We opened up a mattress that’s been around for 40 years and honestly it’s wild seeing what’s hiding inside. Once the outer layers come off, you get a look at decades of wear, old padding, springs, dust, and materials that have been compressed from years and years of use.
It starts off looking like a normal old mattress, but the deeper they dig, the more interesting it gets. Some of the layers have completely broken down while others have somehow managed to survive all that time. It’s one of those videos that’s weirdly satisfying if you like seeing how everyday things are built and what happens to them after decades of use.
After watching, you might start wondering what your own mattress would look like on the inside. Forty years is a long time, and this teardown really shows it.
