The Hammacher Schlemmer Institute's tests reveal the one Gel-Infused Cooling Pillow that can irrefutably be called The Best. The Institute forwards its recommendation to Hammacher Schlemmer's buyers so they can procure the product for its catalog, web site, and retail store. The Gel-Infused Cooling Pillow that is currently The Best can be found here.
Before undertaking testing, The Hammacher Schlemmer Institute surveys panelists to learn which attributes are most critical when purchasing a Gel-Infused Cooling Pillow. Cooling Effectiveness was indicated as the most important concern, followed by comfort and durability. These attribute rankings are applied to the data collected for this test.
To be eligible for testing, units must be of standard size, made from memory foam, and infused with gel.
The Hammacher Schlemmer Institute then researches the marketplace and obtains Gel-Infused Cooling Pillows that possess these desired attributes and features. The Institute may eliminate a model from consideration prior to testing if it does not have a required attribute or feature or if it has an obvious quality issue. Conversely, if a sample offers a unique benefit that distinguishes it from other models, The Institute may at its discretion include it in testing even though it may be lacking a critical feature or attribute.
Testing involves evaluations by a textiles laboratory and panelists. Each pillow is rated for its cooling effectiveness, comfort, and durability.
Laboratory analysts tested each model for eight hours using a heated mannequin, calculating each pillow's average temperature from measurements taken at the first 30 minutes of the test and at the last 30 minutes of the test. Analysts also calculated the percent rise in temperature for each model. Each model was rated on its average temperature and the percent raise in temperature, each attribute being scored 1 to 10, with 10 indicating the lowest average temperature and lowest percent temperature rise. Scores are averaged and weighted and each model receives a ranking for Cooling Effectiveness that affects its overall score.
Panelists rank each model's comfort with a score of 1 to 10 with 10 indicating the most comfortable. Each model receives a ranking for Comfort that affects its overall score.
Laboratory analysts placed two 5-lb. weights on each pillow for two hours, then removed the weights and measured the elapsed time it took each pillow to return to its original shape. Each model was rated on how long it took to return to its original shape on scale of 1 to 10, with 10 indicating the least amount of elapsed time. Each model receives a ranking for Durability that affects its overall score.
The Hammacher Schlemmer Institute recommends that you consider these features when shopping to ensure you will be completely satisfied with its performance:
Made from gel-infused memory foam, cooling pillows minimize temperature rises from being in contact with a sleeper's head by absorbing and dissipating body heat, providing the same cushioning benefits of memory foam. Different than pillows that use water bladders and require pre-cooling in a freezer, gel-infused pillows use an advanced memory foam design-rigid cell structure that creates more airflow-resulting in less heat build-up. Better models have built-in ventilation as well as two-sided gel overlay construction to better ensure a more comfortable rest.
The Hammacher Schlemmer Institute was founded in 1983 as an independent, not-for-profit corporation to provide independent testing and consulting services for Hammacher Schlemmer.
Although funded by Hammacher Schlemmer, the Institute functions independently of Hammacher Schlemmer. The Institute consults Hammacher Schlemmer and fulfills its mission statement without regard to product prices, brand names, margins, or other commercial considerations. Decisions on specific products to test, the types of test to perform and how to interpret the results lie exclusively with the Institute's research staff. In addition, the Institute's status as a separate entity from Hammacher Schlemmer prevents access to sensitive information, such as inventory levels or product cost, which might influence testing decisions. The Institute's independence assures products are researched, evaluated, and rated objectively without commercial bias.
