Our Graduate Series™ is made of solid rubber wood (Hevea Brasiliensis). At ULoft, we plant, harvest and use the wood from a fast-growing type of hardwood rubber tree. A rubber tree? Well, yes. Among the great things about the Hevea Brasiliensis (HB) tree are that it 1) has been proven stronger than oak, 2) grows far more quickly (so it can be harvested and replanted sooner) AND 3) it produces a form of latex that can be tapped during its life cycle. And because the HB tree can yield all those student desks, fewer trees need to be harvested! This makes HB a perfect – and environmentally responsible – choice for University Loft’s strong and durable student furniture.
