Design history & editions
Sources consulted 3 September 2026. This date applies to these notes, not a fresh verification of every inherited specification.
Bring the chair to the shared table
Opsvik's 1972 design addressed the mismatch between a child's size and an adult dining table. His account explains the aim as one chair adaptable to different-sized people, bringing children into the same activity rather than seating them at a separate low table. [1]
An adjustable seat and an adjustable floor
The backrest stays at table height while both seat and footrest adjust in height and depth. Opsvik describes the broad footrest as a floor that supports movement and changes of posture. The mechanism is therefore about the relationship between feet, seat and table, not simply lifting the seat higher. [1]
Stokke describes the chair as made primarily in European beech and oak. A wood species belongs to a selected configuration; the family name does not identify the timber of an individual chair. [2]
Accessories have their own history
Opsvik's account distinguishes the early wooden support rail from the later Baby Set. It dates the Newborn attachment to 2010 and an angle-adjustable revision to 2019. The basic chair's long life does not mean that every accessory belongs to the same generation. [1]
Models and editions
| Model / edition | What distinguishes it |
|---|---|
| Chair | The adjustable wooden chair is the reference object; accessories are separate configurations, not included automatically in its dimensions. [3] |
| Baby Set / Newborn Set | Stokke presents these as distinct additions for different stages. Their product names are not interchangeable and their current instructions must be consulted separately. [3] |
What this record does not establish
This is a design record, not a child-safety or compatibility guide. Do not infer that an older chair accepts a current accessory. Use Stokke's current instructions for the exact chair, accessory generation and market; this entry deliberately makes no age, weight or fitting recommendation.
