On a bit of a budget? I shopped around for a few rugs and was about to give in and drop $350-500 since all the quality rugs seemed to cost around that much. Shopping on overstock.com I was always hesitant to pull the trigger without being able to first see the rug in person (how black is that black?).
Happened to be in an IKEA one day and just said screw it, I didn't need a fancy rug and this one looks passable. The black is SO black and my shadow detail improved immediately. The density of the fibers leaves something to be desired (its too sparse) but on the plus side they haven't been pulled out by my vacuum cleaner and it looks just like the day I bought it. I actually got two of the largest size and sewed them together to make one huge one.
For the price I couldn't beat it, and one day when I have a dedicated theater room in a house I own I'll install dark carpet from the get-go
As with most synthetic rugs, there is an odor (I think its the government required flame retardant) for the first few days after you unroll / unwrap it. Opening a window and just putting up with it for a few days was no big deal for me, and now it only smells if you stick your nose in the fibers.
