About This
- 40% Bamboo Fiber + 60% Polyester
- 【Upgrade 2 In 1 Dual Layer Design】Combines a 2 inch cooling gel-infused memory foam base with a breathable cooling fabric pillow top. The result is a plush, airy feel that promotes airflow and minimizes night sweats for deeper sleep.
- 【Relieve Pain & Contouring Support】This topper softens firm mattresses and relieves pressure for all sleepers. Slow-rebound memory foam eases pain and keeps your spine aligned. The medium-firm design perfects your bed’s comfort, revives old mattresses and extends their life at a great value.
- 【Ultra Cooling & Breathable】The innovative fiber pillowtop cover uses special weaving tech for a silky cool touch and better airflow, ideal for hot sleepers. The tight, brushed microfiber is soft, breathable and skin-friendly. Combined with gel-infused memory foam, it dissipates excess heat and keeps the surface fresh and breathable.
- 【Secure Fit for Various Mattress Heights】The elastic deep-pocket skirt fits mattresses up to 21" thick, keeping the topper firmly in place without shifting. Compatible with most mattress types, including memory foam, hybrid, innerspring, and more.
- 【Safe, Certified & Guaranteed】Made with CertiPUR‑US certified memory foam and OEKO‑TEX Standard 100 textiles, free of fiberglass and harsh chemicals. This topper is vacuum‑packed; please lay it flat in a ventilated area for 48–72 hours to fully expand, remove odors and restore fluffiness. We offer reliable support and a satisfying solution whenever you need us.

Tired of Waking Up Hot and Uncomfortable?
Most people don’t realize that poor-quality bedding traps heat and blocks airflow, leading to restless nights and constant discomfort.
Synthetic fabrics, low breathability, and heavy materials can make your bed feel warm, sticky, and irritating — especially during warmer nights.
If you’re constantly searching for “cooling bedding” or “best sheets for hot sleepers,” you’re not alone.
