Katu VS traditional casters:
Traditional rubber casters are made of a very cheap, soft rubber which, after a short amount of time, peels and separates from the caster.
The Katu rubber PU is just soft enough, so it will never come off of the caster. Therefore, it will not scratch wood or any other type of flooring.
On traditional rubber casters, dirt from the floor sticks to the rubber very easily and is almost impossible to clean. Over time,the dirt becomes a hard layer and scratches floors.
The rubber PU of the Katu casters has the perfect balance, so dirt will not stick to it. If the casters come in contact with some dirt, they can simply be cleaned with a damp cloth.
The body of traditional caster are made of a very cheap plastic or nylon, causing them to break easily and shortens the life of the wheel.
The body of Katu casters are made of Nylon PA6, PA6 is the strongest plastic used for casters.
With Katu casters, you can forget about scratches, stuck wheels and noisy squeaks! Our rubber PU caster wheels are the best caster replacements for smooth rolling and protected floors, thats why we provide 5 years warranty

Most Helpful Customer Reviews
We just had new wood floors installed in our family room replacing laminate flooring. We have a desk chair that has the original casters that are plastic. The plastic casters always scratched the floor so we wanted to replace them with rubber to protect the new floor. The offering on replacement casters on Amazon is large and confusing so we started reading the reviews to see who is really happy with the new casters. We found the KATU product and the reviews were very good. After purchasing, we are very happy with the replacement casters. They roll over the floor very smooth and quietly and have never caused a scratch or a problem.
These wheels don't fit as replacements for my IKEA office chair. Both are 'standard' but apparently not the same standard. It's the diameter of the stem that's the problem. The wheel is the same size and the post the same length as the one I'm trying to replace ... and the diameter is just a smudge too big, but different enough I can't even push them in as a snug fit. It may be my chair is at 'fault' so giving three stars on the basis of the fact these look like they would be good if they fit.
Update: Apparently there are (at least) two standards; 'B' and 'K' stems. These are 'B', 7/16" diameter stem. Mine were 'K', 3/8". The problem was neither my chair nor the wheels (which appear to be solid) but rather the description is a little incomplete. Vendor has accepted them for full refund so I have no complaint and have upgraded my rating.
