You can adjust the height to a certain degree. With my 55" TV, however, there is still at least 15cm distance from the bottom edge to the floor.
I estimate that at maximum height it would be about 30 cm.
hi, the feet would be very close to each other (vesa hole spacing). the tv would be a little unstable sideways. you could solve this with crossbars with holes from the hardware store ;)
The stand is compatible with the following mounting dimensions:
With VESA 200x200, 300x300, 400x200, 400x400, 600x400 and 35kg.
Your TV requires VESA 400x400 and has a weight of 22kg. So it fits.

You can vary the height. My 55" still has about 6cm from the floor at maximum height. However, I think that a 32" is adjustable from approx. 2cm - 10cm.
The stand can be used universally up to 70" and the scope of delivery includes lots of screws and nuts in various sizes for attaching the TV to the construction. So it should work.
