I was hoping the foam would be more dense and better in quality. The upside is the foam is removable. At the end of the day, you get what you pay for.

Well received.
It seems like the product is not the same
Anyway, I will use it well.

Comfortable and work well

is too soft. unfortunately not usable

It looks thick, but there is almost no cushioning.
The resilience is weak, and it feels like sitting on a cushion when you sit on it.
