Adjustable Height Desk ODP10557

I've never seen another one with the concave front like the (what I think is the) original Costco offering. I'm sorry that is no longer a feature.

My chargers are long gone but I'm married to the curve.

I don't think I can add anything meaningful. It's just marginally cozier feeling than a flat surface to me.

Costco has one by Tresanti that I've had for three years at this point. It's 47", so sliiiightly smaller than your requirements but otherwise it's been a perfectly reasonable desk. ...I previously had a more expensive Uplift desk that was just too dang big (not their fault; mine). Despite being sub-$300, the Tresanti has been just fine. It's fine. It's not amazing, but it is perfectly reasonable and very affordable. In fairness, I probably adjust the height only twice a week or so, YMMV.

I have the older version (no cool lights) from Costco and love it. A coworker recommended it to me and my husband wants to get one too - so they're loved by many! I want to say it was under $300 in the warehouse.

I got a Flexispot on a Black Friday sale and saved about a hundred, honestly pretty sturdy depending on how detail oriented and handy you are with assembly. There's one through Costco that doesn't look half bad that has a glass top, USB-A X1 + USB-C X2 integrated charging ports on the side, and drawer. Though I prefer a wooden top to secure a multi-monitor mount and install cable management.
