Question 1

Have you successfully swapped out the casters for Roller Blade casters? One review seems to indicate yes, but mfg. says that casters are not standard.

Accepted Answer

Yes!  I purchased the following on Amazon:
“STEALTHO Replacement Office Chair Caster Wheels Set of 5 - Protect Your Floor - Quick & Quiet Rolling Over The Cables - No More Chair Mat Needed - with Brakes - Blue Polyurethane - Standard Stem 7/16.”

(Note): The Stealtho wheels are available with or without brakes.
I am glad opted & I paid extra for the brakes. 
(Brakes are on 2 wheels.)
The Stealtho wheels are blue.  
I like that they won’t turn yellow over time like clear wheels.
Additionally, the wheels are supposed to glow in the dark if you are interested in that sort of thing.
I love the wheels.  I debated about the Stealtho blue wheel on the dark gray T80 Chair.
They looks fabulous.  Glides like a dream.
I love this chair.  I left a review and I posted 3 photos which will show the Stealtho wheels installed.

Question 2

Does the t80 have a forward tilt lever like the t50?

Accepted Answer

Yes, T80 has all the adjustable functions T50 has, but in a more comfortable way. For the details, please refer to the USER GUIDE you can get from the bottom of the product page.

T80 chair in black is on the way to Amazon Fulfillment Center, but due to COVID-19, there is heavy congestion right in front of the center and it has been delayed. Please check again next week.
