[HNW] Is this a good sit on frame

[Velvet Claw]

Hi everyone,

For when I do my big project

http://elmsleyrose.blogspot.com/2008/03/embroidery-sampler-project-first.html

I think that I will need a sit on frame. I have limited space - the 
couch, a bit of space to just wide enough to stand up and walk through, 
and then the coffee table - so I think a standing or lap frame will 
literally trap me on the couch unless I crawled to the other end - or if 
I leave the frame loose enough to 'swing away' every time I want to get 
up, I'm going to have to loosen and re-tighten that particular screw 
every single time I do get up, aren't I?

I also need a supported frame because I have fibromyalgia, and there is 
no way on God's Green Earth that I'll be able to hold something as big 
as a frame in my hands

What do you think of

(I think the description is a bit clearer here)

This is an Australian product, and I am in Australia - much cheaper on 
the shipping. But I want to get a good frame that will stand by me - and 
this seems quite inexpensive.

 From the picture and description, do you think it's ok?

best,
