Bought this for back packing. I carried a small and lightweight bicycle pump to inflate the mattress. I used duct tape to seal the inflator valve to the pump.
Once inflated the pad was soft and comfortable. I tend to sleep more on my side so I did roll off the mummy style pad a few times. I'm thinking I should have bought the rectangular model.
