This is a BabyBjorn high chair that is currently out of production. The waist belt is difficult to clean when it gets dirty, I chose one without it. It was very useful because the child could not escape even without a safety belt. My child has grown and this chair has become too small, so I am selling it. It was used for about 1 year and a half. There are scratches and dirt, but there are no problems with use, and the table moves smoothly. The removable parts of the table were washed with dishes after each meal. I will wipe it with alcohol, pack it with bubble wrap, and ship it. Regarding specifications and instruction manuals, It is posted on the net. The original instruction manual has been lost, so it is not included. Questions about the purchase date and number of uses We cannot answer. As this is a used item, please understand before purchasing. Please purchase.
