A good TV cabinet has weight to it. You set a remote down on top and it doesn't skitter off, you lean on it reaching for a cable and it doesn't rock. The doors close with a proper sound, not a hollow clatter, and the drawers glide instead of sticking halfway and making you yank. Open the back panel and there's actual room back there for the mess of wires and the router and the game console nobody wants to look at, not some decorative hole the size of a phone charger.
This piece works hardest in the room where everyone actually sits, the family room, the den, the basement that became a second living room sometime around 2020 and never went back. Low and long suits a room where people sprawl on the floor in front of it. Taller with closed storage suits a smaller apartment where it has to hide the console, the DVDs you swear you'll get rid of, and whatever game controllers are currently missing a battery cover. Where it falls apart is the house with a huge wall mounted screen and nothing underneath but a soundbar, that's not a cabinet situation, that's a floating shelf situation, and buying a long low cabinet for a room like that just gives you three feet of empty surface collecting junk mail and candles nobody lights. It's also the wrong move if your real problem is cord chaos behind a wall mounted TV, a cabinet on the floor doesn't fix cords running up a wall.
On color, I'll say the thing I always say and then back off it a little. A rich wood tone, walnut or a warm oak, reads as furniture and ages fine, it doesn't date the way a specific gray stain did around 2015. Black works if the room already has some color doing the talking elsewhere, a rug, art, anything, otherwise it goes a little funeral home. My mother's cabinet is the same beige as her walls and her couch and I have told her more than once that her TV looks like it's floating in oatmeal. If you want one bold thing in an otherwise calm room, this is a fair place to put it, a cabinet in a deep green or a rust color with brass pulls does more for a room than people give it credit for, and nobody clashes with a television.
The detail that makes one worth having is a cable cutout you don't have to fight, a clean opening in the back panel so the mess stays invisible and the whole thing still slides flush against the wall.
