Firmness Info
Novosbed mattresses are available in 3 firmness levels, and all are covered by our Perfect Firmness Guarantee, 120 night sleep trial, and 15 year warranty. Soft: Designed for contouring and plushness without that "quicksand" feeling. Medium: Designed to offer the perfect balance of support and plush-comfort and Firm: Designed to provide firm, comfortable support, with minimal sink-in.
* Not quite right? Call Novosbed and they'll send you a Comfort+ kit for free. Unzip the mattress top cover and lay the Comfort+ layer on top. Zip the Comfort+ extender to the base and then to the top cover. Your Novosbed is softer or firmer, as needed. The whole process usually takes less than 2 minutes.
Medium feel top of the bed you need - not too firm, not too soft. Rated a 7 to 8 on the firmness scale. Maximum support - to help provide maximum support for people with high BMIs.
Medium Plush Firmness
The 700 Tiny Mattresses independently respond to each sleepers' personal weight and size. When you initially sit on the mattress, it feels very plush because all of your weight is concentrated on a few tiny mattresses. As you lie down, your weight is evenly distributed across all the tiny mattresses for a firmer and more supportive feel. The ingenuity of the "tiny mattresses" provide the back support of a firm mattress with plush comfort for a very luxurious feel.
The 6" base foam layer adds strength, durability and structure to support sleepers of all sizes, without feeling too firm.

Mattress Construction

Materials Overview
Superior long lasting comfort, motion isolation, and body contouring with high-density memory foam. 5 layers of construction:
  • Premium Airflow Gel Foam
  • Premium Memory Foam
  • Premium Support Foam

NB: The composition and thicknesses vary based on selected firmness. Weight info is based on the medium firmness.
The Helix Plus is designed for Plus Size and Big & Tall and offers maximum support with a medium feel, it has five layers of construction:
  • Tencel Cover
  • 1.5" Helix Dynamic Foam
  • 1" Gel Memory Foam (Density: 4.0 lb)
  • 1.5" Memory Foam Plus
  • 8" Body Shaped Innersprings with reinforced perimeter
  • 0.5" DuraDense Base Foam.
Our "Tiny Mattress" technology is the most significant mattress invention in the last 100 years. There is no other mattress on the market that compares to our one-of-a-kind technology and it's GREENGUARD Gold Certified.
We take a 3" piece of high density hybrid foam optimized for our technology, cut out a 2.25" x 2.25" rectangular cylinder, and then encase it in a fabric pocket. We then attach the Cushion Pocket to a .078" high carbon steel pocketed coil spring to create our patented "Cushion Pocket Spring", better known as the "Tiny Mattress". Finally, we combine roughly 700 of these "Tiny Mattresses" to create a mattress that reacts independently to personal weight and size.
3-Layer Foam Construction
  • 2" LSA200 Foam Top Layer
  • 2" Contouring Memory Foam (IFD: 9. Density: 3 PCF)
  • 6" Core Support Foam Base (IFD: 32. Density: 1.8 PCF)
  • Seamless Iconic Four-stripe Cover.
Comfort Info
InterLock Blue™ Core Cover
Knitted with advanced 2-way stretch, InterLock Blue™ adds a second layer of protection for the foam core, and a second layer of moisture guard for added coolness and comfort.
Ultra breathable cover and hybrid design increase airflow to keep the mattress cooler. No more sweaty nights.
The cover's miniature cushion pads provide an added level of comfort and the engineered air channels promote airflow, to maximize the "tiny mattress" technology.
Beautifully designed and engineered with three premium foams for cooling, body contouring and pressure-relieving core support.
Support Info
2 to 3" Premium Memory Foam
Perfect comfort and pressure relief, this layer adds 3 luxurious inches of plush support memory foam to the heart of your Novosbed.
The new Helix Plus has higher density foams to match heavier sleepers and provide increased durability. The coil unit has best in-class edge support, so plus size sleepers never feel like they're falling off the mattress. An extra layer of high density, 4 pound foam is included in one of the three foam layers to help provide maximum support for people with high BMIs.
700 "Tiny Mattresses" For Absolute Spine Support
Our independent suspension evenly distributes body weight to alleviate stress on the natural curves of the spine. In addition to relieving back pain, this provides absolute comfort for your preferred sleeping position.
The Leesa mattress is designed to cradle and support your body while avoiding the sinking feeling and overheating found in other foam mattresses.
Comfort Specs
2" Premium Airflow Gel Foam
A highly breathable gel memory foam for ultra-luxurious comfort with heat dissipation far superior to that of traditional memory foams.
Our special latex-foam hybrid alternative, designed to be denser to contour to your body.
Uniquely pressure relieving, we use 4 pound Memory Plus Foam - a special, ultra dense and extra durable Helix blend.
Cooling Air Channels
Our individually sealed cushions create air channels with cool and steady airflow management. Contrary to hot and sweaty sheet foam mattresses, you'll sleep undisturbed and awake refreshed the next day.
LSA200 Foam
The 2" foam top layer provides airflow for a cooler night's sleep and enough bounce for freedom of movement.
Support Specs
Like billions of tiny independent cushion pocket-coil springs, this premium support foam layer supports sleepers while eliminating motion transfer during the night.
Firm Memory Foam provides ergonomic support and cushioning, the transition layer has a higher IFD to match your body type. Extra support.
Hundreds of individual taller coils designed to cradle and support heavier weight. Reinforced perimeter to provide edge support.
The bottom foam layer of the mattress provides base support and durability to the entire mattress.
Individual Vertebrae Support
The individual suspension system supports each bone (33) in the human spinal column separately. It cradles the body's curves while providing enough firmness for the back's muscular and bony structures. Plus it's Chiropractor Endorsed!
Pressure Relieving Memory Foam
The 2" memory foam layer delivers the body contouring and pressure relief you've come to expect from memory foam.
Fabric Specs
Ultra-soft, Moisture-wicking, Washable Cover
Made from eco-friendly Tencel® fabric, the luxurious Novosbed top cover draws moisture away from your body for a cool, dry night. It is also removable and machine-washable.
Each Plus mattress comes with our Ultra Breathable Tencel technology designed to increase airflow and to keep you cool.
Our stretch knit polyester and elastane cover is designed to complement the "tiny mattresses" ability to adjust to personal weight and size. More specifically, we've integrated a quilted, internal (FR) mattress pad that offers a more plush level of comfort. This zip-off removable and washable cover allows access to independently sealed cushions and unmatched cleanliness (vacuum in-between each air channel so you can eliminate dust, bacteria, and allergens).
The Leesa Mattress is wrapped in our iconic four-stripe cover that features fire retardant properties.
