Getting up to bed with a stool dies nit work anymore Hopefull this work.
made a step , 30mm thk recycle rimu timber with a routed grove to the underside to sit on existing half panels board under the bed.
Then made a pair of HW timber keys that slots to the side channels.
Now, there's a plan! Proud owners of our GC600 since June, the one unresolved challenge so far, is getting into/on to the bed. Use a stool, lavatory door won't open ......... Anyone else got a solution?
