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.
Two layer construction:
  • Bio-Pur® foam
  • Bio-Core® foam support layer
  • Refresh Cooling Cover.
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.
Our foam is also better than traditional memory foam because it recovers its shape faster. With a typical foam mattress, you often wind up "stuck" when you change positions but the mattress is still holding your previous shape. That's because it takes around 60 seconds for the foam to bounce back.
Ours bounces back in just four seconds, so as you move at night your mattress keeps up with you, providing superior comfort.
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.
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.
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.
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.
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.
Bio-Pur® breathes and conforms to your body. When you lie down, you'll feel Bio-Pur® relieve your 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.
Refresh Cooling Cover
The Refresh Cover draws heat from your skin for a delightfully cool-to-the-touch feel. On average, your sleeping surface will stay 7 degrees cooler over an eight-hour night of rest compared to a traditional 100% polyester cover. This scientifically engineered fabric uses minerals to help convert your natural body heat into far infrared energy. This type of energy increases blood circulation to help speed up muscle recovery and improve quality of sleep.
