Question: Is the entire thing really 20.5 inches tall?  From the floor to where the TV sits on top?  Also, how many inches is the open space on the top?
Document: This TV stand works very well for my apartment. Way better than what i was using before. It's very easy to assemble. I put this together in about 20 mins. It holds the WiiU, PS3, Xbox 360 and a power strip. None of my consuls heat up enough to freeze anymore because of the top space between the cabinets and the TV itself. I am very pleased with this product and would definitely recommend for the price it was selling for. Its very sturdy also.
I knew (especially after reading the reviews) that I would be getting a product in the middle of the TV stand spectrum; you should realize that for the price you're paying. I knew the doors were cheap plastic, and that doesn't bother me. Yeah, glass or wood would be nice, but honestly, I think the doors look great. You can't really tell that they're cheap until you open them, so they're not an eyesore. It also helps keep the stand very light.
got this TV stand for my new LG 55LM6200. the TV fits almost perfectly on this stand. it sticks out half an inch on both sides of the stand, not a big issue. i also like the open area where i placed my ps3. i didn't want one of those stands with all enclosed areas because the heat radiated from my ps3 (or dvd/bluray players etc.) needs a place to go. if you trap the heat it will eventually over heat.
Most furniture is made of this stuff, unless it is high end. It is not bad, and you probably own furniture made of this already.The 5 posts that you see on the picture that hold the top board where the TV would sit on, to the bottom portion are made of plastic. they look metal, but they are plastic. I am NOT afraid that these will not hold. They are pretty solid.
It looks nice from the picture but really you have to be that cheap to make it with plastic doors. I was expecting wood doors but when I got it it came with plastic. And another thing is the directions on it was so hard to follow wouldn't get it
Sits lower than I expected. Should have checked measurements. Also side doors are very flimsy cheap plastic. It works to have something to put your tv on.
The product is okay, however, the lower storage is a bit too low to access. Also, there could be another additional 3&#34;-4&#34; space where the DVD, etc., would sit.
Peices of the top black surface came off when putting on the right lower side panel. Also bows a little with 50" plasma tv on it.
Good : Plenty of space, easy to put together, price well worth itOther : Doors are plastic but if you are not close to it you cant tell. Also one door tends to close easier than the other but its things that can be overlookedDefinitely recommend for those just looking for a sturdy place to set a t.v
I really thought it would be better but its such cheap material. And I cant believe the doors are plastic, almost like the plastic that you need scissors or a knife to cut through when you purchase expensive items. I couldnt believe it. Dont waste your money and time. Also, putting it together was hell along with instructions that made absolutely no sense.
Answer: Yes it is 20.5 inches tall from the floor. The opening is 7 3/4 inches. Plenty of room for cable boxes and some surround sounds.
