This invariably arises in low cost office seating. Unlike metal springs the foam doesn't just fail from a single overloading. Instead what happens is that it gradually deteriorates over time through repeated use. The bad news is we are usually talking of a few months rather than years.
And this is why it's so easy to be lured into a false impression about the comfort of an Office Chairs Singapore. Of course it all feels great when you try it out. It takes more than a few quick sessions of sitting by showroom visitors to expose its true colors.
It's only when you start using it for hours at as time that the foam gets put through its paces and its shortcomings become apparent. Over a period of a few months cheap foam starts to breakdown as it tries to support a load it was never designed for. It rapidly loses all its resilience and ends up flat and hard.
