We went into andersons and stood on all their samples. And that's how we choose ours. We picked one that was cheaper than others that felt less nice. We didn't buy the absolute cheapest available but we weren't far off. It was on sale at the time. We also went for a better quality underlay as KittyK said, it made a real difference to the feel. The store had samples of different types so we were able to try them all out. We didn't have kids at the time so we had plenty of time to try them out without stopping toddlers from destroying the shop though.
