Have you varnished them?
Just put ours up,fab for the money but didn't realise they weren't varnished like the Trofast range which the dtwins have in their bedroom.
As they are solid untreated pine they look very ermm clean and light (stand out like a sore thumb in their bedroom). Do they darken with age and is it ok just to leave them as they are?
Still can't get over what a bargain they are
