Orthopaedica Range – Optional Features explained:
Seat Slide:
An adjustable seat slide moves forwards and backwards, making it easy to find the right fit for different thigh lengths. By adjusting the seat depth to suit your body, you can enjoy better thigh support while sitting comfortably against the backrest, helping you maintain a more natural and supported sitting position throughout the working day.
Inflatable Lumbar:
The inflatable lumbar support lets you tailor the level of support to suit your body and seating preferences. By filling the natural gap in the lower back, it helps maintain the spine’s natural inward curve and encourages a more comfortable sitting posture. Ideal for long working days, it provides targeted support where you need it most.
Coccyx Cut-out:
Designed with comfort in mind, the optional coccyx cut-out features a specially shaped area in the seat to reduce pressure around the tailbone. This thoughtful design helps relieve pressure at the base of the spine, making it a useful option for those who need extra comfort and support when seated for extended periods.
Muti-functional Arm Pad:
Find your ideal seating position with adjustable arm pads designed to suit your body and working style. The width adjustment lets you position the arms for a more comfortable fit, while the depth adjustment makes it easy to sit closer to your desk or move back when reclining. Whether you’re focused on detailed tasks or settling in for a long working day, enjoy arm support that adapts to you.
Adjustable Thoracic Support:
Enjoy support where you need it most with the optional inflatable thoracic support. Easily adjusted to suit your preferences, it fills the natural gap around the upper back to help support the spine’s natural curve and encourage a more comfortable sitting posture. Ideal for those who spend long hours at a desk, it offers a more personalised seating experience while helping reduce strain across the upper back.
