My cousin sister commented how nice and comfy my computer chair is. She works at a desk from nine to five for years but lately her back and shoulders hurts. Most probably her chair is inadequate in terms of support. It is important to make sure office furnitures, especially chairs and desks are ergonomically designed for people to sit and work for very long hours. I told her how I’ve suffered for years sitting on cheap badly designed chairs. Although my chair now costs twice as much as any previous ones, it is worth the money.
