Is there any TV brand that has one central base rather than 2 legs on a 43" TV?

Sony - 48" Class - LED - 1080p - Smart - HDTV

It'll be difficult to find that. For people with a soundbar or device to hook up to the tv a pedestal base prevents that. Good luck.

I have a Vizio it has a central base

I don't think there are many but I did see this one. Search: Sony - 43" Class - LED - X800E Series - 2160p - Smart - 4K UHD TV with HDR I believe there is also a samsung model too at 43" with a single base but I don't think it's in stock at this best buy. Search: Samsung - 43" Class (42.5" Diag.) - LED - 1080p - Smart - HDTV Good luck. Hope you find what you are looking for.
