I had posted previously about having an alternating-tread staircase for access to Grant's bunk beds. Willie had sent me a sample of one done by a colleague, but that was pretty expensive, even before our recent budget crunch.
A further search found a UK company who makes these stairs, and I contacted them regarding a custom set. They responded very quickly with a detailed offer, but the total cost was still £325.
Sooz thinks this is overkill and she prefers a simple £25 ladder from IKEA. We'll look more closely on our Easter trip and decide then. I'm leaning towards cheaper these days....!
