I'll call it 4.5. For the $62 I paid it's a pretty decent chair. I got this to replace a 10 year old, slightly cheaper mesh-backed chair. Because of it's age, the seat padding thinned out and you could feel the seat bolts in your butt. I like to sit on my feet and had many times where that bolt went full force into the top of my foot. I wanted a white chair to match my desk which is an IKEA Kallax/Linnmon combo. The chair doesn't match it exactly but that's not a big deal. Some people had issues with staining. I have a pair of Uniqlo jeans that stain and they've not stained this chair--however I've also been cautious of that when I sit on it. I use it about 3-4 hours a day on average. The chair can be adjusted to higher height at my desk which I like, and there's enough room on the seat and back. It does have a minor chemical odor when it comes out of the box, but that dissipates after a day or two. The wheels are nice and roll around with ease, not even getting stuck on my area rug. The seat/back padding is thick and soft, with a slight underlying firmness. I give it a 4.5 because the edge piece (the silver border you can see in the photos that goes around the seat and the back) doesn't connect, and the piece is a little wavy. I get that in construction of this type of chair there would have to a break with that band, but it's a slight noticeable gap. The wavy-ness I guess is due to the fact that this band seems to be malleable. This is not a huge deal, just something noticeable, and doesn't affect the comfort level of the chair, which is good. Edit: I accidentally got a little bit of pen mark on the front-center of the seat. I tried cleaning with water, Scrubbing Bubbles, Oxi-Clean, Shout, Nail Polish Remover, and Tilex because there were no bad ideas. The stain has faded but isn't totally removed; the nail polish remove seemed to be the most effective. That said, during the Scrubbing Bubbles treatment I was wiping it a little hard so I may have set it in. It'll probably fade out over time as it's right under where my legs go on the seat. Edit 2: Over a few weeks to couple months, that pen mark has 99% disappeared. If I look really hard, because I know where it is, I can barely make it out. If you didn't know it was there before, you wouldn't see it now. Edit 3: 16 months with the chair and it's still great and still white, with only the faintest, barely noticeable wear and tear discoloration on the seat. I'm talking the back is 99-100% as it was out of the box, and the seat is maybe 90-95%. No other issues with the chair. Edit 4: Just passed two years with the chair. The seat portion has a tiny bit of grey-ish discoloration form all the use and some minor material cracking started at two areas on the seat. I also got another accidental pen mark on the chair, this time on the side. Like the other mark it's fading but not as fast as the other one due this one's less touched location. Edit 5: Four years with the chair. The back is 98% good, very faint cracking is starting. The seat is only 45-50% good now, lots of cracking where my butt and legs normally lie on it but it's still somewhat soft. I've been thinking about maybe replacing it but as of this writing it's now $116, not worth it at that price.
