Hadn't thought of that. Shall weigh the costs.
Another question on this matter.
I found online that Melamine-faced board ¾-inch (18mm) thick needs 24-inch (60cm) distance between supports.
However, it doesn't mention the depth of the shelf. I would have thought that makes a difference.
For instance, for the yoga mat shelves, they would be 70cm deep and 80cm wide holding an estimate of 15 kg of yoga mats. I'm thinking that should be ok as they will probably only have the mats on them 14 hours a day.
What do you guys think ?
