I'll toss Staples on to there. I ordered a chair two years ago. Relatively modern website, free delivery, and it arrived earlier than anticipated with no damage. Just make sure you unsubscribe from their newsletter.
I've had nothing but excellent experiences ordering online from staples, although their email notifications leave something to be desired. I've learned to just trust that my package is actually on the way now, but usually I get the "your package has shipped" email some time after I actually get the package, if I get a notification at all.
I was surprised when I ordered from Staples.com a week or two ago. They have a top-tier e-commerce experience, fast shipping (I think my free one-day shipping was a temporary quarantine thing), and they seem to be better at packing than Amazon.
I also think they'll price-match.
