Seems sturdy, be careful on size of TV / bottom clearance.
Had a 40 inch TV. Ordered this stand as title and specifications state it supports up to a 42 inch TV. The manual in the box only says up to 37 inches. Even the linked manual online, in the description for the product, says Max 37".On my TV, the feet of the stand would not clear the bottom of the TV. I was able to get around this by 'extending' the back arms off the legs; using only one of those attachment points rather than both. It is currently working OK, but I will be wall mounting this TV in the future and will use these legs somewhere else or just garbage them.
These mounting brackets are high quality, heavy duty. I installed them on a vesa 32" Samsung TV and placed them in a narrower space. The length of the brackets made stability a plus. Very pleased with this purchase.
Allows the end user to install the brackets on a wider TV. Stability is not an issue.
I use for replacing lost legs for customers removing tvs from wall mounts. It also works on some mantle placed tvs due to the factory legs often stick out too far on the front causing a falling hazard.
