The luxury sleep brand is getting a head start on summer, with a can’t-miss Memorial Day sale that’s arrived a week early. For a limited time, you can get up to $800 off a mattress and base combo, plus up to 20% off other sleep accessories — bedding, pillows, and more. We know a good night’s sleep is necessary for coping with stress, resting tired muscles, and supporting your immune system. We also know that far too many of us don’t get enough sleep, with young women especially less likely to get the Zzzs they need: According to research from Gallup, only 27% of women aged 18 to 49 report feeling rested. Yikes.
