Furniture
Furniture is the moving-day category: you only learn these weights the hard way, once every few years, with your back. Solid wood versus flat-pack chipboard versus hollow frames — the same silhouette can differ by a factor of three.
Mattresses and sofas are the classic traps: huge volume, surprisingly moderate weight. Pianos are the opposite kind of trap.

Furniture: frequently asked questions
How heavy is a three-seat sofa?
About 90 kg (200 lb) — the weight of two queen mattresses. That's why moving one is strictly a two-person job.
How much does a mattress weigh?
An average queen mattress weighs about 45 kg (100 lb). It feels heavier than it is because it's floppy and impossible to grip — awkwardness, not mass, is what breaks backs on moving day.
What is the heaviest piece of furniture in a normal home?
If you own a piano, that: an upright weighs about 220 kg, and a slate pool table over 300 kg. In piano-free homes, a massage chair (95 kg) or a big wardrobe (70 kg) usually wins.
What are the lightest and heaviest furniture objects in the game?
The lightest is Bean bag chair at 4 kg (8.8 lb), the heaviest is Slate pool table at 320 kg (705 lb).
