I bought this Twin size Air Mattress for when the Grandkids come over to stay the night. Well, they crawled out of the Air Mattress, and joined me in my Queen size bed in the middle of the night, so I crawled into the Intex Air Bed to sleep. Well, my Granddaughter crawled in later, so I shared it with her. I’m 6’ tall, and she’s a little 7 yo, and we had no problem sleeping on it. My 5 yo Grandson didn’t wake up, and stayed in my Queen size bed. So, it filled up with air really fast, and was very comfortable!   Recommended!
