Hello Everyone: I know this topic was beat to death before, however, since it's been a while I thought I would start a new Thread about the large space of the Prius and the ability to sleep or nap in the back. Here's what I did. 1. Removed headrests. 2. Dremeled off those baby hooks, and purchased a foam bed topper from Bed Bath & Beyond. Today, I cut the foam out and so it fits in the back. However the underside is still hard, so I might buy another Topper. Suggestions? Or a waste of time? Thx.
