Double mattress 140 cm wide, 25 cm high, hybrid spring mattress with memory foam and breathable knit fabric for adults (bed frame not included) (135 x 190

【Durable and Superior Firmness】: This mattress features a four-sided Bonnell spring system with individually wrapped coils and FR foam, providing both softness and support. The foam layer also offers firm edge support and minimizes motion transfer, ensuring it won't disturb other sleepers. Hybrid Mattress: The 10-inch hybrid mattress combines memory foam with the traditional support of a spring mattress for a medium-firm feel, perfect for children's rooms, guest beds, or as an affordable low-profile option. A plush layer of memory foam helps align the spine to minimize pressure points for added comfort. 【Temperature Regulates】: If you tend to sleep hot, you might prefer a more breathable mattress. This mattress contains small ventilation pockets to promote airflow and prevent body heat from becoming trapped inside. [Low Danger]: The squeaking noises of a noisy mattress can be a nuisance. Unlike 3-zone mattresses, 7-zone pocket springs have more zones to provide extra support to your body's contours, effectively absorbing any movement or weight on its surface and creating a quiet sleeping environment. Mattress in a Box: Vacuum-packed and rolled: Rolled mattresses have the advantage of being easy to transport, especially to upstairs bedrooms. After receiving the mattress, please wait patiently for 24 to 48 hours to ensure it fully expands to its original height.
