Inflated the product but was disappointed to find the bed deflated over the night. It has only been used by my friend who was of medium built (58 kg/127lbs) for a stayover. Went through the user manual again and made sure that all valves are closed and locked in. Pretty sure it's not a user fault after discussing through with everyone. Following day after, the bed came deflated again and we have to pump air in. Quite disappointed for a product coming from Coleman. We tried several of their products and were quite satisfied with them, which explains us choosing this bed over their competitors.
