What makes Weekender’s pillow so unique is its ventilated exterior. It’s made from a piece of memory foam that has tiny holes all over its surface, which helps moderate airflow so it doesn’t trap heat when your head is resting on it. It’s slightly firmer than a down or down alternative pillow, but shoppers say it’s perfectly comfortable: “It’s never felt like the rock hard memory foam that you get in cheap pillows. It’s not just a saggy mess either. It’s just right.” It doesn’t decrease in comfort over time, either. Another reviewer said that, after a year of use, it feels just as good as it did fresh out of the packaging. The pillow comes with a washable cover that doesn’t interfere with its cooling effect. “I’ve had the pillow for two months and I’ve enjoyed fantastic, comfortable, restful nights (and more than a few wonderful day-time naps),” one customer wrote. “The pillow keeps my head cool and cradles my head and neck with exactly the right amount of cushion.” Even self-proclaimed skeptics have found that the memory foam pillow helps them fall asleep—and stay asleep. To buy: $21 (was $30); amazon.com Weekender’s memory foam pillow is already budget-friendly at its normal price of $30, but its Prime Day sale is pretty hard to beat. If you’ve been thinking about replacing your pillows, now is the time to take advantage of a deal that won’t last for long.
