The design and selection of educational furniture play a crucial role in creating effective learning environments. One of the key standards that governs the dimensions and ergonomics of classroom furniture is the British Standard EN 1729. This standard provides guidelines for the sizing of tables and chairs used in educational settings, ensuring that they are appropriate for the age and physical stature of students.

Each size mark corresponds to a specific seat height and approximate child height range. The size mark on the chairs is then paired with the size mark on the tables to ensure they are the right size for each year group.

Size mark 3 chairs pair with size mark 3 tables
Size mark 4 chairs pair with size mark 4 tables 
Size mark 5 chairs pair with size mark 5 tables
Size mark 6 chairs pair with size mark 6 tables

Note: Both size mark 4 and 5 can be used for year 6. We would recommend size mark 6 for those with taller children
