I ordered this for 2 rooms at my church - the nursery, and a children's sunday school room. The old broadloom wall-to-wall was getting tired in both rooms. Carpet tile costs more, but the benefit of spot cleaning/replacing seems so worth it, especially for these rooms which want to be clean, but quickly get dirty - and the kids like to play on the floor. Working with the Christian Ed director (my wife), we chose something loud and playful, that would also help hide dirt.
The other fun thing we did was install the carpet in one room with quarter turns, and the other room like a brick running bond, stripes all going one direction. Two different looks with the same carpet.
No glue-down made install easy.
