What to know before buying

Capacity claims are conditional: the listing states 175kg per tier and 875kg total, but advises against fully loading all five tiers to maximum, especially the top two. Customer feedback also describes freestanding units as flimsy. Treat the stated loads as listing claims, not verified performance.
