The range of ESTRO stools for dentists is the result of careful research aimed at obtaining balanced posture and avoiding particular pressure in the support and contact areas. Three models are available: ESTRO SL, a saddle stool without backrest, ESTRO L with a wrap-around backrest, ESTRO PL with an anatomic backrest. All three models have a five-spoke aluminium base, also available with a footrest ring, gas shock absorber with 18 cm stroke, silent and self-braking castors.
