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.

3 layers of construction:

  • 1.5" Viscoelastic Memory Foam Top Layer
  • 1.5" Transition Layer made from a Proprietary Blend of Premium Foam
  • 7" High-Density Polyurethane Foam Core Support Layer.

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 ideal temperature for sleeping is 69 degrees. Lull's 1.5" viscoelastic memory foam top layer is injected with a gel polymer, specifically designed to transfer heat away from your body when it is warm by dispersing your body heat throughout the mattress. Breathable top-tick fibers and open cell foam structure promote enhanced airflow to help heat flow freely away from you.

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.

The Lull Mattress supports and cradles your body to provide healthy spine alignment while you sleep. 1.5" transition layer made from a proprietary blend of premium foam combined with our 7" high-density polyurethane core support layer ensures the proper body alignment while you are sleeping. A healthy spine position allows your muscles to rest throughout the night and wake up refreshed in the morning.

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.

A common complaint about memory foam mattresses is that you sink and get stuck. Not with Lull. Our proprietary blend of premium foam was designed with just the right amount of bounce-back in mind. The 1.5" transition layer responds and supports your body so you don't get that sinking feeling or a trampoline-like experience.

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.

Lull's 1.5" top layer memory foam evenly distributes weight and contours to your body's curves, which provides relief for pressure points - joints, lower back & neck. Memory foam and specialty foams ensure the proper lumbar and neck support.

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.

Lull's cover is made of ultra-premium fabrics. Our cover surface is made from polyester and rayon to provide comfort, stretch and flexibility. It is incredibly soft, breathable and durable. It is hand-crafted and easily removable for spot cleaning.
