Helix | Luxe Midnight w GlacioTec Cooling | 13.5" King Mattress

Gently-Used: This mattress has little to no wear and tear, has been cleaned and sanitized, and will  be great  for many  years to come. 

Summary

The Helix Midnight Luxe 13.5″ King mattress is a premium hybrid designed to deliver a medium comfort feel with the luxury of a pillow‑top, support of zoned coils, and upgraded cooling options. It’s especially well suited for side and combination sleepers who want a comfortable, plush feel but with strong support and durability. If you lean toward very firm or minimal foam contouring, you might want to compare firmer models or check the firmness level in‑person.

Key Specifications

• Size: King — approximately 76″ × 80″ footprint, and ~13.5″ height. 

• Feel / Firmness: Medium feel (often rated around 5–6/10 “medium”) — designed to balance contouring comfort with support. 

• Mattress Type: Hybrid construction (memory/gel foams + individually wrapped coils) under the Luxe premium build.

• Cover / Top Option: Includes a premium quilted pillow‑top surface and cover options such as ultra‑breathable TENCEL™ or the optional GlacioTex™ Cooling Cover. 

Construction & Materials

• Cover & Pillow‑Top: The Luxe version features a plush pillow top for added comfort, with the choice between TENCEL™ cover or GlacioTex™ Cooling Cover (which draws heat away, for cooler sleep). Comfort / Foam Layers:

  • A gel‑infused memory foam layer (for pressure relief and cooling) lies beneath the pillow‑top. 

  • Additional high‑density and responsive foam layers beneath the memory foam to support body contouring and transition into support core

• Support Core:

  • Up to ~1,000 individually wrapped steel coils (zoned for lumbar and support) with reinforced edges for durability and structure.

• Base Layer: A dense foam foundation beneath the coils stabilizes the mattress and supports its structure. 

Performance & Features

• Pressure Relief & Side Sleep Support: Tailored for side and combination sleepers, with memory foam contouring around shoulders/hips while the coil system offers support under the lumbar region. 

• Cooling & Breathability: With the GlacioTex cover (optional) and gel‑infused memory foam plus coil system for airflow, this mattress is marketed for cooler nights. 

• Motion Isolation & Edge Support: The individual coils help reduce motion transfer; perimeter reinforcement enhances the usable sleep surface near the edges. 

• Height & Aesthetic: At 13.5″, this is in the “premium” height category — giving a luxurious look and thicker feel in bed.
