Mattress Construction

Materials Overview Three layer construction:
  • Bio-Pur™ foam
  • Ergonomic transition foam with Surface Modification Technology (SMT)
  • Bio-Core™ foam support layer
  • Celliant® 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 Traditional memory foam is made from dense material, so it traps your body heat and can make you sweaty and uncomfortable while you're in bed - and who can sleep like that?
We developed our foam with an enhanced "open cell structure", which means there is more air space between the foam particles. That space wicks away heat while you sleep, and can keep you cooler and more comfortable.
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 Bio-Core™ foam support layer won't sag even after decades of use. And, like our Bio-Pur™ foam, it's partially made from plants instead of petroleum so it's eco-friendly. 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 The Affinity layer has precision-cut channels that carry away even more heat and moisture. It's enough to make you feel like you're weightlessly resting on a cloud.
Our Bio-Pur™ foam is five times more breathable than traditional memory foam, because of its advanced open-cell structure. It wicks away heat while you sleep and can help keep you cool and comfortable.
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 The Affinity layer with Surface Modification Technology (SMT) is our ergonomic transition foam. It has "zones" that provide extra pressure relief in key areas like the shoulders and lower back. 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 High-Performance Celliant® Cover
Amerisleep is officially licensed to use Celliant® in our covers. This advanced fabric combines 13 minerals into thermoreactive yarn that converts body heat into infrared.
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.
