bought an double air bed 2 years ago went camping at the weekend its started to deflate not all the way just halfway any tips on how to find if its punctured
Surely if there was a leak it would deflate all the way down and not stop half way. Try the valve, there may be a speck of dust but in any case that would be my starting point in looking for a leak. I've had an Intex Queen for 4 or 5 years now and when this happened on my new one I just blew it up and it hasn't gone down since.
If its a Coleman one it may still be under guarantee. Thankfully Id kept the receipt for mine & managed to get it swapped as its a 2 year guarantee. Ive hung on to my new receipt because I dont think the new one will last too long either lol.
