The Mainstays Back & Side Sleeper Pillow is an extra-firm bed pillow sold as a four-pack in Standard/Queen size. A gusseted sidewall adds loft for back and side sleepers, and the polyester microfiber fill is hypoallergenic with antimicrobial protection against odor-causing bacteria. The 100% polyester peachy microfiber cover feels soft and cleans easily. It suits people who want a firm, high-loft pillow for the whole bed rather than one premium pillow, and it competes on value against single-pillow brands that cost more per pillow.

Owners rate the set well overall, with most praising the firm support and the value of getting four pillows. Complaints center on firmness being too much for some sleepers and on pillows losing loft after months of use.
This set includes four extra-firm Mainstays pillows in Standard/Queen size. They are made for back and side sleepers who prefer a firmer feel.
Each pillow has a gusseted design along the sides. This adds loft for back and side sleeping positions and gives the pillow a fuller shape.
The fill is polyester microfiber, and the cover is 100% polyester peachy microfiber. The fill is hypoallergenic. Antimicrobial protection helps resist odor-causing bacteria between washes.
