Does anyone have carpet tile in their home? DH saw it on HGTV and we're thinking of getting it for the nursery. I found it at Home Depot and it's not as expensive as I thought it would be!

So here are some of my questions:
Was it easy to install (we'd be getting the non-adhesive kind)?
What brand/where did you buy it?
How has it worn?
Do they come up when you walk on it if you get the non adhesive kind?

Thank you in advance for your help!
