Question: So it is okay if my 50" TV overlaps on the swivel?  My base is 37" x 17.  It doesn't need to fit perfectly, just make sure it is evenly centered?
Document: I bought this after reading the reviews and feeling a little hesitant. Some other reviewers had commented that it was bulky or ugly or too noticable under their TVs. I am glad that I bought it anyway. Definitely pay attention to the dimensions posted and measure against your TV stand and TV set to make sure that it's a good fit. My TV is a flat screen but has a round pedestal base that it sits on which fits great on this base.
I wanted to be able to rotate my 50&#34; LG television to view from anywhere in the room. This turntable turned out to be an excellent purchase. The TV rotates very smoothly and quietly with one finger and stays where I put it. The rubber pads on the base of the swivel keep the turntable solidly planted on my TV stand. The base on my TV is 22&#34; x 10&#34; and fits perfectly on the turntable.
Item works great. I felt it was a bit overpriced at $40, hence the 4 not 5 stars. But it does what I need it to do, swivels smoothly and was the exact fit for the base of the tv I was going to use it with. The curved back end allows for more swivel if TV is near a back wall. Design was well thought out. The writing on the box describing the many potential uses for this stand is hysterical. Clearly some particulars were lost in translation!
Using this for my 50&#34; LCD screen which is about 45 lbs. The base of the TV is 16&#34;x8&#34; which is a perfect fit for this swivel. Remarkably, with the swivel, you can turn this TV with an extremely light touch. (Almost too light, when some TV wires pressed against the wall, the TV &#34;bounced back&#34; a little from the resistance of the wires!
I purchased this for my son's 50" flat screen TV due to the measurements that it stated for the swivel base. I know it was described as to be used with a big back TV, but I took a chance. And I'm glad I did. The base of his flat screen fit just inside the width of the swivel base. The swivel base is sturdy for his TV and not wobbly in any way. It was a gift he was thankful to get.
I have placed my 60" Sharp Aquos TV on this stand and it works perfectly. Just be sure to get the weight of the tv directly centered on the stand and it works just as it should. Turns easily and smoothly with one finger but never moves on it's own. I almost paid much more for a different stand because sometimes you convince yourself that more expensive must be better. I am glad I went with this inexpensive solution.
Just as advertised. this is a large and sturdy turntable with true one finger touch swivel. We use it to hold our 55 inch flat screen to make the back more accessible where we store our cable modem, etc. Our large TV base fits perfectly and is very solid with no fear of tipping.
We use it for a 52&#34; LCD TV. Checked the weight limit prior to make sure that it's OK.  Now we can swivel the TV anytime with ease.
Bought this for use with a 42&#34; Sony Bravia and it works like a charm. It allows me to swivel the TV to address different seating arrangements in the room and has just enough resistance to keep it from moving on its own.That said, it would be nice if there were a lock mechanism to make sure it didn't shift.
This is an excellent swivel tv stand especially for the older flat panel tv's that are heavier than the new ones. I have an older flat panel 46&#34; Sony XBR that weighs a ton. The stand swivels easily and rotates to a large degree since the back corners are rounded so that the tv stand does not make contact with the wall. My tv base fits on top perfectly with an inch to spare on each side.
Answer: Ours overlaps about 4" on each side and its fine.
