Sitting School
Sit Better. Breathe Easier. Work Longer—Comfortably.
Master posture on Björn Saddle Stools and the Bruno Ergo-Eco chair. This quick guide shows ideal angles, adjustments, and pro tips—plus two short videos to help you feel the setup immediately.
Björn Saddle Stools
Ease In: Limit sessions to 45–60 minutes initially; stand, stretch, breathe.
“Try not to sit for more than 45 to 60 minutes before taking a break. Get up, stretch … take a deep breath!”
How to Get Seated
Mount: Grab the front of the saddle and mount from behind. If too high, lean on the seat to lower.
Seat Height (Left Lever): Pull up and raise/lower until you reach the ~45° leg angle. Release to lock.
Tilt (Right Lever): Hold lever up and lift the saddle nose to level (0°). From level, add a gentle forward tilt to discourage slouching.
Foot Position: Keep feet slightly behind you; align heel–hip–shoulder vertically.
For Classic 400/500 (male users): A slight forward tilt can reduce pressure on the genitals.
Sitting Low: If legs are <45°, move feet back under the seat to restore the angle. A touch of forward tilt also helps. Even with one foot forward (e.g., to operate controls) your posture can stay upright.
Stand/Sit Mode: Raise the stool to just below standing height and add a mild forward tilt to take weight off feet while maintaining posture.
Break rhythm: every 45–60 minutes, stand, stretch, and reset.
Bruno Ergo-Eco Office/Work Chair
Starting Position: Turn the chair-adjustment lever forward to fully vertical. Sit with your buttocks all the way back. Lean into the backrest to bring seat and back to an upright position.
Seat Height: Turn the lever slightly backward while lifting/lowering to your height. Aim for knees 2–3″ lower than hips and a slight seat tilt to reduce thigh pressure and preserve your back’s natural S-curve.
Backrest Height: Pull up the lever on the backrest to unlock, then position the lumbar pad in the small of your back. A 5° forward twist of the chair-adjustment lever isolates backrest-only adjustment.
Seat Tilt: Turn the lever past 45° and lean forward to set seat tilt. Lock when thigh pressure feels minimal (re-tune backrest after tilt).
Free-Float Mode: Set the lever to the all-forward vertical position to let the backrest move with you for continuous lumbar support and gentle back-strengthening micro-movement.
Try not to sit for more than 45–60 minutes without a break. Stand, stretch, breathe.
Quick-Fit Checklist (60-Second Setup)
- Seat Height: Thighs sloping ~45° down to the floor; hips above knees.
- Torso Angle: ~135° torso-to-thigh (open ribcage, easy breathing).
- Feet: Slightly behind your hips; align heel–hip–shoulder vertically.
- Tilt: Start level (0°), then add a mild forward tilt to prevent slouching.
- Space: Legs ~90° apart for a stable base and free hip rotation.
Tip: If pressure at the front of the saddle occurs (esp. male users on Classic 400/500), add a little more forward tilt.
7-Day Adaptation Plan
- Days 1–2: 30–45 min sessions, 2–3×/day. Focus on height + gentle tilt.
- Days 3–4: 45–60 min sessions. Add light core engagement (ribcage tall).
- Days 5–6: Up to 90 min blocks. Practice reaching while keeping spine long.
- Day 7: Normal work blocks with scheduled breaks (see routine).
Mild glute/low-back muscle awareness is normal and should subside as stabilizers strengthen.
“30-60-3” Micro-Break Routine
- Every 30 min: 30-second posture reset (stand, shoulder rolls, deep breath).
- Every 60 min: 60-second hip hinge + calf/hip flexor stretch.
- Every 3 hrs: 3-minute walk: shake out hands, gentle side bends.
Common Mistakes & Quick Fixes
Mistake
- Seat too low (hips ≈ knees)
- Feet far forward under the knees
- Excessive forward tilt
- Knees too close together
- Slouching to reach
Fix
- Raise seat until hips are clearly above knees.
- Bring feet slightly behind hips; stack heel–hip–shoulder.
- Return to level, then re-add a small forward tilt.
- Open stance toward ~90° for a stable pelvis.
- Bring task toward you; keep ribcage tall and shoulders wide.
Troubleshooting Comfort
Pressure at Front
- Add slight forward tilt; verify 45° thigh angle.
- Scoot back fully on the saddle to widen contact.
Low-Back Fatigue
- Raise seat 1–2 cm and re-stack heel–hip–shoulder.
- Use shorter work blocks for 2–3 days while adapting.
When to reassess: If discomfort persists beyond two weeks, re-check height/tilt and stance width or contact support for a personalized fit.
FAQs
How high should the seat be?
Set hips above knees with thighs sloping ~45° down to the floor. If your ribs feel compressed, the seat is likely too low.
What tilt should I use?
Start level (0°), then add a gentle forward tilt—just enough to discourage slouching and relieve front-of-saddle pressure.
Is discomfort normal at first?
Yes—mild muscle soreness is common for 3–7 days as stabilizers adapt. Use shorter blocks and micro-breaks during this period.
Can I work nearly standing?
Yes. Use “stand/sit” height (just below standing) with a light forward tilt to unload feet while keeping posture tall.
