Very honest mattress for the money with a downside that the accompanying pump doesn't do a great job. Of course, the mattress lost minimal air within 24 hours with two people, which makes it an excellent choice, as all mattresses lose air. I will choose it again.

After 5 minutes of testing with its own pump, I put it aside and inflated the mattress with a blower (you can find it as a "dust blower") for 15-20€. It inflated in 30 seconds.
