Hi,
I've got one of these as well, for the same reasons as your good self - gotta be stored away.
In that regard, it is very good indeed. It folds up simply, and you've got two velcro straps to hold it securely, top and bottom.
The one area I would moan about is the height of the steering wheel platform is non-adjustable. I've got a Fanatec GT3RS screwed on it, and with my delicate frame enclosed in the seat, the wheel is far too high up.
To get round this, the placement of a cushion under the posterior works wonders. Depending on your size, you might also want one behind your back as well.
Not trying to put you off, quite the reverse, and if you're over 6 foot, this probably won't be relevant, but might be of use to other types who are looking.
Other than the above mentioned gripe (which is fully fixed with aforementioned cushion), it's a really good addition to the whole experience.
Good luck... 👍
