Sage is all about quiet luxury. It's the kind of green that invites calm and adds an understated touch of nature to the room. Perfect for those who want a peaceful, cool-toned escape, without the drama. Our Small Waterproof Bassinet Sheets are the smallest size, they are a great option for bassinets with small & very thin mattresses like the Snoo, pram bassinets. Please check out our sizing tool if you need help to pick the right size. Got a co-sleeper? You'll need our next size up.
