Burundi Geography. The landlocked small country of Burundi, located on the northeastern shoreline of Lake Tanganyika, is a very mountainous country. The only land below 3,000 feet is a narrow strip of plain along the Ruzizi River in the west. Burundi's highest point is Mount Heha which rises 8,759 ft.
Re: car seat cushion foam replacement. I bought seat foam from BCS about eight years ago and it was too stiff. I bought a narrow can from the grocery store and after cleaning it, I used a hack saw to cut the top lip off. This makes a great foam cutter, no flying debris like a hole saw.
If you fix it, it'll likely happen again. The issue is that the springing under the first layer of cushion has sagged, and the leather is being stretched more than it can tolerate. To really fix this, you'll have to get into the seat bottom construction itself. That can be a big undertaking, or not. But you need to see someone expert in this. Any DIY fixes are guaranteed to fail. When restoring the seats for my '62 Porsche Cabriolet, Guy Recordon at Guy's Interior Restorations actually sewed the seat covers from a whole hide.
