What We Liked

The WL-SB-101-GG has a wood x-shaped base with 4 casters. After 10 minutes of use, I noticed the seat tilting – the screws were coming loose. The replacement didn’t have this issue. Casters have an angled mount similar to the 1420. Near-nonexistent padding with uncomfortable fabric. Two products on this list I do not recommend buying – this is one of them.

Compare The 10 Best Knee Chairs for 2025

Why Trust The Breakroom Blog?

Simply put, we are experts. We have been selling office furniture for 12 years and have seen the sit-stand desk market grow from the beginning. We are not a company that is simply dedicated to writing reviews on emerging markets in hopes of making a quick buck. Office furniture is our life and we have gained extensive knowledge about the products within our space.

One thing that really separates The Breakroom Blog from almost every other review site is that we bring in all the products that we review. We do not do forensic reviews or reviews based on what other customers have said about the product. We order the product for ourselves so that we know how it performs. Some of the products we sell on BTOD.com, but many we do not. Regardless, we have tested every product we have reviewed.

What Was Our Testing Process?

We placed orders for all the chairs on this list. When the chairs arrived, we evaluated their packaging and noted any concerns. After unpackaging, we assembled them and looked for pain points. After assembly, we brought each chair to the middle of our office to get a general reaction from everyone. I left each chair out for a week or so to let people try it out and get feedback.

I also put significant personal time into each chair. If the chair had adjustments, I used it at various heights and angles. I paid close attention to padding comfort and how long I could stay in each chair before getting uncomfortable. I also evaluated range of motion and sitting mobility. After enough time to form a confident opinion, I moved to the next model.

How Did We Pick the Best Kneeling Chair for 2025?

After testing all the chairs, I ranked and scored them across six categories, each scored 0-100 and weighted equally. These six categories are what we feel are the most important factors when shopping for a kneeling chair.

Build Quality – Frame, adjustment mechanism, padding, fabric, and casters. Lowest scores for the most low-end components; highest for the best materials and adjustment systems.

Warranty – Length of coverage and number of exclusions. Most exclusions and shortest coverage = lowest score.

Mobility – Ability to move the chair while sitting in it. Low-quality casters with poor frame designs received the lowest scores; 5-star bases with quality casters received the highest.

Seat Comfort – Size, shape, padding, fabric quality, and how long I could sit before getting uncomfortable.

Knee/Shin Comfort – Padding, fabric, size, longevity, pad angle, and adjustability. Models placing weight on the knees rather than shins received lower scores.

Range of Motion – Ability to move your body actively while seated. Rigid frames that lock you in place scored lowest; flexible sled-based designs scored highest.

What Did I Learn About Kneeling Chairs?

Testing these products taught me a lot. Being able to go back and forth between models to compare specific aspects was extremely helpful. Here are the key learnings that may help you while shopping.

There Are 3 Basic Kneeling Chair Designs

All the kneeling chairs I researched fall under one of three categories: sled-based, x-base with casters, or 5-star base with casters.

Sled-based models are made from wood and feature individual knee pads. The sled design allows you to rock back and forth. The wood frames flex, allowing a wide range of motion on top of the rocking ability. The one downside is lower sitting mobility than the other designs.

X-base models function like a pair of scissors. A cylinder placed toward the middle makes the x larger or smaller for seat height adjustment – either a manual hand crank or a pneumatic lift. Frames may be steel or wood, and all tested x-base models featured four casters.

5-star models have bases designed like normal office chairs. They have five quality wheels and pneumatic cylinders for easy height adjustment. The frame has a metal bar extending below the seat to hold the knee pads. These chairs can swivel but otherwise provide no additional range of motion.

Movement Is Crucial for Comfort

Being able to move my body – not just the chair – was necessary for me to be comfortable for longer than 30-60 minutes. The x-base and 5-star base models are very rigid. The frames do not flex, so you are locked into the same position for the entire session. In many ways they are more restrictive than normal office chairs, which at least let you tap your legs or shift your weight. The flexible wood frame designs on sled-based models allow a lot of movement while seated. This is the biggest reason I was more comfortable in sled-based models.

Sitting Mobility

Chair mobility – your ability to move the chair around while sitting on it – matters most for small adjustments to get into the optimal typing position. The 5-star base models were most mobile, x-base models next, and sled-based models least. However, sled-based models can still be slid and swiveled with some leverage from the desk. Two x-base chairs (the 1420 and Flash WL-SB-101-GG) had such poor caster designs that they were nearly unusable.

Soreness When Starting Out

It is normal to experience some soreness when switching from a standard office chair to a kneeling chair. Most models don’t have armrests, so your shoulders and arms will adjust to the new posture. The new leg angle will also engage different muscles in your back, stomach, and legs. Shin soreness took me about two weeks to resolve. Work your way slowly into using it more – if you feel significant pain, take a day off before continuing.

Not for Big or Tall Users

Kneeling chairs are not a good option for big or tall users. All chairs tested have weight limits of 200 or 250 pounds. Seat height ranges are generally not adequate for users over 6’0″. Two people in our office at 6’2″ and 6’3″ did not feel comfortable in any of the kneelers.

What Is a Kneeling Chair?

In the 1970s, Hans Christian Mengshoel worked with Norwegian designers Oddvin Rykken, Peter Opsvik, and Svein Gusrud. They developed the first kneeling chair, known as the Balans. Kneeling chairs put your legs at a more open angle, sharing body weight between your shins and your seat. The design allows for a more upright position and is intended to reduce lower back strain by keeping the spine in a natural arch. Note: the pads are for your shins, not your knees. Understanding ergonomics principles helps explain why the open hip angle is beneficial for spinal alignment.

Final Thoughts

My biggest takeaway after testing 10 kneeling chairs is that you generally get what you pay for. The two highest-priced chairs are the two highest-ranked. If you plan to use a kneeling chair for many hours a day, invest in a sled-based model – the Thatsit Balans for the full experience, or the Variable Balans if budget is a concern. If you want an additional seating option to rotate into your day periodically, a mid-range option from the Boss B248 through Sleekform range will work. Avoid the 1420 and Flash WL-SB-101-GG entirely.
