Needed to buy a new bed and it had to be king size. IKEA is only a few miles but the mattress is huge and can't be folded. For non US readrers, the size of a king mattress is aprox 197 cm x 206 cm The boxes fit easily in the Model S but the mattress had to go on top. I rolled down the windows to fit two straps through to tie the mattress down. Once I was done I realized that with the straps in place I couldn't open to doors any more. After contemplating and staring for a moment I remembered that the doors don't have a frame around the glass and I could just open to doors! LOL duh!! Love this car! What I find very interesting about these photos is it shows how massive the car really is. The mattress doesn't look so large any more sitting on the car.
