The Cocoonababy from Red Castle is an ergonomic, uterine-shaped baby mattress designed with a soft, supportive cummerbund and a 20-degree semi-fetal slope. Retail price 160-170 euros. We used it for our baby boy until around three months, when he started to roll over. It’s very handy when you need to keep your baby next to you in a room without a cot or bed (such as the living room) while they nap. No original packaging – comes in a large Amazon zipped bag. We can also deliver the nest to your door if you live around D1-D4, D6-D8. Included in the listing: - Cocoonababy Nest – Good condition, slight wear and tear (see photos #6 and #7) - Waterproof sheet – Good condition, slight pilling after washing (see photo #5) - Red Castle Dreamy Cloud fitted sheet – Good condition, slight fading and pilling after washing (see photos #2-#4) - Dreamy Cloud tummy band – Good condition, slight pilling and fading after washing (see photos #2-#4) - Adjustable wedge (see photo #5) Recommended use: For babies from 2.8 kg (6.2 lbs) until they start trying to roll over or change position in the nest (typically around 3–4 months old).
