TL;DR: These are two very different chairs for two different buyers. The Titan Evo is the better chair if you want a wide seat, a tall back, a gaming aesthetic and the highest weight rating in this comparison. The Series 1 is the better chair if you want genuine adjustability, a twelve-year warranty and a mechanism that will still feel right in a decade. For most people who sit at a desk for work, the Series 1 is the better choice.

Steelcase Series 1 — the better desk chair
Series 1 wins on the two things that decide long-term comfort: adjustability and warranty. The seat depth range means the same chair fits a short-thighed and a long-thighed person. The lumbar support adjusts in height. And the twelve-year warranty is a real claim about durability that a five-year warranty is not.
For anyone who works at a desk, that is the chair to buy. It will still feel correct in eight years. The Titan Evo will not, because its seat is fixed and its foam will have softened by then.
Real downsides: The back lacks the LiveBack flex of the more expensive Leap, so it feels more rigid. The armrests are 4-way rather than true 4D, the seat cushion is firm for the first week, and the seat is narrower than the Titan Evo, which matters if you are broad in the hips.
Secretlab Titan Evo XL — the better wide-seat chair
The Titan Evo XL is the chair to buy if you are tall, broad, or both. The published seat width is around 22 inches, the back is tall, and the 395 lb rating is essentially tied with the Series 1. For anyone who has never found a desk chair wide enough, this is the one that changes that.
The L-ADAPT lumbar is integrated rather than adjustable in height, but it is a genuinely shaped curve rather than a fixed bump, and most owners find it lands in roughly the right place.
Real downsides: The seat depth is fixed at roughly 17 inches, so anyone under about 5’6″ will find the front edge pressing behind the knees. The integrated lumbar cannot be removed. The side bolsters make the usable seat narrower than the published figure, and the seat edges are firmer than the centre, which creates pressure points on longer sits.
Head-to-head by use case
| If this is you | Buy this | Why |
|---|---|---|
| Full-time desk work | Series 1 | Adjustable seat depth, 12 yr warranty |
| Tall (above 6’2″) | Titan Evo XL | Tall back, high weight rating |
| Broad hips or wide seat needed | Titan Evo XL | Widest published seat width |
| Short (under 5’6″) | Series 1 | Seat depth adjusts down |
| Want the longest warranty | Series 1 | 12 yr vs 5 yr |
| Gaming or streaming setup | Titan Evo XL | Aesthetic, recline, accessory ecosystem |
Which one lasts longer?
The Series 1, and the gap is larger than the price difference suggests. A twelve-year warranty against a five-year warranty means Steelcase expects the mechanism, foam and frame to survive roughly twice as long. Secretlab sells a premium-feeling chair with a mid-range lifespan.
If you buy the Titan Evo XL and keep it for eight years, you will likely have replaced the gas lift once and the armrest pads once, and the seat foam will have flattened. If you buy the Series 1 and keep it for eight years, you will likely have replaced nothing and the seat will still be firm.

Frequently Asked Questions
Is the Secretlab Titan Evo worth the money?
For a tall or broad person, yes — it is one of the widest seats available at its price. For an average-sized person who works at a desk, the Steelcase Series 1 gives you more adjustability and double the warranty for similar money.
Is the Steelcase Series 1 a gaming chair?
No, it is an office chair, and it looks like one. If you want the reclining and aesthetic of a gaming chair, the Titan Evo is the better fit. If you want something that will still be comfortable in ten years, the Series 1.
Which is better for back pain?
The Series 1, because the lumbar support adjusts in height. A fixed lumbar curve, however well shaped, is in the wrong place for a meaningful minority of buyers.
How do I choose the right Secretlab size?
Size S for under 5’7″ and under 220 lb, size R for most adults, size XL for above 6’0″ or above 240 lb. The XL is the one to buy if you are tall — the S and R have shorter backs.
Do either of these chairs work for short people?
The Series 1, yes. Its seat depth adjusts down to 15.3 inches. The Titan Evo’s fixed 17-inch seat is too deep for anyone under about 5’6″.
