This is hands down the best futon mattress I have ever met. The thickness, consistency and comfort made this well worth every penny. I have aired it for 48 hours as recommended and it is at its max. I couldn't be happier. I did order a futon slip cover from a separate retailer and would recommend sizing 1 inch down, i.e., the mattress is 10", but should by a 9" cover. It is memory foam so there is more give and plushness than regular mattresses.
