I had my sister go in and have a look at the bed at Furniture City. She reckoned that the sales guy cringed a little about the bed. He said it was quite difficult to put together. My sister felt that it looked quite cheap in real life too.
The guy at Furniture City showed her a Captains Trundler Bed which wasn't on the website, similar to the Harvey Norman one but only 498, mattresses extra. It was great quality, came in white and brown stain, had bigger storage drawers and they were on rollers. The guy also reckoned it was easier to put together.
Hope that helps! It is hard when you can't see things in person.
