New product


This set is ideal for a couple of babies, twins or children of similar ages. The osit wooden evolving seats offer many possibilities and can be used together or separately.

This pack comprises osit wooden evolving seats along with a tray conceived for two children of over 6 months in age to share and interact together. The wooden tray allows the two osit wooden evolving seats to be easily fixed and connected by means of the grooves below in an articulated manner. Cushions and bags are not included.

The osit wooden evolving seats are made in Europe with high quality beech plywood from sustainable forests in the north of Europe. 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. Clean it with just a cloth with a specific product for wood.

The osit wooden evolving seat is recommended from the time the children can hold their heads firm, at around 6 months. Each of the osit wooden evolving seats includes a safety bar. It is recommended to have this safety bar in place up to two years, and after this the seat can be used without the bar up to three years. From here, and depending on the child’s height, the seat can be turned 180º to be used up to 6 years of age. 

The osit wooden evolving seats have a wooden safety bar, but they can be provided with the safety harnesses to make children more protected without depriving them of their movements.

To fit the wooden tray the safety bar has to be in place to hold it. Each wooden tray has two mechanisms to fix it to the seat, so babies cannot move it.

If you wish, connect the two osit wooden evolving seats by simply placing them facing each other and using the tray to fix them. In this case we recommend placing the mechanisms in diagonal (see product pictures). 

Although this pack comes with a single tray, it is a good option to add a complementary tray for each child to have their moments of independence.

In their early months of life, twins are often smaller. It is therefore recommendable to use the baby cushions with removable side reducers so they are firmly supported.

And what happens when the children grow? After two years of age, children want freedom. 

They hate being strapped in. Here we have the nenjoy wooden table, which is a wooden connecting table which joins the two osit wooden evolving seats using no mechanisms, just the side grooves of the osit wooden evolving seats. They can therefore fit and remove it easily. 

The cushions are a basic complement to give our children comfort. The cushions with side reducers have been conceived especially for twins. The side reducers leave them very well protected. These reducers can easily be removed.

The cushions are 100% cotton, reversible and have two possible prints.

It is always good for children to have their own things and to know what is theirs. We therefore give you two options:

To personalise the wooden seats with very amusing vinyl designs! 


Or by painting the white parts of the chair.

As you can see, the osit wooden evolving seat has infinite possibilities. Along with its complements, it is entirely conceived for our children to learn to be creative and to let their imagination run free. If you want, you can put coloured rings on the safety bar for them to play, to learn to colour on the tray that hides the treasures in its secret drawer... Endless things!

If you want your children to be in on the social act at the table, you just add the Ustructure wooden legs to your osit wooden evolving seats. And this will give you a high chair for twins! 

With them you will also get a table, a blackboard, a storage place and even a desk for when the children are older. 

And if you add a couple of hchair creative seats? 

To enhance their creativity, a children’s furniture unit for any baby’s room, a creative space for the children, a small table. . . A marvel. 

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.
