There is a hidden button that you have to push. I cant remember on which side but you will be able to feel for them. I used a key to kinda push it. Basically it is on the same placement as the ones on the rear seats IIRC. I will check on the placement but it gets removed easily. Here is what I have replaced my seat covers with.
Wow, those Clazzio seat covers look amazing! Are they still available? I tried searching on Clazzio's website, Clazzio.com, and did not find any seat covers for the Toyota Previa.
Please provide more information on how you got your's.
I have removed the front seat because I will try switching the front and middle seat covers after they are washed. The middle headrests came out easily once the release is pushed, but my daughter and I have thoroughly examined the front headrests and all around their bases, but we don't find a release button anywhere. The seats look exactly like the ones in the picture you attached. We must be missing something. Is the release on the armrest, (Middle of the van) side, or on the outside? The other problem we are experiencing is that the zippers for the armrest covers are frozen in place. They aren't rusted at all, the zipper itself is nylon, but it won't move in either direction. I tried a little electric parts cleaner, but that didn't help at all. This is a 1992 Previa GL that was imported to Thailand's new, but that is the same as a 1993 in America. It belonged to a Thai who who owned an auto insurance company here, and who took very good care of it. I can tell that it had been rear ended at one time because the rear door and latch are from a newer model, and didn't work properly. When I looked for a replacement latch, nothing I found would match the door, so I had to do a little creative machining and now everything works great.
