Helix Sleep is counting down the remainder of 2022 with a rare percent-off discount. From now until January 1, 2023, code FLASH15 cuts 15% off all mattresses at Helix Sleep. You'll also get two of the brand’s best pillows bundled with purchase (up to a $150 value).

This is a departure from typical Helix mattress sales, which consisting of tiered dollar-off coupons between $100 and $350 off. Here, you'll be getting a flat percent-off discount, which in many cases will yield larger savings than the usual evergreen offer. There's also a note on the site informing us that prices will be rising on 1 Jan. This isn't unusual, as we've seen plenty of mattress MSRPs going up over 2022, but if you're interested in the Helix, now's definitely the time to buy. The current Helix sale prices are among the lowest we've seen from them all year.

That includes the best mattress for side sleepers, the Helix Midnight mattress. It's usually discounted by $150 to $200 off. After 15% off, a queen drops to $1,062 ($187 off; was $1,249). Meanwhile, you can get a king for $1,317 ($232 off; was $1,549). Read our Helix Midnight mattress review to learn more about its superb pressure relief for side sleeping.
