Sitting for extended periods of time can be uncomfortable for our backs, especially for taller individuals. Long-term sitting can lead to back pain. Ergonomic chairs can make us more comfortable. According to Chloe Costigan, a former D1 athlete and current physical therapist, sitting for an extended period "makes certain muscles tight and others weak."
We've designed office chairs specifically for larger and taller individuals, based on designs for most adults. In this issue, we'll explain in detail how to choose the right chair and recommend several models.

Common Office Chair Issues for Tall and Heavy People
Seat Depth |
Taller and heavier people generally require a wider seat cushion to support their hips and thighs. |
Back Support |
If the back isn't long enough to support the entire back, especially the upper back and shoulders, a smaller office chair frame won't work well with the natural curves of your body. |
Armrest Height |
Tall people need sturdy armrests for support, but they shouldn't be too low, which can cause shoulder discomfort. |
Seat Height |
If the seat is too low, your calves won't be able to stretch, blood circulation will be poor, and numbness can occur over time. |
Weight Capacity |
The weight capacity of the office chair will determine how long you can use it. |

Key Features of Ergonomic Chairs for Large People
Ergonomic chairs designed specifically for larger individuals must offer both sturdiness and comfort.
Higher Backrest
Regardless of your height, an adjustable backrest supports your entire spine, including your neck, back, and tailbone, according to your height. This reduces back and neck pain.
Deeper Cushion
Generally speaking, the standard sitting position is about three finger widths between your knees and the seat cushion. An adjustable seat cushion allows you to adjust this position for optimal comfort, providing ample hip and thigh space.
Adjustable Seat Height
In the standard sitting position, your feet are flat on the floor, with your knees bent at a 90-degree angle. Therefore, an adjustable seat height can help you find a more comfortable sitting position, providing more leg room and comfort.
Adjustable Armrests
In the standard sitting position, your arms should be level with your computer. The armrests provide support for your arms and shoulders. Adjustable armrests can be adjusted in multiple directions to suit your sitting posture, providing a variety of support options.
Lumbar Support
Lumbar support is available in both adjustable and fixed configurations, and most Boulies chairs offer this feature. This allows users to tailor the support to their needs.
Forward Tilt
The seat and backrest of the Boulies OP300 and OP180 can both tilt forward and backward. If you prefer or need to sit forward for work, these two options can accommodate your needs.
Back Tilt
All Boulies chairs can tilt back up to 165°, allowing you to relax and work in one place. Adjusting the chair to your preferred sitting position allows for greater comfort and productivity.
Weight Capacity
The standard tray capacity of typical office chairs is 250 lbs, but the recommended weight capacity is significantly higher. We recommend a normal weight capacity to ensure you can use the chair for extended periods.
