It depends on the item, but yes there are weight limits for particular nursery furniture items. Bassinets, like the Tasman Eco collection, have a weight limit of 9kgs, we recommend that a baby sleep in their bassinet up until 4-6 months, pending how your baby is growing and moving. For a baby cot, if using the bassinet height, this will be used from birth up until 4-6 months. Then, once shifting to the cot height your baby could be in their cot up until they are around 3 years old, pending their growth milestones and the move to a toddler bed or single bed. The weight limit on Tasman Eco cots is up to 50kgs.The weight limit on Tasman Eco compact cots is around 30kgs.
