8 queen mattress

Common materials include memory foam (sometimes gel‑infused), high‑density base foam, bamboo‑charcoal–infused memory foam, and—in some models—an innerspring layer such as Bonnell coils.

These are labeled as 8 inches thick. Queen dimensions are typically about 80 inches long by 60 inches wide; one listing shows a more precise measurement of 79.92" × 59.84".

Firmness varies by model and commonly includes medium‑soft, medium, medium‑firm, and extra‑firm options.

Common cooling features include gel‑infused memory foam or cooling gel particles, breathable foam layers to improve airflow, and infusions such as green tea or charcoal that are marketed to help regulate temperature.

Covers range from removable, zippered and machine‑washable covers to fixed polyester/stretch‑knit covers. Care instructions vary by model—removable covers can generally be machine‑washed, while non‑removable covers typically require spot cleaning.

These mattresses ship compressed in a box (bed‑in‑a‑box) and typically need about 24–72 hours to return to full shape; many listings specifically cite 48–72 hours for full expansion.

These mattresses are described to offer body‑contouring pressure relief, support aimed at promoting spinal alignment, and motion isolation to reduce partner disturbance.

Warranty lengths vary by listing and include 10‑year limited warranties, 1‑year limited warranties, 90‑day limited warranties, and 30‑day limited warranties.
