Best Rectangular Backrest Pillows in 2026

Adjustable pillows are often a case of being sold something that isn’t quite as advertised. With the Coop Home Goods Original Pillow, you have full control. Pull off the cover, and inside you'll find a combination of cross-cut memory foam and microfiber (coined Oomph fill) that you can scoop out in handfuls to decrease loft or add more to increase support. Depending on how you like to sleep (stomach, back, side) you’ll want to find the right height. Having the ability to adjust is critical. You’ll also appreciate the Lulltra cover that is nice and soft and breathable. There’s an extra bag of fill that comes along with it, so you’re not doomed to your first iteration of tinkering. The foam is newly made (not recycled) and comes with CertiPUR-US and GREENGUARD Gold certifications, so you’ve got that safety thing covered as well.
