The Plank Firm is Brooklyn Bedding's 10 in flippable all-foam mattress with a firm quilted surface on one side and an extra-firm surface on the other - the firmest feel in the Plank line. SleepCity carries it in Twin only, without the GlacioTex cooling cover, making it a budget-friendly ultra-firm option for guest rooms, dorms, bunk beds, and back or stomach sleepers.

  • Flip the two-sided design between firm and extra-firm quilted surfaces to dial in your preferred firmness level.
  • A 6-inch high-density foam core keeps the spine level, giving back and stomach sleepers plank-like support.
  • CertiPUR-US certified foams and GREENGUARD Gold certification back this simple, durable all-foam twin build.
