Selectable Firmness
Firmness Info Here is where size really matters, whether you range from being heavy-set to sleeping like a contortionist, Nighslee memory foam mattresses are firm enough to avoid collapsing. They suit any body type or sleep position. They are a medium firmness. 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.
The SleepOvation mattress is meant to relieve back-pain and correct your sleeping posture, it does feel on the firmer side but not because the mattress itself is firm - but because it's correcting your spine. It's actually a very comfortable plush mattress, but someone who suffers from severe back pain, will feel the mattress to be much stiffer than someone with a healthy spine.
It's difficult to compare our mattress to the traditional firmness standards of other mattresses simply because nothing like the 700 tiny mattresses exist.

Mattress Construction

  • 3" Temperature-Neutral Cooling Memory Foam
  • 2" Bamboo Comfort™ Eco Comfort Foam
  • 5" Supportive High Density Base Foam
  • Fire Sock
  • Bamboo Jacquard Cover
3 layers of construction:
  • Premium Airflow Gel Foam
  • Premium Memory Foam
  • Premium Support Foam
NB: The composition and thicknesses vary based on selected firmness.
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.
Comfort Info Sleeping hot on memory foam is a thing of the past. Our patented cooling AirGel keeps the heat at bay leaving you cool and comfortable throughout the night. As most memory foam mattresses tend to sleep hot, ours will not. 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.
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.
Support Info Dynamic Pressure Relief
A smart mattress which knows where you need more support and where you need to be cuddled and cradled.
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.
700 "Tiny Mattresses" For Absolute Spine Support
Our independent suspension distributes body weight to relieve back pain, discomfort, and restlessness caused by sheet foam layers in other mattresses.
Comfort Specs We poked some fancy holes in the mattress (in an effective way, of course) and dropped some AirGel in the mix to create the best possible airflow in any memory foam mattress. Nighslee's patented Temperature Regulating AirGel™ increases the airflow and moves heat away from your body. 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.
Cooling Air Channels
Avoid the headaches of sleeping hot and sweaty on sheet foam or other advertised "cooling" technology that do little to prevent heat. Our air channels are designed to maintain cool temperatures for a refreshing night's sleep.
Support Specs Perfect Support
Have you seen 'The Money Pit?' Don't find yourself stuck in a mattress. Our 7-inch support layer provides an ideal base for an uninterrupted sleep.
Like billions of tiny independent cushion pocket-coil springs, this premium support foam layer supports sleepers while eliminating motion transfer during the night. 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!
Fabric Specs An ECO-Friendly Hypoallergenic Dust Mite Resistant design for the Bamboo Cover, Nighslee mattresses are designed to keep away mold and bacteria to keep you and the little ones safe. 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.
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.
