Room Numbers Watch
A large founders room usually contains a washbasin, alongside a wardrobe with draws, single bed with mattress protector and bedding, desk and desk chair and shelving. You also have a large cork board to decorate!
Room layouts can differ on which large room you will have, but when I stayed in founders I had plenty of room for my beanbag that I had brought with me from home.
I've attached a picture of a smaller founders room but it will hopefully give you an idea of what your larger room will have in terms of furniture.
Hope this helps,
