Millard Full Trifold Mattress On Sale On Amazon

I have been looking at trifold mattresses for my 2013 prius for a while for my wife and I to car camp at the beach this spring. From the reviews I had read I knew I was going to buy a Milliard brand but wasnt sure if I wanted 4" or 6" though. Well pulled the trigger this morning since Amazon has the Milliard premium trifold 4" full mattress for $105 with free ship right now. From what im reading the difference in the premium and regular milliard trifold is the premium has a removable waterproof cover while the regular does not and possibly more memory foam as well? it shows the mattress can be flipped with one side softer and one firmer side. I also purchased the carrying case which I believe was $24 to keep it clean and transportable when not in use. Link is from my affiliate amazon page but i have no affiliation to Milliard. Hopefully it will help someone out there looking for a two person mattress for their prius or prius V as this is by far the cheapest I've seen for these. Not sure if they have any deals on the single person size but the full is supposed to be a perfect fit for the back of a prius.

Bill there are some people who like to use their prius to car camp, its a good part of the reason we bought our V.

 

That is my next step, but yes you have to build a support up at the head of the mattress that will hold up where the rear seats folded down end and the back of the front seats begin. There are a few ways of doing this I've seen online but that will be an upcoming weekend project.
