Foam mattresses

Re: To sleep, perchance on foam

Despite recent assertions in C&EN (July 17, page 20), the polyurethane mattress industry has not made nearly enough progress toward providing an acceptable product to the public. The temperature profile of foam mattresses is critically important not only to whether the mattress feels hot but also to muscle-skeletal support. Based on my experience, these mattresses become rubbery, sink, and lose shape under simple body heat. This leads to spine and muscle problems. For this same reason, those who want a cold room should be informed that an electric blanket cannot be used with a foam mattress. Worse still, a buyer cannot adequately assess the temperature profile of a foam mattress through a 10-minute test in a store.

As Member No. 41152 of the Sourtoe Cocktail Club, I can attest to the fact that, while the toe may be disgusting, the drink is perfectly fine as long as one chooses a decent alcoholic beverage such as a good Irish whiskey to accompany one’s becoming part of a unique tradition.
