Pillows: They come in any color as long as the color you need is GRAY.

Pillows are a hard thing to build; if you want them to last, they must be hard. If you want them to be soft (who doesn't?) then they will be easy to corrode. This is the most common complaint: Why did they fail so soon?

It really is a problem. Just remember that pillows cannot handle soaking in water or toxic gas. Of course, that is funny because they are in a moist environment that is loaded with gas. Because of that, if you want to maximize you pillow's life, make sure they remain dry as possible and that your water chemistry is balanced and you don't use a lot of chemicals.

Easy to Say. But I have seen customers put the water line above the bottom of the pillow and wonder why the pillows soaking in water failed. Others don't maintain the water chemistry and also get a blistering pillow. But if you know going it those factors are important and the cost of replacement of pillows, then you will keep an eye on both.

Also cleaning the pillow with protectorant has been known to help to reduce chemical damage to the pillows.
