The wooden slats that fix this to the bed base are very cheap and weak. Also the threaded inserts they screw into break free very easily. We gave up and used some brackets from screwfix (part no 11423) to wall mount it. 

Colour: for charcoal it is quite light. 

The foam used to stuff it feels like it is cheap: when you lean against it it takes a long while to recover and looks/feels a bit baggy until it does. I don’t know how we’ll this will age with time as foam usually doesn’t improve with age. 

Overall I am disappointed at the quality for the price.
