I tested the Herman Miller Sayl and Knoll ReGeneration to see which chair feels better for daily desk work. Both chairs have a simple look, but they feel quite different when I sit in them. The Sayl has an open back that gives me a light and airy feel. The ReGeneration has a flexible back that lets me move more as I work. I looked at fit, back feel, seat space, room size, and daily use. I also paid close attention to what each chair does well and where it falls short. In short, the Herman Miller Sayl is my pick for a compact office, while the Knoll ReGeneration may suit people who like more freedom to move.
Herman Miller Sayl Review
The Herman Miller Sayl is a great fit for my smaller home office setup. I like its open back because it does not make me feel boxed in while I work. The back can flex as I lean or shift, which makes normal desk work feel more natural. I found the chair useful for long typing sessions, reading, and video calls. Its small frame also leaves more room around my desk. The seat height gives me a good range for finding the right desk fit. For me, the Sayl feels like a smart mix of simple design, easy movement, and solid daily use.
Pros
- Open back: I liked the airy back because it gives my upper body more room to breathe.
- Compact frame: I found it easy to fit the chair beside a smaller home desk.
- Good weight limit: The 350-pound limit gives this chair a useful edge for many US buyers.
- Flexible feel: I liked how the back moved a bit when I leaned or changed my pose.
- Long warranty: The 12-year warranty gives me more peace of mind for long-term use.
Cons
- High price: I would spend much more on the Sayl than on a basic office chair.
- Firm feel: The seat may not suit me if I want a very soft chair.
- Different back design: The open back can take some time to get used to if I normally use a padded chair.

| Material | Elastomer back, foam seat, fabric cover |

The Sayl has a flexible elastomer back and a padded seat. Its seat height can adjust from about 16 to 20.5 inches. The seat depth can also adjust from about 16 to 18 inches. The chair has five wheels and a weight limit of up to 350 pounds. Its smaller frame is one of the main reasons I would consider it for a home office.
Is the Herman Miller Sayl Good?
Yes, I think the Herman Miller Sayl is good for the right type of user. I like it most when I need a chair for typing, writing, and normal computer work. The open back gives it a much lighter feel than a chair with a large padded back. I also like having a wide range for seat height because it helps me match the chair to my desk. The smaller frame is another plus when floor space is tight. I would still try the chair before buying if possible because the seat and back feel are not the same as a soft padded chair.
My Recommendation
I recommend the Herman Miller Sayl to buyers who want a premium chair that does not take up too much room. I think it works best for a home office, small work area, or desk where space matters. I would look at other chairs if I wanted a very soft seat or a deep sitting area. I also like the Sayl for buyers who want a long warranty and a higher weight limit. For my needs, it is the better choice when compact size and an open sitting feel matter most.
Knoll ReGeneration Review
The Knoll ReGeneration is a good pick for me when I want to move more while I work. Its flexible back lets me lean, turn, and shift without feeling stuck. I like this most when I switch between typing, reading, and looking away from my screen. The seat also gives me enough room to change my sitting spot. Compared with the Sayl, the ReGeneration feels more open when I move from one pose to another. For active desk work, I think this chair has a lot to offer.
Pros
- Flexible back: I liked how the back moved with me instead of holding me in one fixed pose.
- Roomy seat: I had more space to shift my legs and change my sitting position.
- Good for movement: The chair felt natural when I leaned or turned during desk tasks.
- Simple design: I found the controls easy to learn without spending much time on them.
- Light build: The chair feels less heavy than many large office chairs, which I liked when moving it around my work area.
Cons
- Higher cost: The ReGeneration is not a low-cost chair, so I would compare it with other premium chairs first.
- Large width: It needs more room than the Sayl, which may be a problem in a small home office.
- Different back feel: The flexible design may take some time to get used to if I prefer a firm chair back.
