Most people buy a console for the look, but forget the load. It is not just about looks, and a 75-inch TV is not light. That weight presses down hard on the middle shelf. If the wood is thin, it cracks. Solid wood is better than particleboard, so avoid very cheap plastic legs. This one damn sturdy.
You must check the floor too. Many Singapore flats have uneven surfaces. Older blocks settle more really. A console sits on four legs, but if the ground is not flat, it rocks. Adjustable feet help fix this lah. Some units come with them already. If you bring it home and it wobbles, you cannot fix it later. Use a spirit level to be sure.
TV consoles come in lengths. 120cm fits 55-inch. 240cm fits 75-inch. If you put a big screen on a small cabinet, it tips. The centre of gravity shifts. Check the depth too. A shallow console makes the TV look like it is falling forward. Anchor it to the wall if possible. Even if it stands on the floor, securing the back prevents toppling when kids push or pets jump, which happens quite often in many households and keeps everyone safe. Make sure the wall is solid before drilling properly. Do not always ignore this advice.
