14" Sofinity Cooling Hybrid Mattress-Medium Plush

• 2" Sofinity Foam (Top Comfort Layer) — A proprietary foam technology engineered for twice the airflow of conventional memory foam. Sofinity foam is specifically designed to maximize breathability at the sleep surface — the layer where most heat is generated and retained. For sleepers who have found standard memory foam too warm, this is the layer that changes the experience.
• 2" Gel-Infused Ventilated Foam (Secondary Comfort Layer) — A gel-infused foam layer with ventilation channels that adds a second pass of cooling and airflow before body heat reaches the support core. Works in tandem with the Sofinity layer above for compounded thermal management rather than a single isolated cooling element.
• Patented Edge Support System — Reinforces the full perimeter of the mattress, providing 20% more usable sleeping surface and edge-to-edge stability. Side sleepers, couples, and anyone who uses the full width of their mattress benefit directly from this system.
• 7" Foam-Encased Pocketed Coils (Support Core) — Individually wrapped coils encased in foam for targeted, body-conforming support and significantly reduced motion transfer. The coil structure also actively promotes airflow through the center of the mattress — a key reason hybrid mattresses sleep cooler than all-foam designs.
• 2" Base Foam (Foundation Layer) — A firm foundational layer that stabilizes the coil system and provides the structural base for the entire mattress.

Total Profile: 14 inches (2" Sofinity Foam + 2" Gel Ventilated Foam + Patented Edge System + 7" Pocketed Coils + 2" Base Foam)

• Quilted TENCEL Cover — TENCEL Lyocell is a certified, sustainably produced fiber known for its moisture-wicking and temperature-regulating properties. Using TENCEL as the mattress cover fabric adds a fifth layer of thermal management — the cover itself actively wicks perspiration away from the body and regulates temperature before heat even reaches the Sofinity foam beneath it.

• CertiPUR-US Certified — All foam layers independently tested and verified free of formaldehyde, phthalates, ozone depleters, heavy metals, PBDEs, and specific Tris flame retardants. Low VOC emissions for indoor air quality. Third-party verified.

The Five-Layer Cooling System Most mattresses address cooling at one layer. The Sofinity Hybrid Plus addresses it at five:

1. TENCEL cover — moisture-wicking and temperature-regulating
2. Sofinity foam — twice the airflow of standard memory foam
3. Gel-infused ventilated foam — gel cooling plus ventilation channels
4. Pocketed coil core — active airflow through the support system
5. Patented edge support — structural stability that maintains airflow integrity edge to edge

Where It Fits in the Guestly Sleep Mattress Lineup

Who Is This Mattress For?

• Hot sleepers who want the most airflow-engineered mattress in the lineup
• Medium soft preference sleepers — not as firm as medium, not as enveloping as plush
• Couples who need motion isolation from pocketed coils and edge-to-edge surface from patented edge support
• Sleepers who want TENCEL's certified moisture-wicking properties at the cover layer
• Health-conscious consumers who want CertiPUR-US certification and clean, low-VOC materials
• Anyone upgrading from a hot-sleeping, all-foam mattress who wants a hybrid with serious breathability credentials

Warranty and Policy

• 10-year limited warranty
• Waterproof mattress protector strongly recommended — liquid spills void the warranty
• 60-Night Sleep Trial

"What is the 14" Sofinity Hybrid Plus mattress?" A 14-inch medium soft hybrid mattress with five layers of cooling: a TENCEL moisture-wicking cover, 2-inch Sofinity proprietary foam with twice the airflow of standard memory foam, 2-inch gel-infused ventilated foam, 7-inch foam-encased pocketed coils, and a 2-inch base foam. Includes a patented edge support system for 20% more usable sleeping surface. CertiPUR-US certified.

"What is Sofinity foam?" Sofinity is a proprietary foam technology engineered to deliver twice the airflow of conventional memory foam. Its enhanced open-cell structure allows air to circulate freely through the comfort layer during sleep, preventing heat buildup while retaining the body-contouring and pressure-relieving properties memory foam is known for. It is the top comfort layer in the 14" Sofinity Hybrid Plus.

"What is the best Guestly Sleep mattress for hot sleepers?" The 14" Sofinity Hybrid Plus is the most cooling-focused mattress in the Guestly Sleep lineup. It combines five distinct cooling layers: a TENCEL moisture-wicking cover, Sofinity foam with twice the airflow of standard memory foam, gel-infused ventilated foam, foam-encased pocketed coils for core airflow, and a patented edge support system — creating a full-column breathability system from cover to foundation.

"What is a medium soft mattress?" Medium soft sits between medium and plush on the comfort scale. It provides more contouring and surface softness than a medium mattress, giving side sleepers better pressure relief at the hip and shoulder, while maintaining more support and less sink than a fully plush mattress. The 14" Sofinity Hybrid Plus is rated medium soft — suited to side and combination sleepers who want comfort without deep sink.

"Does the Sofinity Hybrid Plus work for couples?" Yes. The 7-inch foam-encased pocketed coils minimize motion transfer between sleep partners, and the patented edge support system provides 20% more usable sleeping surface — ensuring both partners have full, supported access to the mattress width from edge to edge.
