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.)

Luxury Mattress for real!!!
Size: Full
Set name: 12'' Medium
The only thing that I can really say is that I haven't slept this good on a mattress for a very long time. I can finally sleep through the night without waking up in pain!!! This mattress is extremely comfortable and I would buy another one if I really need to in a heartbeat without hesitation. It's not too Firm and not too soft. If there is the perfect comfort and support this is it!!! This is my opinion and my wife's opinion. She loves it as much as I do!!!

For the price excellent purchase!
Size: King (U.S. Standard)
Set name: 12'' Medium
The edges could be firmer but are better than others. Could have got a more firmer mattress but surprisingly this one seems to work! Nothing hurts when I wake up in the am. Not my shoulder, back nor my knees!

Great bed for plus size individuals!
Amazing bed ! I got it 3 days early and it is incredibly soft and plush. I cannot feel the springs at all I’m on the more plus size side and this bed feels great for my leg and back pain I 100% feel this bed is worth the price yes it’s a bit on the pricey side but it is so worth it you won’t be disappointed at all ! If I had to buy it again I would definitely. The firmness is perfect for me too great support , doesn’t sink to much and is the perfect amount of firmness all in all I recommend it especially for plus size individuals if you’re worried about being to heavy or big on it don’t be it’s perfect !

Too soft. No edge. Doesn't cool.
This bed, despite the great reviews, was anything but great. It's too soft. No support. We sinknto the middle of roll off the side because there's also no edge strength. And it doesn't cool. And now returning is going to be a nightmare.

Great mattress!
So far so good!! I’m enjoying the firmness and support, no squeaks or noises, and I can get out of bed without waking my baby up. Very happy with this purchase. After I got it out of the box, I let it expand undisturbed for 72 hours, and it expanded to the full 12 inches.
