chair is awesome!!
The product was fine and i am well satisfied. Thanks for the amazing work.
I am totally satisfied. Had a frequent neck issue. Now its kind of cured. Didnt get one for a long time
It is an amazing chair and one of the best investments.
Look for the R and L marking under the seat near the Retractable Footrest holes and install the R and L Hand Rests accordingly (hand rests have R,L marking on them but the base has nothing to go after and instructions won’t indicate either).
Installation won’t be difficult unless you grew up without playing building blocks/lego.
Just got this ergonomic chair from Rae with a leg rest, and I’m really happy with it so far. It’s super comfortable, and the leg rest makes a big difference when I want to relax. The back support feels great, and it was pretty easy to assemble. Excited to see how it holds up over time!
