Cybex Eagle selectorized strength line is the evolution of superior technology combined with a passion for fitness. There is no comparable strength line in the industry - Eagle is beyond the other's best. Starting with exhaustive research in human biomechanics and applying the Cybex heritage in sports medicine, Eagle is the ultimate way to "faster fitness results". All strength training is the application of stress. Cybex designs products to apply the appropriate amount of stress to produce the desired training effect but does it in a way that reduces the chance of injury.

Such is the case with the acclaimed Cybex Range Limiting Device (RLD). The innovative designs on the Seated Leg Curl make positioning the tibia pad an intuitive, virtually effortless, one button adjustment resulting in easily accessible and easily adjustable machines. Offset input arm allows for the lower leg pad to adjust with minimal effect on the starting angle of the knee. In combination with proper pivot location, this allows the use of a contoured pad for improved comfort.

The angled back pad (100 degree angle between seat and back) is wider than most leg curl machines and is designed to relieve hamstring tension. The Eagle four-bar linkage combined with gas spring assist means the seat back position can be adjusted without requiring the user to get off the machine. Position indicators enable users to perfectly duplicate their position on the machine each time they use it. The thigh stabilization method used on Cybex Eagle provides significantly reduced shear at the knee compared to other methods.

The versatility of this technology helps the everyday user or the serious trainer achieve greater results by delivering consistent torque throughout the range of motion to maximize the effect at the muscle, with less stress to the joint.
  • Ergonomic Leg Pad Adjustments: These innovative designs on the Leg Extension and Seated Leg Curl make positioning the input pad intuitive and virtually effortless. This results in easily accessible machines that are adjusted with little exertion or movement.
  • Range Limiting Device: This CYBEX patent-pending technology ensures that regardless of starting position selected, the cam is synchronized with each individual user. It matches their performance level, maintaining the integrity of force throughout the range of motion while taking into account their limits and abilities. Start RLD (adjustable start only) provides start positions every 10 ̊ . Total RLD (adjustable start and finish) provides start and end positions every 10 ̊ .
  • Contoured Molded Pads: Ergonomically contoured molded pads provide better support for a variety of movements, as well as a more contemporary overall look.
  • Fully Enclosed Weight Stacks: Enclosed weight stacks help shield bystanders and users from inadvertent contact with the moving weight stack, creating a safer workout environment. The fully enclosed stacks give a sleek appearance and comply with ASTM and EN standards.
  • Drive System Design: A “Best Use” drive design incorporates three methods of transferring force to provide a direct feel and optimal performance. Belt, cable and drive shafts are chosen for their capabilities in specific applications.
  • Gas Assist Adjustments: Eagle’s four-bar linkage design combined with gas spring assist makes it possible to adjust the seat height and back position without requiring the user to get off the machine. The seat base and seat backs have position indicators to enable the user to perfectly duplicate their position on the machine each time they use it.
  • Second Generation Twist Select Increment Weight System: Patent-pending system allows user to adjust the weight 5 pounds (2.5 kg) at a time with a simple turn of the knob—nothing to slide, drop or lose. System is also completely balanced for drag free operation and includes integrated oiling capabilities, resulting in reduced time and mess associated with guide rod maintenance

Leg Extension:

Innovative designs on the Leg Extension make positioning the tibia pad intuitive, virtually effortless, and results in easily accessible and easily adjustable machines. No knobs to lock - just put legs behind the pad and push. Tibia Pad - Offset input arm allows for the tibia pad to adjust without affecting the starting angle of the knee. In combination with proper pivot location, this allows the use of a flat pad for reduced shin pressure. Back Pad Angle - The 100 degree angle between seat and back pad is wider than most leg extension machines and is designed to relieve hamstring tension. Four-bar linkage seat back adjustment with gas spring assist - The Eagle four-bar linkage combined with gas spring assist means the seat back position can be adjusted without requiring the user to get off the machine. Position indicators enable users to perfectly duplicate their position on the machine each time they use it. Range Limiting Device - This CYBEX patented technology adjusts the machine to the user rather than the user to the machine. Regardless of the starting position selected, the cam remains synchronized with each individual user. RLD varies the leverage to maintain the correct level of force throughout the range of motion while taking into account each user's limits and abilities. Start RLD (adjustable start only) provides start positions every 10 degrees. Total RLD (adjustable start and finish) provides start and end positions every 10 degrees which is ideal for physical therapy in that it stops users before internal stress is too high. Eagle offers Start RLD as a standard feature and Total RLD is available as an optional feature.

