Futon company double futon mattress (Spinningfields M3)

This is a futon company futon mattress that came with a sofabed base which I have sold. 135x195 cm. It's in good condition except for a couple of coffee stains. It smells a bit of tatami mat because it has been resting on a tatami base for a while but I have washed the cover in the last 6 months and you could do the same, it's a bit of an art reassembling the contents but very achievable.
