Super king mattress

In perfect condition, spotless, no smells. Used for a year, comes from a pet-free and child-free household of one female. Selling because I move out in the end of summer. Collection only, I don't do delivery. Location Newmarket, co. Cork. I included a photo of my staircase for a buyer's knowledge, it might be difficult to squeeze the mattress through the door frames and the staircase. But I think it is manageable. The mattress height is around 2.10m, the staircase and the lowest point is around 1.65m. Also it is better to carry the mattress with two-three people as it is heavy. Original price was €650. My price is negotiable.
