After one charge, the anti-bedsore mattress will be a little loose and the size will be different from the standard. this is normal phenomenon. The material of the airbed is somewhat elastic, and it feels very relaxed after inflation. Just inflate for a while to get the desired effect, but don't inflate too much.

Make sure there are no sharp objects such as nails, thorns, etc. on the floor or bed frame of the anti-bedsore mattress.

When the temperature rises in the season, the gas in the bed expands, pay attention to deflation.

Don't over-inflate at any time, especially in summer, or the anti-bedsore mattress straps will overload and break, causing the bed to bulge beyond repair.

The anti-bedsore mattress softens when the temperature drops. Pay attention to supplemental air. It is normal for any inflatable product, including tires, to leak naturally. Pay attention to the timing of gas supply.
