Ergonomic Stool for Active Workspaces

The MI-931 provides a dynamic seating option for home offices, studios, or clinical spaces. Its height range of 24.8" to 34.6" supports both sitting and standing postures. The 360° tilt mechanism encourages continuous micro-movement throughout the day. A 248 lbs weight capacity accommodates a broad range of users.

Tool-Free Integration and Mobility

Assembly requires zero tools, so the stool is ready for immediate use on any level floor. Integrated side handles allow quick repositioning between workstations without lifting strain. The compact footprint fits beneath standard desks or counters when not in use. No external power, gas lifts, or floor anchors are needed for operation.

High-Density Foam Cushion and Range Limits

The premium foam seat balances firmness and softness for extended sessions of drawing, typing, or detailed tasks. Height adjustment tops out at 34.6", which may not suit users requiring taller perching positions. The fixed 360° tilt base offers no lockable angle settings for static support. Buyers needing a backrest or armrests should consider alternative seating styles.

Questions about this item

How much weight can the MI-931 stool support before the base or lift mechanism reaches its limit?

The stool is rated for a maximum load of 248 lbs, so the structure and height-adjustment system are designed to handle that weight during sustained use.

Does the seat stay cool and quiet when I lean on it all day at a standing desk?

The high-density foam cushion and non-slip base have no moving fans or motors, so the stool remains silent and does not generate heat during continuous use.

What tools or extra parts do I need to assemble the MI-931 before I can use it?

No tools are required; the stool ships ready for tool-free assembly using only the components included in the box.
