Based on what I observed, there are vinyl out there that may warp over time. My friend used it for th bedrooms and he regretted it. 2 issues with it,
1) Warped vinyl flooring - the edges of the vinyl starts bend outwards, which causes it to pop out and may occasionally cause him to kick it which is quite painful. This problem only surfaced after a year or 2 if I recalled wrongly.
2) Some vinyl have rough textures. He found it very difficult to mop the floor, especially he chose the rough type to minimise slippery floor. Mop always rubbed on the rough floor causing dirt and even the fabric on the mop to get stuck.
Price and quality of vinyl flooring vary wildly, that's the problem. Which brand did your friend use?
