We got a bunk for Matilda & Jovie from SuperAmart, i was sceptical about the price... but it was super sturdy in the shop & the sides were taller than the average bunk so we bought it & with 2 mattresses it was $1000 all up, so I can understand, but that was because I got super high tech mattresses. If I had gotten the foam one they recommended it would have been $600 all up.
