Grey jumbo cord folding foam seat/mattress (Leighton Buzzard LU7)

Used. Washed. The foam is very squashed but can be replaced (either foam pieces or bean bag crumb) Fine for kids. I'm 5ft3 and slept on it last year (camping). I did think about stuffing it with cheap pillows (or even washed old pillows- I checked, each pad will take 2 pillows)
