Brooklyn Bedding Plank Firm vs Sealy Cocoon Chill

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.

The Cocoon Chill is a medium firmness, about a 6 on the firmness scale. We've found that most sleepers prefer a mattress that's fully supportive but not too firm, so we created a mattress with our Perfect Fit memory foam that adapts to your unique body size, shape and sleep position.

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 layer construction:

• Perfect Fit Memory Foam
• Personalized Comfort Layer
• Support Foam.

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.

A top layer of memory foam helps reduce the amount of movement from your sleep partner. The Soft model reduces a bit more motion transfer than the Firm model.

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

Our high-quality memory foam adapts to your body size, shape and sleep position to ensure a great sleep no matter which feel is right for you.

Phase Change Material (PCM) absorbs your body heat leaving you with a cool to the touch mattress experience.

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.

Support Foam base layer engineered to be highly durable and resilient. We've tested it, and we know it bounces back every time.

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.

Our premium stretch-knit cover is infused with a proprietary "Phase Change Material" that absorbs and dissipates heat for a refreshing, cool to the touch surface.
