Our Take on the Plank Black Friday Sale
Plank is made by Brooklyn Bedding and is one of the few mattresses designed specifically for firm-bed shoppers. It is flippable, with a firm side and an extra-firm side, and it is a top pick for stomach sleepers and heavier back sleepers.
Black Friday is the best time to buy Plank because Brooklyn Bedding applies its sitewide percentage to the Plank line too. We typically see 25–30% off plus free pillows. The discount is real because Plank holds a steady list price outside of events.
Expect the sale to open in early November 2026 and run through Cyber Monday. Plank ships free and offers a 120-night trial.
Two free Plank pillows ($120 retail value) with every mattress purchase.

Should You Buy Plank This Black Friday?
Buy it if
- You want one of the firmest mattresses available online
- You sleep on your stomach or are a heavier back sleeper
- You want a flippable firm/extra-firm design
Skip it if
- You are a side sleeper or lightweight sleeper — the surface will feel too hard
- You want pressure relief or a plush top layer
Our verdict
The Plank Firm at roughly $524 for a Queen is the best Black Friday value for anyone who genuinely needs a firm surface. It is not a compromise mattress — buy it only if firm is what you want.