All-around thumbs up!
Size: 934W-Z, Color: Black
So far, so awesome. Easy to assemble, comfortable, arrived quickly and is exactly what I was looking for. I have a tall work bench in my new studio so I needed a chair that we could allow me to sit higher than a regular office chair and allow me to get off my feet after standing on the concrete floor. Plus its a nice looking chair that I am sure will last a long time. I love the flip-up arms and the lumbar support. This is just right!

Perfect Balance of Comfort, Support, and Style!
Size: 934-Z, Color: Black, Size: 934-Z, Color: Black
I’ve been using this chair for a few weeks now, and I’m genuinely impressed with how much of a difference it’s made in my workspace. The mesh back is one of my favorite features—it offers excellent breathability and prevents that sticky, overheated feeling you sometimes get with solid-back chairs, even after sitting for hours. The seat cushion is firm enough to give proper support but still has enough give to keep me comfortable through long workdays. It feels like the perfect middle ground between soft and supportive. The adjustable foot ring has been a complete game changer for me. I use a taller desk setup, and having somewhere to rest my feet makes a huge difference in posture and overall comfort. Whether I’m sitting upright for focused work or leaning back to read, it’s always at the right height. The flip-up armrests are another smart design choice. When I’m typing, I like to have them down for support, but when I’m done, I can flip them up and push the chair neatly under my desk—saving space and keeping things tidy. The casters roll smoothly on both hardwood and rugs, so I can move around easily without scraping the floor or getting stuck. The overall build quality feels solid and sturdy, with no wobbles or creaks. Assembly was surprisingly quick—everything was clearly labeled, the parts felt durable, and it only took me about 20 minutes from opening the box to sitting in the chair. The sleek, modern look is another big plus—it blends in perfectly with my home office décor without feeling bulky or taking up too much visual space. If you’re looking for a chair that combines comfort, ergonomic support, durability, and style, I can’t recommend this one enough. It’s equally great for work, studying, or just relaxing at your desk, and it’s definitely been worth every penny.

OK for the price, but overall comfort is avergae
Size: 934-Z, Color: Mustard
Easy to put together, color (mustard) accurate to images, and while I understand this is not a high-end chair, I feel like it still needs to be rated for its quality. Pros: the seat cushions are fairly comfortable and it rolls well. Adjustable footrest is easy enough and mostly sturdy. Cons: For a tall office chair, it doesn't go up high enough. I actually had to lower my standing desk to sit at it, which then isn't where I want it when I'm standing now. It's also a bit wobbly. The seat area's attachment to the post isn't as solid as it should be for a tall chair, so while sitting, it does tend to lean/slope forward and wobble side to side. The lumbar support is not adjustable, so I'm not even really sure what it does. And the armrests are not very comfortable to use. Since they are hard plastic, they are just a bit too rigid to rely on for any comfort. They are basically there to hold on to when you're getting out of the chair.

Good Value for a Tall Chair
Size: 934W-Z, Color: White
I have received this chair just today and would like to give my first impressions of it. Height is super adjustable as well as the foot rest. My desk is very tall (~34 inches vs standard ~29 inches) and does not suit a standard height chair. This chair's height is enough to sit comfortably at mybut also still having adjustment to be even higher. Lumbar support is a manual adjustment that can be adjusted by sliding the lumbar piece up or down and it seems it can be tiled as well. No reclining feature or slight backrest tilt adjustment. I'm used to my chairs reclining so it feels a little awkward siting in a flat base and straight backrest. I feel like I'm sitting too forward or leaning forward slightly but is probably something I can get use to. Easy to put together and feels very sturdy. Plastic parts of chair are made from a really sturdy plastic, like playhouse plastic materials. Wheels roll around carpet easily. Mesh seems to be a strong material, though the mesh feels kind itchy on bare skin. Overall, I think this is a good chair to get if you're needing a tall chair for a good value and can sacrifice no backrest tilt.

Excellent value for money!
Size: 934W-Z, Color: Black, Size: 934W-Z, Color: Black
I absolutely love this office chair! I needed a chair that could support my standing desk without sacrificing comfort, and this one completely exceeded my expectations. It's incredibly sturdy and durable, well-made, and the height adjustment is super convenient, making it easy to find the perfect fit. Even during long hours of work, the seat is comfortable, and the ergonomic design effectively reduces pressure on my back and legs. I love its clean, modern look—it fits my home office perfectly. Assembly was quick and easy, and for this price, the quality is absolutely fantastic!
