The osit wooden evolving seat comes with the wooden safety bar included. Cushions and bags are not included. The osit wooden evolving seat grows with the children, offering two different seat heights. This means that it can be used with babies from 6 months with the safety bar (adding a safety harness too if you wish) and up to approximately 6 years.

When the child grows, the safety bar can be removed and the osit wooden evolving seat works for a child of 1 to 3 years. The child continues to grow and the osit wooden evolving seat does too. The seat can be turned 180º and becomes a wooden seat for children of 4 to 6 years.

More info

The osit wooden evolving seat is made in Europe with FSC certified beech plywood from sustainable forests, so they are committed to environmental sustainability. The wood is finished in water varnish and whiteboard paint so children can play on all of the white parts with crayons, chalk or board pens.

Easy to clean. Any specific wood product can be used to clean the white parts of the seat, and a damp cloth for the wooden parts.

The osit evolving wooden seat can begin to be used once the child has control over their torso and neck. The osit wooden evolving seat has been designed following the stages of child anthropometry; in it children control their posture and the cervical-dorsal-lumbar alignment, and can support the whole of the spine and part of the head on the back and thus start to independently handle food, books and games.

Medical experts in child posture are analysing the osit wooden evolving seat and for the moment the results have been very favourable.

The child grows along with the osit wooden evolving seat, gains freedom and learns to choose their own activities. The circles on the sides make it easy for children to move the seat, thus turning it into a game for them. 

The osit wooden evolving seat offers many possibilities and has a large variety of complements. These include the tray, allowing us to create a low high chair ideal for playing, eating and other manual activities.

The safety bar can be used to hold the wooden rings from sustainable forests, handmade with natural and non-toxic dyes. A simple and useful complement. The wooden rings can be stacked, grouped, ordered and help children to enjoy learning the colours of the rainbow. 

When the children discover the drawer in the osit wooden evolving seat they love it; tidying and untidying books, toys… It is an ideal place for them to keep their treasures. Everyone keep out!

Did you know you can personalise your osit wooden evolving seat? You just have to choose how:

With one of our vinyls we will send you the name you require.

As you can see, the osit wooden evolving seat is a seat that can start to be used from 6 months and as our child grows, it adapts to their needs. But did you see how the osit wooden evolving seat forms part of the oUeat convertible high chair? By just adding the wooden legs Ustructure you can turn it into a high chair, seat and table or a play place. 

And in the future, by just adding the hchair creative seat and the Itop top you can have these two magnificent wooden units for any children’s room. 


Finally, the osit wooden evolving seat is the first on the market conceived for one child or for twins or children of similar ages. If you are interested, take a look at the furniture for twins.

As you have seen, the nuun kids design children’s furniture offer many possibilities and adapt at all times to our children’s growth. But if you still are not sure, tell us your expectations, needs and likes by writing to and we will send you what we think is most convenient for you.
