Another creator did a build and review of this she said there are updated building instructions that include the strap install on the website. Hope that helps 😃
I like it, too. I like its relaxed look, as if it is all about being comfortable and making your guests comfortable. You can straighten it up if it starts to look "too relaxed", and you can wash both cover and cushions in a washing machine! It looks like a decision well made to me.
Just keep in mind that if you go to this or any other Princess Meal with at least 1 Little Girl, be sure that the Girl wears a Princess Dress so that the Princesses can see the Dress.
