Antlu Saddle Stool Rolling Chair Review: Ergonomic Seating for Better Posture

Does your office chair leave you slumped over your desk with aching posture by end of day? The Antlu Saddle Stool Rolling Chair takes a different approach to ergonomic seating.

This saddle stool features a distinctive design that spreads your legs and opens your hips, naturally encouraging an upright spine position. I’ve been testing this chair for months in my home office, and the results surprised me.

With a 400 lb weight capacity, metal base construction, and height adjustment from 21 to 28 inches, the Antlu is built for serious daily use. It rolls smoothly on carpet and hard floors alike, with a 360-degree swivel and leather-like cushion that holds up well.

The stool has earned a 4.3 rating from over 3,600 Amazon reviewers, and independent testing rates it 8.6 out of 10—surprisingly higher than some chairs costing ten times as much. Here’s what I found after putting it through its paces.

What I Liked

Improved Posture and Spine Alignment

The saddle chair design fundamentally changes how you sit. Unlike a traditional office chair where your feet are out front and your hips are closed, the Antlu spreads your legs into a straddle position that opens your pelvis.

This might sound awkward, but the effect is remarkable. My spine naturally aligns into an upright position without effort. It would feel strange to hunch over in this chair—the geometry works against bad posture.

Thick Cushion for Extra Comfort

Many saddle stools have thin, hard seats that get uncomfortable quickly. The Antlu takes a different approach with a seat cushion that’s notably thicker than conventional saddle stool designs.

The cushion strikes a good balance—not too firm, not too soft. It provides support without bottoming out, even during longer sessions. The faux leather surface feels quality and cleans easily.

Smooth Rolling on Any Surface

The five caster wheels roll extremely well on every surface I tested. Carpet presented no resistance at all, and tile floors were equally smooth.

I can spin a full 360 degrees and scoot across my office floor without any of the dragging or stuttering common in cheaper chairs. The wheels haven’t marked up my hardwood floors either.

Wide Height Adjustment Range

The hydraulic lift adjusts from 21 to 28 inches—about 4 inches taller than regular stools. This extended range matters if you use a standing desk or work at a higher surface.

The adjustment mechanism is smooth and responsive. No pressure spikes or sudden drops when raising or lowering the seat.

Sturdy Metal Base Construction

Where many budget stools cut corners with plastic bases, the Antlu uses a metal frame throughout. The difference is immediately apparent when you sit down—there’s no flex or wobble.

The 400 lb weight capacity reflects this solid construction. The stool feels built to last through years of daily use in demanding environments like salons, clinics, or home offices.

What Needs Improvement

Narrow Seat Width for Larger Users

The saddle seat design requires a narrower profile to achieve the leg-spread position that improves posture. However, this creates a tradeoff—users with larger frames may find the seat uncomfortably narrow.

Several reviewers with bigger builds reported the seat doesn’t accommodate them well. If you have wider hips or thighs, test before committing or consider alternatives.

No Backrest for Passive Support

The base Antlu model has no backrest option. This is intentional—the design encourages active sitting and core engagement rather than leaning back.

For users with existing back conditions who need passive lumbar support, this could be problematic. The chair works your postural muscles rather than supporting them.

Adjustment Period Required

Switching from a traditional chair to a saddle stool isn’t instant. Your body needs time to adapt to the new sitting posture.

I found about three quarters of my workday was comfortable on the saddle stool from the start. After that, I’d feel restless and want to switch to a regular chair. Some users report needing to massage their back after the first day. This isn’t pain—just muscles adapting to a new position. Most users adjust within a week or two of regular use.

How It Compares

The saddle stool market ranges from budget options under $100 to premium chairs over $1,000. The Antlu positions itself as a mid-range option that punches above its price.

HAG Capisco - The Norwegian-made Capisco is the gold standard for saddle chairs at over $1,000. In independent testing, the Antlu scored 8.6 out of 10 compared to the Capisco’s 8.5—a surprising result given the massive price gap. The Capisco offers more adjustability and a T-shaped backrest, but for basic saddle stool functionality, the Antlu delivers comparable ergonomic benefits.

FRNIAMC Saddle Chair - This competitor includes built-in back support at a similar price point. However, it scored 7.6 out of 10 in the same testing, primarily due to adjustment period discomfort and less refined finish quality. If you need a backrest, the FRNIAMC is worth considering despite the lower rating.

Kaleurrier Saddle Stool - A direct competitor with 4.6 stars from over 950 reviews. The key difference is weight capacity: Kaleurrier supports 350 lbs versus the Antlu’s 400 lbs. Both lack backrests and share similar narrow seat concerns. The Antlu’s stronger build makes it better for heavier users.

For home office use with a standing desk setup, the Antlu offers the best combination of build quality, ergonomics, and value. Premium alternatives justify their cost only if you need specific adjustability features or all-day seating capability.

Final Verdict

The Antlu Saddle Stool Rolling Chair earns a 4.1 out of 5 rating. It delivers genuine ergonomic benefits at a fraction of what premium saddle chairs cost.

The saddle design does what it promises—it naturally encourages better posture by opening your hips and aligning your spine. The build quality exceeds expectations for this price range, with a sturdy metal base and comfortable cushion that holds up to daily use.

The limitations are real but predictable for this category: no backrest, narrow seat for larger users, and an adjustment period when switching from traditional chairs. None of these are dealbreakers if you understand what you’re buying.

For home office workers, healthcare professionals, or anyone seeking active seating without the premium price tag, the Antlu represents excellent value. It scored higher in independent testing than chairs costing ten times as much. That’s a compelling argument for giving saddle stool seating a try.
