Yes, you can sit cross-legged in some ergonomic chairs if the design with the depth as well as width of the chair's seat allows. It is possible to sit comfortably cross-legged on the right ergonomic chair from time to time though it is not ideal for long periods.
Many of the people will naturally shift their positions while they are seated. This adjustment can make crossing of your legs feel like a moment of relief. A good ergonomic chair won’t force rigid stillness, but it will give freedom for movement while offering support to your core.
Seat design matters if you want to sit cross-legged
To sit cross-legged comfortably, you'll need a wide, deep seat without obstructions such as fixed armrests or hard seat edges.
Not all ergonomic chairs have design so. Some chairs have narrower seats including firm side supports. Therefore, sitting cross-legged feels unstable or cramped. However other models offer sufficient space as well as flexibility for shifting into this position from time to time. Especially models with waterfall seat edges and adjustable armrests accommodate shifting during use.
For any chair that you sit in this way quite often, look for some fabric or some mesh upholstery, minimal contouring, and a wide seat base. Without any discomfort, these features can make repositioning of your legs easier.
Use it as a temporary position, not a permanent one
While sitting cross-legged might feel cozy for a while, it’s not the best position for your posture or circulation long-term. Ergonomic chairs are built to support a neutral sitting position where both feet are flat on the floor.
That said, it’s totally okay to shift into a cross-legged position from time to time, especially when your body needs a break from the usual. Just be sure to return to a supported sitting position with both feet down for most of your workday.
An ergonomic chair gives you the flexibility to move and reset, that’s part of what makes it so effective. So yes, you can sit cross-legged in the right ergonomic chair, if it’s done in moderation and the chair supports it comfortably.
