The first ergonomic chair your
back and wallet both love.

Auxilium Chair

Before Lightn, chairs weren't great.

No back support.

Normal chairs don't offer back support - they look comfy without actually being comfy.


Chairs actually designed to make you healthier cost an arm and a leg. A desk chair shouldn't cost more than a couch.

Returns were awful.

Expensive shipping and returns made trying out a new brands chair really risky.

Lightn Auxilium Chair


What our early customers are saying.


This chair feels amazing, the cushion is so comfortable. I was very surprised with the arm rests, they are so supportive and I like to rest my arms on them while I'm typing. The lumbar support is great, it supports my back so that when I'm sitting I have better posture and less muscle cramps later. I was a little skeptical about trying the new design from Lightn but everything is great thus far!

This is a simple office desk chair with breathable mesh on the back, and 3D mesh on the seat and lumbar support. The lumbar support is modest but definitely there. The head rest is a really nice feature.

David S.

A wonderfully comfortable chair, that assembled quickly and easily.

Robin B

I sit in a chair for a bit portion of my day so having a good one is incredible important to me. After having assembled this chair, it clearly is a great one. Assembly was easy and instructions were clear, all the bolts were packaged in a very organized way which I really appreciated. The chair itself is so comfortable.

We have been redecorating my daughters room, sold a bed and got a lot of space so this has been perfect!

Main advantage of this chair is the cool design: I like the colors, the blue and grey are great. It took us about 20 minutes to assemble but thats because we had a little “helper” with us :)

Samantha S

I love the price point. I know many more of us are working from. home offices, as am I. This is a far superior desk chair than the folding beach plastic webbed contraption I had been using in my office.

What makes the Auxilium chair unique?

Using the T-Bar is simple.

Sit Straight

Adjust the T-Bar Vertically

The Bar should be sitting slightly above your hips for a proper fit.

Feel the Support

Work harder at your desk and feel more energetic when you leave it.

A seat so comfy, you forget you're sitting.

Chair is solid. Super comfy and it looks great. I wish the arm rests were an inch lower though.

Brad H

I love how the chair looks and feels! 

Stephanie L

I really love the chair, as I do a lot of Zoom stuff and it is nice to lean back into the headrest. The lumbar support is really nice.

Bruce B

I love the price point and this new brand! I know many more of us are working from. home offices, as am I. This is a far superior desk chair than the folding beach plastic webbed contraption I had been using in my office.
