Aldi mattress

Has anyone purchased the Aldi mattress-in-a-box in the past? Is it the first time they’re on sale?

We have an old friend staying with us for 10 days next month. Just wandering if they’re ok for temporary use? We don’t have a need for a spare bed, but seems like the cheapest option as we don’t want a used one. Would love to hear thoughts and opinions on it!
