What our customers are saying about us
Big shout out to Mumble by Design. Needed a product substitution within 48 hours and Mumble made it happen. We were able to meet our handover and without going over budget.
Over the past two years most of our classrooms have been converted from the old single style desk model to 21st Century Collaborative Zones to reflect the changing nature of the modern classroom. A number of staff had expressed concern about the process of running assessment tasks within the collaborative spaces. The Screen-ED desk dividers are the perfect solution to this problem.
We have been looking for flexible, affordable dividers for some time and Mumble By Design’s Screen-ED are perfect. They enable us to transform group tables to individual learning spaces in an instant.
