Barefoot on a Cold Floor

...because I'm having the hardest time picking FLOR carpet tile for my bedroom!!  Last month I was looking at 4 yellow/off white color options and you all helped me get some samples, so they came and I was not impressed.  They looked like they belonged in a basement:

Just not right.... I had higher hopes for the top one, that larger, has yellow floral pattern - but the background color is just ick.

So I went back to the drawing board by myself and went safer.  Grays.  New samples:

You can't really tell from the small samples - in person either - so they weren't very helpful. Here are the 3 above options in the FLOR styled photos:

{#1 - Feelin' Groovy; #2 - Walk the Line; #3 - Two of Hue}

I'm leaning toward #2, the mixed thickness stripes (and laid all mix directions like that)....

What do you think? I know it's a lot of grey...
