Hehe... my last bed was 20+ years old :P Then again... it was a waterbed
We spent a lot on my mattress.... Something around $1000 after tax and such for a queen. It was bought at a mattress factory type of place - where they make their mattresses on site. We were sold on their stuff mostly based on what the inside of their mattress looked like compared to their competitors (aka - the band names). They actually had other mattresses cut in half.
As for why this one was so expensive.... This thing is monstrous - it's just shy of 18 inches thick. But, it's a double sided pillow top which is great for anyone capable of flipping their mattress every 3 months. That prevents body impressions
We did save a lot on the bed though - we built it from recycled wood that a yacht was just going to throw away. And it's a platform bed - so no box spring is needed. We expect the thing to last more than 10 years (if we take care of it) - so for two people, it costs less than two pennies each per night.
Sorry for my long winded reply, but what I'm getting at is that small scale companies that you may have never heard of are nothing to be afraid of
Especially when they take the time to show you how they build their product (which I guess is only good if you already know a little on how these things are done).
