I just received 'Livyn' Vinyl Tile samples from Quickstep Uniclic.
They seem *really* tough. 4.5mm vinyl with uniclic joints. Look to be a good option if you need a thin but hardwearing floor.
Prices are just a bit large, mind - from about £30+ per sqm.
Left to right: Chestnut, Slate, Travertine.
The laminate uniclic can be relaid a couple of times without undue damage. This should be reusable more times. Worth a look,
