The construction of the saddle allows the pelvis to move horizontally. The execution of the so-called pelvic swing is thus guaranteed, as with natural walking. This ensures a round step which can relieve the strain on spinal discs and facet joints. This can contribute to fatigue-free riding and to the prevention of complaints in the area of the lower lumbar spine.

In cooperation with the Sqlab research and development laboratory, the Frankfurt University of Applied Sciences and the Frankfurt University Hospital, the new Ergowave saddle shape was developed through a government-funded research project. The latest findings on the stress limits of skin, muscles and fatty tissue, as well as the nerves and blood vessels located in the perineal area, led to the new Ergowave saddle shape for a sporty riding position. The raised rear with a slightly rounded step and the subsequent wave shape that merges into a second small step gives the pelvis a lot of support, especially towards the back, and the pressure is distributed evenly over the ischial branches down to the deep structures.

MaxContact® Concept
The saddle noses of the SQlab step saddles are, according to the SQlab MaxContact® principle not curved, but flat. This increases the contact surface without increasing the width of the saddle nose. This means more safety and comfort when sitting dynamically.

Saddle Width System
Many SQlab saddles are available in different widths, because " buying a saddle is like buying shoes" - the size has to be right! The most important thing with the saddle is that both seat bones sit completely on the saddle.

SQ-Shore is the unit for the upholstery hardness of the saddle. SQlab saddles are available from 30 - 70 SQ shore. The higher the shore, the harder the saddle.
