I don't know what the last 3 pics are, not what I got. The one I have has the 2 arms with a knob adjustment at the elbow like the top pic.

Each of the arcs are the same length. The photo doesn't show this accurately.

It doesn't go straight up, it looks like it's leaning, in my opinion if you put 2 side by side it will look like 2 side by side, not like one piece. I really like it tho and it's a nice size and nice quality.

There are 2 models, one for 60 and one for 70. I agree AP3's answer. But I did note some arm sagging when arms are fully extended.

I has two hinged arms that allow it to swivel to the left or right depending on which arm you extend.

I believe there are two models. The lower-priced model does not have adjustable arms; and the model with the adjustable lumbar support does.

I really don't know for sure. I did go and look at the picture from different angles and it didn't appear to change. Hope this helps

There are bolts that are connected to the middle of the three arms. And the post has holes for the bolts going up and down the back of it, look at the 4th picture.

If you pay attention to the picture detail. It shows right. There is another one that shows left.

It's supposed to flip and swivel, but it should not do so by itself. If it's turning by itself, you can tighten the thumbscrews on the sides.

They actually have different amour of clips on the pieces. Like there are extensions with 4, 3, 2, and 1 clips on the extension pieces.

Strangely enough if you look at this website on a mobile phone it shows 7 very detailed pictures that you can scroll through. One of those pictures shows it lifted and another shows a close up view of the hinges. If you view this website on an iPad or computer it only shows one.

Hello Sandy, I have this item and it swivels up/down/left/right. It's a good buy. I really like it.

You are looking at the same product! The 3 pictures are showing you what it looks like at different angles or positions....that's all!

I remember having that problem, too! It's not intuitive. The upper section of the sides/vertical arms has to be removed if I remember correctly.

it's not a swivel base per say. it does have three holes so you can have it in many angles. To be able to angle it in other positions you lift it a little and move it to the angle you want it to be and push down. it does have in one of the joints a swivel per say to angle it up or down. I did have one that had a swivel, and was a pain in the ass to use. this is so much easier and more stable, rugged and can take a lot of abuse. the one with real swivel tend to wear out much faster. I have tried several others and they all fell apart or worn out. this in my book is much better than the rest of them. just make sure you use STAINLESS STEEL (screws, nuts, and lock washers) to attach the base. it's not a swivel base per say. it does have three holes so you can have it in many angles.
