I bought this mattress with the Jorstad bed frame. Very firm mattress but not overly firm to feel like a plank. I read the reviews and bought a full size first, liked it so much and bought a twin for the other room. Comes in a vertical box like a rolled burrito, just take it upstairs and unseal it near the bed. Don't put anything on it for a day and let it fully blow up to its full shape. Foam mattresses are also a fraction of the weight as spring mattress for the same quality. It's such a great invention!
