PRECISION PERSONALIZATION
Your Body Is Unique. Your Mattress Should Be, Too.
Most mattresses ask you to choose a firmness level. CST takes a different approach.
Using your individual Body Profile™, our proprietary Design Engine calculates a personalized mattress architecture built around your body and how you sleep.

CUSTOMER EXPERIENCES
Real People. Different Bodies. A Different Sleep Experience.
No two sleepers are exactly alike. Here's what customers have shared about their experiences with Custom Sleep Technology.
Courtney D.
A mattress built around her body
★★★★★
“After sleepless nights in pain on a mattress from a big box store, I was fortunate enough to meet Bob at Custom Sleep Technology. Bob is extremely knowledgeable and created a custom Talalay latex mattress built specifically for my body and sleep style. I absolutely love it! The mattress is extremely comfortable with just the perfect amount of softness and support.”

Dan R.
One mattress, two individualized designs
★★★★★
“We started with the body profile on the website and then talked with Bob and ordered our mattress. ... Amazing mattress! We have the custom mattress with different densities for both the left and right sides as well as shoulder and hip areas for each side. Our previous mattress was perfectly wrong for both my wife's and my body types, and we both experienced daily back pain.”

Chuck H.
An unusually personal solution
★★★★★
“Over the last year, I had to sleep on our two-cushion sofa so that I could place my hip between the cushions. At least able to sleep. Finally found CST, submitted a body profile and went to Connecticut to test it out. The ability to customize and change the mattress seemed like the best option to be able to sleep in a bed. ... A full night sleep on the first night and the sofa has been lonely since then.”

THE CST DIFFERENCE
From Your Body Profile to Your Mattress Design
A smarter, more personal way to better sleep — designed around you.
Your Body Profile™
It starts with you. Your body proportions, weight, and sleep position provide the information needed for your personalized design.
The CST Design Engine
Our proprietary technology uses your Body Profile to calculate an individualized configuration of support zones and Talalay latex layers.
Your Personalized Mattress Design
See your personalized mattress design, including the configuration of each layer and an explanation of how it reflects your individual characteristics.
WHY FIT MATTERS
Firmness Is Subjective. Precision Can Be Calculated.
Precision personalization starts by understanding how your body needs support.
Soft, medium, or firm? These familiar categories describe how a mattress feels, but they don’t tell the whole story about how it supports your body.
Firmness ratings vary between manufacturers. And what feels comfortable at first isn’t necessarily the construction best suited to your body proportions, weight distribution, and sleep position.
CST takes a different approach. Rather than assigning one firmness level to your entire mattress, our mattress Design Engine calculates how four Talalay latex layers work together to provide individualized support.
The result isn’t simply a soft, medium, or firm mattress. It’s a sleep system designed to fit you.
THE ENGINEERING BEHIND YOUR MATTRESS
Engineered Into Every Layer.
A personalized mattress requires more than choosing a firmness level.
Every layer works together to deliver support tailored to your body characteristics.
Four Layers. One Integrated System.
CST’s Design Engine specifies all four Talalay latex layers as one integrated system. Individual layers are segmented using different ILD firmness levels to create precisely placed support zones for different areas of the body.
Why Talalay Latex?
Talalay latex combines resilience, durability, and precisely specified firmness levels. These properties make it particularly well suited to CST’s personalized, multi-layer, multi-segmented construction.
Two Sleepers. Two Individual Designs.
For couples, each side can have its own calculated four-layer configuration, including different ILD levels and support zones. Because the layers are replaceable, the design can be modified as needs change.
What Is ILD?
ILD (Indentation Load Deflection) measures the force needed to compress latex by a specified amount. It helps describe the resistance, or “give,” of each layer when weight is applied.
PERSONALIZATION THAT EVOLVES WITH YOU
Designed to Adapt. Built to Last.
Your body doesn’t stay the same throughout your life. Your mattress doesn’t have to stay the same, either.
Changes in weight, pregnancy, injury, or evolving comfort needs can affect how you experience your mattress. CST’s replaceable Talalay latex layers allow us to adjust your mattress design without replacing the entire system.
One Complimentary Modification
One complimentary modification during the 10-year warranty period, whether for an initial comfort adjustment or changing needs.
Full-Refund Return Assurance
If your mattress remains unsatisfactory after the complimentary modification, it may be returned for a full refund.
Additional Adjustments: $475 per Layer
Further changes can be made by replacing individual layers for $475 per layer rather than purchasing a new mattress.
10-Year Warranty
Coverage for defects in mattress materials and workmanship.
A mattress designed around you - with the flexibility to adapt when you need it.
THE EXPERIENCE BEHIND THE TECHNOLOGY
Precision Personalization Begins With a Better Question.
Precision Personalization didn't begin with a mattress. It began with a question: What if we could calculate the precise level of support needed at specific areas of the body while sleeping?
For CST founder and inventor Bob Zukowski, the answer began with a fundamental insight: mattress support isn't simply about how much force the body applies to a sleep surface. It's about how the material responds to that force - allowing some areas to compress while providing the resistance needed to support others.
With more than 25 years of experience in sleep materials and mattress construction, Bob understood the implications for spinal alignment. Different areas of the body require different levels of support to maintain a more natural sleeping posture. His engineering background led him to explore whether those requirements could be calculated and translated into a precisely configured mattress.
That work became the foundation for CST's patented Body Profile Technology™ and proprietary mattress Design Engine, which translate individual body characteristics into a calculated, buildable mattress architecture.
