I was very disappointed, it was  extremely soft and saggy, you could feel all the springs protruding  through the top when you slept on it and everytime you moved you could hear the springs, I thought it might just need longer to fully expandinflate but it was the same after 24hr . I  only used it for one night and had a back ache the next day. Very grateful they have a good returns policy and they accepted it back and sent couriers to collect it.
