Mattress came packed in a roll. Easy to open, and unroll. We use it as a loft bed mattress for a 90 lb teenager because it's thinner and keeps him from being too high. I've noticed a little bit of pilling already when I change the sheets which is the only reason I gave it 4 stars instead of 5. I would recommend it as a budget friendly, comfortable option- especially for loft/bunk beds.
