{{King Size Bed in a Box}}- The mattress is compressed and rolled into a box, which can be easily transported to the door for installation. Remember to keep enough distance from the mattress when unwrapping, because it may cause injury to bystanders when expanding. Please be patient and wait for 48-72 hours for it to fully expand. It is suitable for a variety of frames, such as box springs, slatted bases, flat platforms, adjustable beds, and even floors. {{Isolated Motion}}- pocket spring mattress is supported by hundreds of reinforced pocket coils, each working independently to be noiseless and reduce the vibration of bed motion. Therefore, your deep sleep will never be disturbed by your partner’s turning over or getting up. King Mattress Measures 76" W x 80" L x 14" H and supports a maximum weight of 750 lbs {{Better Support and Back Pain Relief}}- This medium firm mattress contains multiple support layers that allow the mattress to fit exactly every part of your body. As the pressure on the shoulder, back, spine, and buttocks can be evenly distributed, the pressure point where the body contacts the mattress can be relieved, helping to eliminate your physical fatigue and pain.
