Folding headrests?

Does anyone know if there are folding headrests that will fit in the back seat of a double cab? I just upgraded my 94 pu to an 05 tacoma, and the headrests in the rear seat make HUGE blindspots, so I'd like to replace them with either folding headrests or smaller ones (like the one in the middle of the back seat).

It's worth noting that I adjust my side mirrors differently than most. If you adjust them further out there is no blind spot and you never need to head check. If a car is far behind you, you can see it fully in your rearview. If it's a car length or so behind you, you can see it simultaneously in your rearview and your side mirror. And when its right along side you, you can see it in your side view and also out the front two windows without turning your head. I've always thought it odd that so few people do this. It's very convenient and safe. Anyway, I digress. I'm looking for rear seat headrests that block less of the rear view. It's also harder to see the corners of the bed when backing into tight spots. Any ideas?
