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!

Lynne B.

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.
