Features
- Indulge In Deep, Luxurious Sleep Every Night - This luxurious hybrid mattress king features an advanced scientific structure ratio, which provides excellent alignment protection for your spine, fully relaxes your entire body muscles, eliminates pain, offers a soft and comfortable enveloping sensation and stable and long-lasting support. Coupled with the dual heat dissipation effect of condensation and ventilation, it is precisely the long-lasting comfortable mattress you have been expecting.
- Three Upgraded Support Systems - The king size mattress has enhanced the built-in three types of pocket springs, improving the overall durability and stable support of the mattress. It conforms to ergonomic principles to provide excellent alignment protection for the spine. The edges feature three rows of sturdy anti-sagging support, while the middle provides specific cushioning support for the waist and back. It is suitable for all sleeping postures and various groups of people.
- Superior Motion Isolation for Undisturbed Serenity - The firm king mattress is equipped with hundreds of individually pocket springs that work independently to deliver outstanding motion isolation, effectively absorbing vibrations and noise caused by a partner's movements. This makes it the ideal choice for shared bedrooms and light sleepers, allowing you to enjoy deep, undisturbed sleep.
- Luxury Euro Top & 5-Layer Comfort Design - The five-layer comfortable layer of the mattress king size works in harmony to achieve the best comfort balance. The breathable and skin-friendly Euro Top and cooling gel-infused foam enhance air circulation, effectively dissipate heat and sweat, and continuously keep the sleep cool. The mattresses are selected from high-quality and safe materials without fiberglass or harmful substances, providing a healthy guarantee for you and your family's sleep.
- King Mattress in a Box & Universal Compatibility - The king bed mattress is designed for easy transportation and setup, and is widely compatible with standard bed frame types (including platforms, adjustable, and slat bases). 2026 Upgraded 14-inch king size mattress is more sturdy and durable, with a maximum weight capacity of 1200 pounds. When opening the package, please maintain a safe distance to prevent the mattress from rapidly expanding and bouncing onto people.

Each mattress is rigorously inspected by authoritative quality control, featuring excellent quality. This luxurious hybrid king mattress has passed CertiPUR-US certification, complies with the US flame retardant standards, and offers a 365-night trial period, 10-year support, and accessible 24-hour customer assistance, ensuring your peace of mind during after-sales service.

It is fantastic my 9-year-old loves it. I had to beg her to let us put a sheet on it because it was so soft. It fits in the top of her bunk bed with enough room for her to wiggle around.

Great value for the price point! Firm, comfortable and supportive.

I got this twin mattress for my guest room and it feels well balanced right out of the box. After full expansion, it settled into a true medium-firm feel that offers good support without feeling stiff. The combination of gel memory foam and pocket springs does a nice job reducing motion, which is noticeable even with movement nearby. Edges feel reinforced and don’t collapse when sitting. Temperature stays comfortable through the night, and setup was easy on a standard frame. Overall, it’s a solid, comfortable mattress that works well for everyday sleep.
