The shade of gray is not as depicted in the photos, it is more of a light gray (not dark).
The quality is quite good, compared to some much cheaper covers I had, there is a noticeable difference.
The texture reminds me of something in between terry cloth and velvet.
They do not have a hole for side airbags in the seat.
The hooks provided in the package are plastic (thick plastic).
In a Nissan Micra K12 (2002 - 2010), the front covers fit quite well and the rear ones slightly worse.
Also, the rear covers do not have holes for headrests, so anyone who wants to put them on will have to open holes themselves (ouch)..
I can't say I was thrilled about their price, but they are definitely of good quality.
