Now THAT is a loaded question!
The answer should be simple, right?
Well, how much does it cost to BUILD a box spring (aka foundation) at the factory?
(The answer is about fifty bucks: $50.)
We just pass through that same price of $50. No markup. No margin. No profit. We absorb the cost to pickup & store the foundations.
Why? Well, because the rest of the industry seems determined to double the cost of everything. They multiply cost by 2-point-something. That is their magic formula. COST times 2.4x or 2.6x seems to be the acceptable market margin. On a box spring!
People can sense when they are being gouged. They know it.
Here is what JUST a box spring sells for locally:

Why give it away?
Because then people relax and listen better to what our mattresses cost. They know we are not out to make a buck from every angle. All proceeds go to effective world evangelism anyway.
Some might be thinking: "But won't people just take advantage of you? I mean buy the mattress elsewhere and come get a factory-cost foundation / box from you guys?"
Well, that would be fine actually. We are confident our mattress quality and price point is worthy of comparing.
