturing the surface with sharp objects during use.
