Newborn Bear This is a set of Combi Mini bedding, including a mattress, a comforter, a comforter cover, a waterproof sheet, a mattress pad, and a sheet. The sheet has some stains, so if you are concerned, we recommend using a new one. The other items do not have any major stains. A winter mattress pad is also included, as it was available. If you'd like it, we'll include it.
