A Three-Layer System Designed for cool, comfortable sleep
Heat and humidity are the two biggest disruptors of sleep comfort. The Wamsutta Sleep System was built around that problem — three purpose-designed layers that work together to keep you cooler and drier through the night.
Temperature Regulation that pulls heat away from your body & evenly distributes, proven to reduce heat index by 3-5 degrees
moisture management to reduce humidity compared to standard microfiber bedding
Flexible, breathable fabrics that move naturally with your body during sleep for absolute comfort
STEP 1
The Pillow Engineered for cooler sleep
The Sleep System starts at the pillow, where heat and moisture discomfort most often begin. Both the Down Alternative and Latex Loft pillows are engineered with the same temperature-regulating, moisture-wicking technology, wrapped in a removable washable cover that most competitors simply don't offer.

The Mattress Layer Built for Drier Sleep
The mattress layer sits at the core of the Sleep System. Whether you choose the protector, pad, or pillow top topper, each product shares the same moisture-wicking technology and temperature-regulating fill.

The Difference You Can Feel
The best pillow I've ever had
I'm an elderly woman and have advanced degeneration in my neck and this is the only pillow that is comfortable for me.
Marilyn W.
Incredible quality, worth the price
I purchased the all seasons down comforter for our king bed. It is truly worth every penny. The infill doesn’t move around unlike most down inserts and my husband keeps saying it’s the perfect temp.
Michelle G.
This is what I was missing
I didn't realize the difference this mattress protector would make! It slides on, perfectly fitting my deep mattress. Doesn't bunch up or overheat. Really nice!

FAQs

What is the Wamsutta Sleep System?
Most bedding is designed to look good on a bed. The Wamsutta Sleep System is designed to do something more important. It's a three-layer sleep environment combining a temperature-regulating pillow, a moisture-wicking mattress layer, and a climate-control comforter. Each layer is purpose-built to reduce heat and humidity where they disrupt sleep most. Use one layer or all three. Either way, the goal is the same: a cooler, drier, more comfortable night's sleep.
Do I need to buy all three layers, or can I start with one product?
You can absolutely start with one product. Each layer of the Sleep System is designed to deliver meaningful benefit on its own, with the pillow being the most popular entry point. When you're ready, adding more layers compounds the performance and brings you closer to the full Sleep System experience.
How does the Sleep System keep me cooler and drier?
The Sleep System works by addressing the two biggest disruptors of sleep comfort: heat and humidity. Each layer is built with moisture-wicking fibers that draw humidity away from your body and disperse it through the sleep surface, and temperature-regulating materials that pull heat away from the body rather than trapping it. When all three layers are used together, they create a complete sleep environment that manages both temperature and moisture continuously through the night.
What materials are used in the Sleep System?
The Sleep System combines premium fabrics and advanced fiber technologies selected specifically for temperature regulation and moisture management. Key materials include a Tencel-spandex shell and poly-lyocell fill in the comforter, high-performance moisture-wicking fibers across the pillow and mattress layers, and breathable stretch fabrics throughout the system designed to move naturally with the body during sleep.
What other Wamsutta products work well within the Sleep System?
The Sleep System is designed to work in tandem with Wamsutta cotton sheets and duvet covers. All Wamsutta sheet and duvet fabrics are 100% cotton, which complements the system's breathability and temperature management by allowing air to circulate naturally alongside the moisture-wicking and temperature-regulating layers.

Sleep Cooler and Drier With the Wamsutta Sleep System
Experience better sleep with the Wamsutta Sleep System — a complete, purpose-designed sleep environment engineered to deliver cooler, drier comfort through the night. From temperature-regulating pillows that manage heat and moisture at the head and neck, to moisture-wicking mattress layers that draw humidity away from the body, to climate-control comforters that provide warmth without the heat trap, every product in the system is designed to work together toward one goal: better sleep.
Each layer of the Sleep System is built with advanced moisture-wicking fibers, temperature-regulating fills, and breathable stretch fabrics that move naturally with the body during sleep. Whether you start with a single product or build the complete system, every piece delivers the same core promise — a sleep environment that stays measurably cooler and drier through the night.
Backed by nearly 200 years of textile expertise and validated through both laboratory and human sleep testing, the Wamsutta Sleep System is performance bedding with proof behind it. Lab results showed a heat index reduction of 3–5 degrees and lower absolute humidity across every product in the system — consistently outperforming standard microfiber bedding. For hot sleepers, light sleepers, or anyone who wakes up uncomfortable in the night, the Sleep System was built with you in mind.
