Overall Opinion On This DeviceThis is a very simple way of fixing an office chair Singapore that won’t stay up. Once in position the durable plastic rings should last for many years. The only real downside is if you share the office chair Singapore with others whose working height isn't the same as yours. Also, if your chair has an extended gas lift with more than 4.5 inches of height adjustment you might need two kits.The ideal solution is to replace the gas strut, however old struts can be very difficult to shift when they been in use for any length of time. All in all the Chair Saver Kit makes a neat and easy fix for office chair Singapore that won’t stay up.
