Spin in the Spring, Flip in the Fall
All you ever wanted to know about keeping your mattress in the best shape -- literally speaking. It's all mathematics.
Now for the payoff. The diagram shows how to get the most even wear out of a mattress. Any strategy that samples all four states periodically will work. For example, alternating R and H is convenient — and since it bypasses V, it’s not too strenuous. To help you remember it, some manufacturers suggest the mnemonic “spin in the spring, flip in the fall.”Of course, if you have one of the new "improved" one-sided mattresses the solution is considerable easier, although your mattress will last only half as long.
Speaking of one-sided mattresses, I've always wanted to use this since I heard it last year:
TERRY GROSS: I thought great, no-flip mattresses, you don't have to go through the work of flipping it, and the bed's kind of extra-good, so you don't have to flip it, but there's another reason why you don't have to flip it.And it certainly makes the mathematics of mattress flipping a lot less interesting.
(Soundbite of laughter)
Mr. KOSMAN: That's right. Initially, they made the mattresses thick. They kept putting - creating thicker and thicker mattresses so they had an excuse to keep raising and raising the prices. So they thought, both Sealy and Simmons both had the same thought. The private equity firms that owned them both thought, well, why don't we cut costs significantly and cut the beds in half and introduce these no-flip mattresses.
Simmons did it first, early this decade. Sealy stood back. Sealy even made a statement when Simmons did it, saying we would never offer a no-flip mattress. That's why you should buy our mattresses. Simmons's sales didn't rise, but their earnings went through the roof. The private equity firm that owned Sealy at the time, which was Bain Capital - the same firm that Mitt Romney owned during that period, the Republican presidential candidate - decided okay, well, we'll change tack. You know, even though our market share is growing, their earnings are going through the roof, and that's what we care about. So then they introduced no-flip mattresses, and now and for the last six or seven years, Sealy and Simmons only offer no-flip. There are no two-sided beds anymore.
GROSS: But are their no-flips any better or worse than the two-sided ones?
Mr. KOSMAN: Well, they certainly have less of a life. You can't flip them, so just like a tire, you know, when you rotate your tire, you know, beds that used to last 15, 20 years on average - and those were Sealy and Simmons beds - now these beds last six, seven years. So it's a much cheaper bed. And what ended up happening in the middle of this decade is Tempur-Pedic came out of nowhere. And Tempur-Pedic offered a very nice sleep on a - I guess they call it, you know, it's those foam beds, and those mattresses, on the high end, which is all that Sealy and Simmons at this point were now competing in, they started to really outsell Sealy and Simmons. And that puts - and then Sealy - for Sealy and Simmons, not only were they losing market share, now their earnings were starting to fall.
