Single roll-up futon (New Elgin IV30)

Condition: In good (like new?) condition. Plum colour. I'm assuming it's flame retardant as it's purchased in the UK, but cannot see a label (may be on the inside).

Bought 4 yrs ago during a house move (when awaiting a bed shipment). Used for 3 or 4 nights and then it stayed in my cupboard.

Should be in like new condition as only used a few times and with a matress protector and flatsheet on.

However, rolled up futons may collect dust and it's therefore worth airing it out and giving it some sunshine just in case.
Can be unzipped to wash outside.

Please see photos for measurements.
