Raj Gupta 5 The mattress is easy to inflate and the air stays in. I tried it at home. Inflated at 5PM then slept whole night on it. Even at 9 am tomorrow the firmness was same.Separate to it - I interacted with the seller and all I can say is the experience was only pleasent. I rate the seller 5 star too. If any issues I suggest just reaching out to seller.
