FAQ
Questions, answered straight
Do soft boxes feel unstable at 30 in?
A well-strapped stack or a dense 3-in-1 feels planted for controlled landings, with a small compression give that wood does not have. The instability stories come from unstrapped stacks and budget foam at heavy bodyweights. Follow the strap discipline and size the foam density to the athlete.
Can soft boxes be used outdoors?
For sessions, yes; vinyl covers wipe clean and foam ignores a little weather. Store them dry and out of permanent sun, which ages covers and foam alike. A wooden box left outside degrades faster than a foam one stored with basic sense.
Are soft boxes good for box squats and step-ups?
Light, controlled step-ups yes. Loaded box squats and heavy dumbbell step work belong on wood or steel: sustained load compresses foam unevenly and changes the target height mid-set. Match the tool to the load type, not just the load number.
