The Therapedic NYX Twilight Luxury Plush is a soft, pressure-relieving mattress built with organic cotton, Joma® memory wool, natural organic latex, and thousands of coils. It delivers a plush feel on top with strong, stable support underneath, and it sleeps noticeably cooler than foam-based mattresses. The comfort comes from the materials and the construction—not thick layers of foam—so the mattress holds its feel and structure far longer over time.
Inspired by Nyx, the Greek goddess of night, this mattress is designed for people who want a truly comfortable bed without overheating, sinking, or worrying about materials breaking down. The feel is inviting and plush, but the support system underneath keeps your body aligned and the mattress performing night after night.
Instead of memory foam or synthetic fillers, the NYX Twilight Luxe Plush is built with carefully selected natural materials that breathe, respond, and regulate temperature without trapping heat. Each layer plays a specific role in comfort, airflow, and long-term durability, working together to create a plush feel that stays supportive over time..
100% Organic Cotton Cover
The sleep surface is wrapped in 100% organic cotton, chosen for its soft hand, breathability, and natural moisture control. Unlike synthetic knit covers that can feel warm or clammy, organic cotton allows air to move freely across the surface of the mattress, helping regulate temperature and create a cooler, more comfortable sleep environment night after night.
PURLOFT® Wool FR Fiber
Quilted into the mattress is PURLOFT® wool fire-retardant fiber, which provides natural flame resistance without the use of fiberglass or chemical treatments. Wool is inherently temperature regulating, helping keep you warm in cooler conditions and cool when temperatures rise. It also wicks away moisture, reducing heat buildup throughout the night.
JOMA® Organic Memory Wool
JOMA® Organic Memory Wool adds a gentle cushioning layer that conforms to the body while remaining breathable. Unlike foam, this wool layer does not trap heat or break down over time. It helps absorb and release moisture, contributing to a dry, comfortable sleep surface and enhancing pressure relief at the shoulders, hips, and lower back.
2″ 100% Organic Plush Latex
The primary comfort layer is 2 inches of 100% organic plush latex, providing responsive pressure relief without the sinking or slow recovery associated with memory foam. Latex naturally pushes back to support the body, maintaining proper alignment while still feeling plush. It is also highly durable, resisting body impressions and sagging far better than foam-based materials.
Each layer in the Twilight Luxe Plush is designed to complement the others—cotton for breathability, wool for temperature and moisture control, latex for pressure relief and resilience. The result is a plush sleep surface that feels comfortable right away, stays cooler throughout the night, and continues to perform year after year, without relying on materials that compress, trap heat, or wear out prematurely.
Directly beneath the latex comfort layer is a 2.4-inch micro-coil comfort layer designed to fine-tune pressure relief and responsiveness. These individually working coils compress only where needed, allowing the mattress to contour to the body while remaining breathable and supportive.
Unlike foam, micro-coils do not trap heat and do not soften unevenly. They allow air to circulate through the mattress and help prevent the “stuck” feeling often associated with plush foam beds.
Micro-coil counts (2.4″ layer):
Twin: 798
Full: 1,102
Queen: 1,353
King: 1,722
This coil layer helps the mattress feel plush without the “stuck” feeling common in foam beds. Steel is also allowed to do the work that would normally fall on foam. Steel holds its shape much better than foams in the long-term.
At the core of the mattress is a 5-zone luxury encased-coil support system, engineered to provide different levels of support across the body. Firmer coils through the center of the mattress help support the hips and lower back, while more responsive zones at the shoulders and legs allow the body to relax into proper alignment.
Each coil is individually encased, allowing it to move independently. This reduces motion transfer, improves weight distribution, and helps the mattress maintain its structure across the entire sleep surface.
Support coil counts:
Twin: 656
Full: 934
Queen: 1,128
King: 1,401
Total coil counts (support coils + micro-coils):
Twin: 1,454 total coils
Full: 2,036 total coils
Queen: 2,481 total coils
King: 3,123 total coils
More coils mean better weight distribution, improved durability, and a mattress that maintains its feel longer.
Steel edge pencil coils reinforce the perimeter of the mattress, creating strong, stable edges. This allows sleepers to comfortably sit or sleep near the edge without feeling like they will roll off. It also increases the usable sleep surface, which is especially important for couples.
The Twilight Luxe Plush is designed to avoid the most common problems found in modern mattresses.
No polyurethane foam
No fiberglass fire barriers
No chemical flame retardants
No reliance on materials that quickly break down
Instead, it uses steel coils, natural latex, wool, and cotton—materials chosen for durability, airflow, and long-term comfort.
The NYX Twilight Luxe Plush is designed to perform properly when paired with a solid, supportive base that allows the mattress to maintain its structure, comfort, and long-term durability. Because this mattress uses natural materials and a precision coil system, proper support underneath is essential to ensure it performs as intended for years to come.
Heavy-Duty Foundations/Boxes
The mattress is fully compatible with high-quality, heavy-duty foundations designed to provide consistent, even support across the entire surface of the mattress. A rigid foundation helps prevent sagging, maintains proper spinal alignment, and supports the mattress’s coil system from edge to edge.
Platform Beds
The Twilight Luxe Plush works well on platform bed frames that provide a solid surface or closely spaced slats. Platform bases offer a modern, streamlined look while delivering the firm, even support required for the mattress’s natural latex and coil construction.
Important note: Slats should be sturdy and properly spaced to prevent flexing or gaps that could compromise support.
Adjustable Bases
This mattress is also compatible with adjustable bases, allowing the head and foot sections to articulate smoothly without damaging the mattress. The independent coil system and flexible latex layers allow the mattress to bend and return to shape.
Natural latex and steel coils are highly durable, but they are designed to work against a stable surface. Using the correct foundation or base helps:
Maintain proper spinal alignment
Prevent premature wear or sagging
Ensure edge support performs as designed
Protect the long-term comfort of the mattress
20-Year Manufacturer’s Warranty
Mattresses to help you sleep well and live better.
