Casper might be the best mattress for everyone, but not for your houseguests. Put them on this discounted Insta-Bed, marked down to $90 on Amazon today.
That’s more than a lot of air mattresses, but this one includes a built-in pump with silently trickles more air into the mattress overnight, meaning it’ll still be fully inflated when they wake up in the morning. I got one of these a few months ago, and it’s as good as advertised.
