Dual -back chairs worth buying it ? Uh , look at the nature of your work and living conditions , and if it takes a long time to sit every day to work and have some sort of back pain, lower back trouble, the investment is worth it to buy a good chair .

1 Wan RMB for my psychological price is high point, but a thousand or even two thousand I think it is very worthwhile, you have to calculate your entire life , basically in the shoes , the chair , the bed three places of , so I chair , shoes and mattresses should be bought for the job , because the actual long-term use , it is not more than a few hundred dollars to throw away clothes twice more waste.
