FAQ:

Are they really soft wheels that won't scratch floors? Because they look no difference from hard plastic wheels currently on my chairs.
Yes, they are really soft wheels that won't scratch floors.
It's hard to tell soft or hard plastic wheels just by appearance. It should depend on their material.
The hardness of polyurethane (PU) is less than hardwood, and we use PU for the outer layer of wheels, so these wheels won't scratch hardwood floors.

Is it possible to buy chair casters which are totally made of soft plastic ?
No. No matter what type of office chair casters, they must use hard plastic such as nylon or Polypropylene (PP) for wheel body.
It's just like the spoke wheel in bicycle wheels, which is related with capacity to support weight.
So it will be unable to support chair's weight if casters which are totally made of soft plastic.

If all PU soft wheels are safe to hardwood floors, why should I choose your products ?
Although most of soft wheels are similar, the difference is the way to make wheels.
Most of PU soft wheels are made by traditional plastic injection way, but the PU layer of wheels will be easily come off after used for 2~3 years.
However, all PU chair wheels of ENJOY CASTER are made by new patent plastic injection way, which will greatly improve the adhesion between nylon body and PU layer, that's why we dare to provide 5-year warranty.
