Designed for maximum comfort - the innovative Renya office chair, thanks to the mechanisms used, enables 100% back support. Studies at MDD have revealed that traditional chair models do not provide support for the lumbar spine in an inclined position. To counteract this phenomenon, we have developed a backrest with an adjustable tilt point in the range of 8 cm with a simultaneous additional movement range of +/- 30 degrees. This effect is provided by one setting, which is an advantage over traditional solutions that require multiple adjustments.
