White metal playpen which can be converted into a room divider etc. Cheapest I've seen is at kiddicare for £69.95 including postage.
We bought this while I was pregnant with our first daughter - it has been out of the box, assembled, realised we didn't have the room, then put back in the box and stored in the loft. Now with 2 girls we definitely don't have the room although would be handy to protect the little one!
In as new condition, however the mat is probably a little creased as they never seem to go back in the box the same.
