• Hybrid Comfort System - Combines independent pocket springs with responsive memory foam. The springs provide targeted support and reduce motion transfer (ideal for couples), while the foam conforms to your body curves for pressure relief. Offers a medium firm feel – supportive yet soft enough for side/back/stomach sleepers.
• Sleek Black & Gray Design - Features a modern black top surface with stylish gray side panels. The stain-resistant, textured fabric looks sharp with any bedding and adds a premium touch to your bedroom.
• Excellent Support & Breathability - The independent pocket springs adapt to your spine alignment (great for back pain). Airflow channels between springs and foam layers, plus a breathable side fabric, prevent heat buildup ,keeps you cool all night.
• Mattress in a Box, Easy Setup - Expertly compressed, rolled, and shipped in a manageable box. Simply unbox, unroll onto your bed frame (slatted base, box spring, or floor), and let it expand within 24‑48 hours. Zero fiberglas.
• Suitable for Multiple Sleepers & Risk-Free Trial - Medium firmness satisfies most preferences – soft enough for side sleepers’ shoulders, firm enough for back/stomach sleepers’ lumbar support. Backed by a 100-night trial and 10-year limited warranty.
• Safety Notice for Unpacking- It is imperative to meticulously adhere to the prescribed unpacking procedures to prevent the mattress from undergoing rapid expansion upon exposure to atmospheric conditions, which could potentially lead to forceful impact and consequent injuries.
