Just received my Voltra and want to build a portable platform for squats and other exercises. Something similar to Voltra's Travel Platform or Eve's Helios/Mount Olympus. I would buy one of the existing products, but there's no easy way to get them delivered to my country.

Saw lots of different options in this community and was wondering what's the best design to go with. I will use it with 1 Voltra and ideally want to attach a 2:1 pulley. So basically I have 3 questions:

1. Material: steel or wood? I guess steel can handle more load, but does it really make a difference for this platform?
2. Size. Travel platform is 27x15. Is it enough? Or make it bigger?
3. Pulley. Would you use platform's handle to attach a pulley or add a special anchor for it?

Any advice would be appreciated! Thanks!
