Firmness Info

A firmer and supportive feel.

The Kiwi mattress is a firm yet contouring hybrid mattress. Ideal for growing children, or adults looking for an affordable option. The two-sided option repeats the layers on both sides of the springs, both sides having the same feel and firmness. This option extends the life of your mattress but is currently only available by contacting their customer service team.

Mattress Construction

Materials Overview

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.

The Kiwi mattress is a safe, healthy and affordable hybrid latex option, with a 2 layer construction:

  • GOTS-Certified Organic Cotton quilted cover
  • 1" GOTS-Certified Organic wool batting
  • 2" GOLS-Certified Dunlop latex (Density: 65, ILD: 22-24)
  • 8" Zoned Pocketed Coil Spring Designed & Manufactured by My Green Mattress, Inc.
For a small additional cost a two-sided (flippable) mattress is available which has the latex and wool layers on both sides.

Comfort Info

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.

The GOTS-certified organic wool batting is sourced from sheep that are allowed to graze freely in organic pastures. The wool acts as the only flame retardant, and is hypoallergenic, temperature regulating, and 100% biodegradable.

Support Info

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.

Tighter coils along the edges of the mattress provide a firmer seating edge. With proper support across the entire mattress you can sleep from edge to edge and top to bottom. Steel springs will last up to 4 times longer than a foam support edge.

Comfort Specs

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.

The breathable and hypoallergenic latex provides a naturally cool sleep that is dust-mite, mold, and mildew resistant.

Support Specs

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.

Individual 13 3/4 gauge coils react to body shape and weight to keep pressure off your bones and joints. Each fabric-encased coil moves independently to allow deep sleep even when your partner
Latex is supportive and alleviates pressure points that can cause stiffness, pain, tossing and turning.

Fabric Specs

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.

Wrapped in 100% GOTS-certified organic cotton fabric. This soft, durable cotton is a healthy alternative to synthetic fabrics and is free from polyester fibers and pesticides.
