Over-cot bassinet, that will fit any 'large cot', ie: 690mm long and 760mm wide mattress cots (Boori Classic, Ikea, Eco Tasman, etc.) but please measure your cot first.
We used it for only 5 weeks (baby used a First Years Co-Sleeper, then we used the Papoose to transition her into her own room but she outgrew it too quickly). I strongly recommend renting bassinets on a weekly basis, rather than buying them as you just don't know how fast your baby will grow!
Comes with mattress, base board, mattress protector, white cotton fitted sheet if required.
