If you’ve ever offered to have someone stay the night after a boozy session at the pub, or you’ve had some unexpected plus-ones arriving for Christmas, having a quick-inflating air bed is an absolute godsend. The Airefina King Inflatable Air Mattress is currently a steal on Amazon, available for just £69.99, slashed from its original price of £109.99 (price correct at time of writing).

This king-sized air bed is a dream come true for those surprise overnight stays or extra Christmas guests, inflating in about three minutes with a built-in pump you won't misplace. It’s robust too, sporting 40 internal coils and a high-strength framework that can support up to 317kg. Lightweight at only 8.2kg when deflated, the mattress folds compactly to 44x23x34cm, perfect for camping if you have a spacious tent, reports the Daily Record.

Its anti-slip base promises stability on slick surfaces. And according to enthusiastic Amazon purchasers, it lives up to the hype, boasting a commendable 4.2 out of 5 stars from 3,572 ratings.

One satisfied buyer shared: "I bought these for Christmas when all the family will be here," adding, "My grandchildren will use them. They tested them by staying over and said they were just as comfy as their own beds. Inflating and deflating is as easy as pie. I consider them good value for money. Very very pleased."

"This might be the best purchase I've ever made on Amazon," enthused one delighted customer in a five-star review. "The quality-price ratio is excellent, we use it fairly regularly for guests and it's quick and easy to inflate, deflate and store. It is so comfortable that I've found myself wishing I'd given up my own bed for my guests! " Another chimed in with praise: "Love the air bed, use it regularly for weekends away visiting family and whilst waiting for my bed to be delivered when redecorating bedrooms. It's a good size, elevated off the floor which is my preference as I find lower beds are cold."

However, not all feedback was glowing. "The bed is almost perfect if it had an alternative way to inflate it would be perfect, I'm unfortunately returning as I can't guarantee when we go camping that we will have electric hook up," remarked a less satisfied buyer.

Echoing this sentiment, another added: "If it's recommended for camping then I should be [able] to pump it up without electricity so it's not suitable for camping."

If you’re keen to see alternatives, or you just need a smaller one at a great discount, this Alivio air bed at Debenhams starts from just £36.99 for the single. There’s also this one at Dunelm for £20, although it isn’t self-inflating.

At just £69.99, the heavy-duty Airefina Inflatable Air Mattress Is a great pick.
