Sleepmax Serene 14" King Hybrid Mattress with CertiPUR-US Gel Infused Memory Foam & Pocket Springs, Oeko-Tex Certified Fabric & Fiberglass Free Fire Retardant Protection

[This review was collected as part of a promotion.] Never thought a mattress in a box would be this comfortable! Have used it for a month now and can say that it has stayed firm while still plush where it counts. It fully expanded in less than a day and I immediately slept great. Awesome value.

[This review was collected as part of a promotion.] Sleep Max Serene 12-Inch Hybrid Mattress Review I recently purchased the Sleep Max Serene 12-Inch Hybrid Mattress, and I have to say, it exceeded my expectations in comfort, support, and overall sleep quality. From the very first night, I noticed a huge difference in how rested I felt. Comfort & Support: The hybrid design—combining memory foam with individually wrapped coils—strikes a perfect balance between softness and firm support. The top layer conforms nicely to the body, relieving pressure on my hips and shoulders, while the coils underneath give just enough bounce and structure to keep my spine aligned. Motion Isolation: One of the standout features is the motion isolation. I share the bed, and even when my partner moves during the night, I barely feel a thing. That's been a game changer for uninterrupted sleep. Cooling: I tend to sleep hot, but the cooling gel-infused memory foam actually does help regulate temperature. It doesn't feel overly warm or trap heat like some other foam mattresses I've tried. Build Quality: The materials feel durable and well-constructed. There was a slight off-gassing smell when first unboxed, but it dissipated quickly within 24 hours. Overall Rating: 9/10 For the price, the Sleep Max Serene 12-Inch Hybrid Mattress offers outstanding value. It's supportive yet plush, cool without being stiff, and seems built to last. I'd definitely recommend it to anyone looking for an affordable luxury mattress.
