The published seat-height range is 400–520 mm ('between 40 and 52 cm' (DIN 4550 gas lift); brochure drawings 40/52 cm). It spans the full EN 1335-1:2020 range for Type A, Type B, Type C.

Seat-height range compared with EN 1335-1:2020 types EN 1335 Type Ax: 400–540 mm; EN 1335 Type A: 400–520 mm; EN 1335 Type B: 420–510 mm; EN 1335 Type C: 430–480 mm; ON (174/7): 400–520 mm 380420460500540580620660 EN 1335 Type Ax EN 1335 Type A EN 1335 Type B EN 1335 Type C ON (174/7) 400–520
Seat height in mm, loaded seat. Grey bars: the range each EN 1335-1:2020 Type must cover. Black bars: the manufacturer’s published range.

Using the popliteal-height ratio of 0.255 × stature and a 25 mm shoe allowance (Pheasant and Haslegrave, Bodyspace; see the height calculator), this range puts the thighs roughly level for people about 147–194 cm tall. That is an estimate from average body proportions, not a fitting.
