I have a 3 months old ergonomic chair from Ergoworks, RH LOGIC 400 XL (priced at S$1600) for sales. Neck Rest - can be adjusted by height and depth Backrest - generous adjustable lumbar support, providing comfort for entire back Angle of the backrest - can be adjusted seaparately, enhancing individual comfort and support Seat Height and Depth - can be adjusted quickly and simply, controls can be accessed even when seated and are marked with pictograms to make them easy to understand. Correct height improves blood flow to the legs while correct seat angle provides better comfort and support Lumbar Support - provides extra support for the lower back and consequently, for the entire back. The pump adjusts the amount of air in a lumbar cushion, providing extra support. Armrests - are height and width adjustable. Can be rotated, highly recommend armrests as they provide support for the shoulders, giving you comfort for long periods at your desk and ultimately long term health benefits. Base - polished aluminium Castors suitable also for parquet Color - Black Synthetic leather May request for viewing.
