BedInABox Tranquillium vs Brooklyn Bedding Plank Firm

A firmer and supportive feel.

Our dual comfort design offers two variations: the top side of the mattress is firm; the bottom side is ultra-firm, allowing for an easily flippable, highly customizable sleep.

A 3-layer construction:

• 3" 3lb Density CoolRest® Memory Foam Infused with Liquid Gel
• 2" Pluralux Foam
• 7" 2lb Density Sure Align Support Foam
• Smooth Knit Cover.

Inspired by the minimalist approach to sleep in the Far East, the Plank is the firmest, flattest, healthiest way to sleep. It has 4 layers of construction:

1. Optional: GlacioTex™ Cooling Cover (Extra Firm Side)
2. .75” Quilted Top
3. 6” High-Density Base Foam
4. 2” Supreme Response Comfort Foam
5. .75” Quilted Bottom
6. Optional: GlacioTex™ Cooling Cover (Firm Side)

3 lb density memory foam rebounds (takes it shape) quicker making it easier to change positions.
The TENCEL® cover is a performance fabric like no other, absorbing moisture completely and naturally, creating a cooler and more comfortable sleep. With more breathability than cotton, and a softer hand than silk, TENCEL® can be found anywhere from athletic wear to luxurious bedding. Nothing is dreamier than going to sleep on a bed made with TENCEL® fibers.

Engineered to reduce pressure on your circulatory system the Plank provides for better blood flow - and better lower back support, compelling you to inhale more oxygen while you snooze.

Our CoolRest™ gel advanced memory foam quickly conforms to your body for pressure relief and support without letting you sink too far into the mattress.

The Plank offers a firmer, flatter, flippable surface for a neutral spine position that's better for your back and posture overall.

Open cell memory foam increases air flow, contributing to a cooler sleep.
Sure Align foam works in tandem with CoolRest® Gel memory foam and provides perfect support for long lasting comfort.

CoolRest® Gel memory foam perfectly contours to your body providing improved pressure relief to reduce tossing & turning.
Sure Align foam designed to support & correctly align your spine so you can sleep better.

A 2" layer of our firmest transitional TitanFlex™ foam adds deep compression support.
A 7" high density base foam ensures durability and stability for the life of your bed.

The TENCEL® cover offers unique moisture management properties - absorbs 50% more moisture than cotton, making it a highly effective performance fabric. Rapid absorption of moisture proves most effective in inhibiting bacterial growth naturally, without adding any chemicals.

The flippable design of the Plank allows you to choose your ideal firmness level: a .75" quilted top layer, patterned with continuous stitching, ensures zero loft for an ultra-firm sleep experience - or, flip the mattress, and a 1.5" quilted layer, patterned with tack-and-jump stitching, creates minimal loft for a firm sleep experience.
