Features 6
- 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 medium 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 12-inch king size mattress is more sturdy and durable, with a maximum weight capacity of 1000 pounds. When opening the package, please maintain a safe distance to prevent the mattress from rapidly expanding and bouncing onto people.
- Expertly Crafted By Professionals - FANSACE is a professional R&D manufacturer with years of experience, dedicated to bringing you advanced sleep. 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. (For a perfect sleep experience, it is recommended to allow the mattress to expand for 24-72 hours.)

Love this mattress
Size: King (U.S. Standard)
Set name: 12'' Medium
Was delivered by FEDEX on time. Easy to open although box was very heavy. Inflated immediately and were able to sleep on adfter 8 hours. Very comfortable and nice mattress for the money. No motion transfer at all. It is medium firm. Don’t hesitate to order. I was sceptical because not a name I had heard before. Hope I still love it after a few months.

Better Sleep Position
Size: Queen (U.S. Standard)
Set name: 16'' Medium
Fine Medium mattress for my back issues. Allow better neck/back alignment. A little soft on edge but allows us to slide off bed better. Good price. Great Manufacturer background. Packaging 📦 was good and clean inside plastic. No smell. Watch the last cut during release because it SPRINGS OUT! Great sleep quality! Firmness is perfect for our needs. No motion construction. Recommend this product!

So far so good! 👍🏽
Size: Queen (U.S. Standard)
Set name: 16'' Medium
So far so good. Just arrived. Looks like vacuumed sealed. It DIDN'T pop open like biscuits. Its massive. Was wrapped well, it has straps! A huge plus! My wife stands at about 5'7". She needs a step stool to get in. 😆 Looks almost as good as the picture. Now? We wait... 😔 Feels soft yet firm... i put a big crater in our last mattress, so I do think ill finally get some good sleep.🤞🏼

Very comfortable!
Size: Queen (U.S. Standard)
Set name: 16'' Medium
Wow...this mattress is awesome! So very comfortable...not too firm, not too soft. My only regret is that I got the 16 inch. Almost need a ladder to crawl into bed!

Great Investment!
Size: King (U.S. Standard)
Set name: 16'' Medium
Excellent!!! Medium Firm as described. To help speed up the inflation, I turned on several fans in my room for 24 hours. Within that timeframe, the mattress was completely expanded. That first night's sleep was impeccable! I was able to get up without aches and pains. I will say that this mattress is extremely heavy (King 16"). If you have stairs, pay for the service...thank me later. Otherwise, this was a great investment!
