Zinus Mattress - Great Condition

Zinus brand mattress, 8-inch Twin, 1.90m high by 90cm wide, I used it for 4 months, always with a cover, until I bought another mattress, and I kept this one saved in case I had visitors, but now that I bought a sofa bed, I think I won't need to keep this mattress any longer, it's almost new, clean and wanting to leave now!
