Adjustable Tension Pole Shelving, 4-Tier, No Drill

Why this one

Four tiers that stretch from 15.4 to 27.2 inches across and from 4 to 10 feet tall, held up by spring pressure alone. No load figure is published anywhere on the listing, which is normal for this type and worth knowing before you put a stack of books on the top shelf. In a bedroom it works as corner storage or beside a tall bed frame, and it gives you more shelf per square inch of floor than anything else here.

What it had to clear

• poles that brace floor to ceiling, so nothing is fixed to the plaster at all
• a width that suits a bedroom wall rather than the gap above a toilet
• shelves that stay level once loaded, which is the known weak point of this type
