'These items are more fragile, irreplaceable, and meaningful than everyday possessions' – storage experts warn that this is the one thing you should never keep in a storage unit

A traditional style living room with white walls, a gold mirror, patterned, mismatched sofas, a plaid ottoman, large windows, and open curtains.
