US Patent 11,700,947

One frame. Chair, bench, decline, and three incline positions.

FitChair is a comfortable rolling office chair that converts, tool-free, into a gym-grade exercise bench. One piece of furniture for the room where you work and the room where you train, because for most people that is now the same room.

The simple idea

Your office chair is also your home gym.

Most people who work from home and want to train at home don't have room for both an office chair and a full weight bench. So they pick one and give up the other. FitChair is one rolling frame that is genuinely both: a chair you sit in all day, and a bench you train on. Nothing to stow, nothing to assemble each time, no tools to swap.

Concept visualizations of the design.

Two real products, one frame

Not a chair pretending to be a bench, or a bench pretending to be a chair. Seated, it is a comfortable rolling office chair. Converted, it is a gym-grade exercise bench. The same frame becomes either one.

No compromises

Six positions in all: the chair, a flat bench, three incline angles, and a decline. Every change is tool-free and locks in place. Surfaces are water-resistant and sweat-cleanable, and the base stays planted under load.

It belongs in a living room

FitChair reads as furniture, not gym equipment. It rolls on casters, ships in a box instead of on a pallet, and replaces an office chair, a flat bench, an incline bench, and a decline attachment all at once.

The story behind FitChair

Two industries didn't notice they had become the same room.

The home-fitness industry built better and better adjustable benches, assuming customers would put them in basements or garages. The office-furniture industry built better and better chairs, assuming customers would buy them for offices. Then millions of people found themselves with one room that had to be both.

The customer who wants to lift at home wants a real bench: not a flat-and-incline-only compromise, not a folding bench that gets stowed and forgotten. A bench that handles flat, three incline angles, and decline, the way a gym bench does.

The same customer wants a chair to work in all day. Comfortable seat depth, adjustable backrest, armrests, mobility. Furniture that belongs in a living space.

FitChair resolves both roles in one rolling frame. The chair mode is not a compromised bench. The bench mode is not a reinforced chair. A patented mechanical assembly makes both work from one base.

See it convert

One frame moving through every position.

Chair to flat bench, up through 45°, 75°, and 90°, and down into decline. Every transition is tool-free, with nothing to detach.

The conversion sequence, shown through the actual prototype renders: chair, flat bench, 45°, 75°, 90°, and decline.

How it started

How FitChair started.

Before the pandemic, I had a full gym in our garage. I loved it. Early in the morning or after a long day at work, that was my place to work out and recharge.

As our family grew, we needed more space, so we turned the garage into a home office and laundry room. Not long after, the pandemic arrived and I found myself working from home every day.

One afternoon, after sitting at my desk for hours, I caught myself missing my old garage gym. Then a simple thought popped into my head:

What if this office chair could also become a workout bench?

What if it could recline into different positions, add a little extra support, and let you get a real workout without needing a separate room full of equipment?

The idea felt exciting right away. A chair for work when you need it, and a workout bench when you want it.

That simple idea became FitChair.

The images below are some of the very first concepts and renders I created. Looking back, they were rough and simple, but they started the journey that eventually led to the FitChair you see today.

Design progression

From first concept to V3.

FitChair went through four design generations. V1, V2, and V3 were each built as working prototypes. V0 was the original concept, never physically made. Each step refined the frame, comfort, the folding mechanism, and the materials.
