Ordered design B. Item is light weight and looks durable. Been using fore more than 2 weeks. Felt that it's still a liitle too low for me and I can still cross my legs after putting both feet on the foot rest despite setting at the highest height. The base of the footrest gets in the way of my chair as in I when I try to pull my chair nearer towards the table, the roller on my chair always hit onto the foot rest. Guess design A may not have this problem cos the base is hollow below.

Received in 4 days. Quite bulky. Hard plastic material. Yet to use.
