Me.
We bought new sofas so hired a scissor lift to get the old ones out and new ones in. No problems there at all.
Council weren't able to collect old ones until 14th Jan, so after some measuring I realised they'd fit into the back of our car. I took the single seater to the tip first, came home and popped the first two seater in the car and took that down. No-one there to help so I lifted it above my head and carried it the 15m to the skip. Threw it in, then thought 'Ow!'. Hurt my back between shoulder blades and neck.
Went home for the last one and when I got to the tip there was someone to help. Bloody heavy with two so not sure what I was thinking of lifting it on my own.
Stupid is as stupid does.
