Invoicing includes additional tax points, please consult customer service for details This product cannot be returned once opened and inflated This product is filled with sponge, and the inflation principle is that the sponge compresses and expands when it encounters air. If you want a fuller effect, you can blow air into it. Moreover, this product is only 2.5cm thick, not very thick at all. Don't expect too much inflation effect. For first-time use, you can shake the sponge and blow air back and forth.Please be cautious when purchasing Thickness issues with our inflatable mattress products: The thickness marked as 2.5cm or 5cm refers to the raw material sponge thickness before production. After being manufactured into a finished product, there will be slight compression. The actual measured thickness after inflation is around 1.5-2cm/4-4.5cm, and there may be errors due to insufficient inflation or other factors. Please be cautious when purchasing, as this is not considered an after-sales quality issue. Please consider carefully before placing an order
