Mattress Construction

Materials Overview

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.

With the iComfort by Serta® mattress, cool, supportive sleep is the priority. The base model (CF1000) has these layers:

  • Carbon Fiber Memory Foam
  • EverCool® Fuze Gel Foam.
Three upgrades are available at additional cost.

Comfort Info

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.

Specifically designed mattress to keep even the warmest of sleepers cool. You don't have to be a hot sleeper to love iComfort. You just have to like your sleep environment to be refreshingly comfy. Three cooling upgrades available:

  • Cooling Upgrade (CF2000): 11.5" Additional cooling and firmer support.
  • Max Cooling Upgrade (CF3000): 12.5" Cooler and more breathable.
  • Max Cooling & Pressure Relief Upgrade (CF4000): 13.5" Feels and sleeps cooler, with air support layer to take pressure off joints.

Support Info

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.

Multi-layered foam technology adds support, resilience, and temperature regulation for the coolest, most comfortable sleep ever.

Comfort Specs

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.

Every iComfort mattress is made with our exclusive Carbon Fiber Memory Foam. This system channels heat away from your body.
Gel Active® Max Foam (used only in CF2000 model) is an open celled memory foam helps promote airflow, so you don't have that hot, stuffy feeling when falling asleep.
UltraCold System™ (used in the CF3000 and CF4000 models) The layer of extra-cool Carbon Fiber Memory Foam is engineered to work hard at absorbing excess heat from your body, then channel it away, all while you sleep comfortably.

Support Specs

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.

Carbon Fiber Memory Foam provides exceptional strength for back and neck support.
Air Support™ Foam (used only in CF4000 model) moves with your body and contours around it to help alleviate aches and pains caused by pressure points.

Fabric Specs

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.

A Max Cold™ Cover is used in the CF3000 and CF4000 models. Made from super cool high-performance fibers for an instant cool-to-the-touch sensation.
