Firmness Info

Everyone has their ideal comfort level. That's why we've designed this comfort selector tool so that you know exactly what you're jumping into. Select from 3 firmness levels:

  • Soft, a 3/10 on the firmness scale, a light, gentle and flexible feel that conforms to your body.
  • Medium, a 5/10 on the firmness scale, the best of both worlds for an exceptionally comfy feel.
  • Firm, an 8/10 on the firmness scale, solid and stable support throughout your sleeping surface.

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.

The Transformation Mattress by Diamond Mattress is constructed of:

  • 2" CoolTouch Advanced Regulating Fabric
  • 2" Diamond Hyper Conductive Sparkle Foam
  • Mirco Coil Comfort Layer
  • 2" HD Comfort Layers
  • Patented Zoned Support System - Foam Encased.

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.

Foam Encased Comfort Edge: Increases usable sleep surface by allowing you to sleep all the way to the edge without feeling like falling off. Creates a better edge for entering, exiting and sitting on the side of the mattress.

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.

Combination Foam and Coils: Superior Pressure Relief. Contours to your natural shape to help achieve a comfortable sleeping posture. Hyper conductive foam regulates core temperatures for a natural sleep. Coils provide breathability and additional comfort and support.

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.

Diamond Sparkle Foam actively regulates your core temperature for the most natural sleeping environment. Graphene and conductive flakes dissipate heat from the surface of the skin.
Wrapped coil design enhances airflow and breathability to keep you sleep environment more 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.

Patented Zoned Support System: Adding 25% more support where you need it most

  1. Additional Wrapped coils in the center 3rd provided extra back support where you need it.
  2. Improves alignment by relieving pressure along the shoulders, back and hips
  3. Prevents motion transferred between partners for less disturbance
Diamond Sparkle Foam provides superior pressure relief for sound sleep.
Over 1,000 micro-coil act with independent suspension to create weightless pressure relief.

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.

Diamond Sparkle Foam actively regulates your core temperature for the most natural sleeping environment. Graphene and conductive flakes dissipate heat from the surface of the skin.
