Turning 60, I have yet to learn appreciation for this product niche. A decent foam-rubber thingy costs me next to nothing, can be rolled up and put in the car boot, and will last me several years, call it four or five.

I bought a cotton-filled Japanese futon mattress and slept on it for 6 months. In the end, I was still waking up with hurt joints, almost like bruising, and I bought a $1,000 mattress instead.
So I think it's due to individual nerve differences or something...
Mattresses are oversized sanitary napkins but people keep them around far longer than they should because they pay so much for them.
I appreciate the plusher mattresses hotels have, but at no point have I thought to spend anything close to what these mattress places usually charge.
