HOWDIA 4pcs Office Chair Armrest Covers, Elastic Band Computer Chair Arm Covers Protectors for Desk Chair Rotating Chair ,Length-25-39cm(Black)

I purchased to protect the arms of my Secret Labs chair, as apparently according to Secret Labs customer service warranty department "the rubber on the arm rests is susceptible to deterioration if exposed to sweat".The covers of course are one size fits many (not all). They do cover my arm rests but a precise fit. There edges of the cover are a little short on the sides. But my (acording to Secret Labs) overly sweaty arms only make contact with the top of the arm rest.The covers are of reasonable quality and seem to be doing the job I got them for. They do not make the arm more comfortable but then they were not uncomfortable in the first place, just made of a rubber that is not fit for purpose.

For what they are getting 4 covers is great value. They protect the walls from marks but are a bit too narrow for my chair arms so lower rating

Did not stretch as indicated on listing , very thin fabric indeed.Sent it back and used a couple of socks instead.
