Features

  • {{Cool Sleep On A Breathable Mattress}}- Compared with mattresses made of single material, LMANKBK hybrid mattresses are generally cooler and more comfortable. The skin-friendly fabric and the perforated memory foam promote heat dissipation, the individually wrapped coil structure underneath enhances the air flow inside the mattress, keeping you cool and comfortable for the whole night.
  • {{Better Support and Back Pack 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.
  • {{Isolated Motion}}- LMANKBK 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 partners turning over or getting up. King Mattress Measures 76" W x 80" L x 12" H and supports a maximum weight of 750 lbs.
  • {{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.
  • {{Quality Guarantee}}- LMANKBK mattresses are covered by a 10-year warranty and 30-day refund policy. If you have any questions, please feel free to contact LMANKBK customer support team at any time.

Besides being an amazing value, it’s really perfectly comfortable. Not too soft and not too hard. Medium firm. Have been getting really good sleep. I’m happy.

This has to be one of the best mattresses I’ve ever slept on ! It’s extremely soft, after years of getting hammy down beds this was my first actual NEW mattress buy and I’m so glad I did it ! Firm, soft and when ever my husband lays on the bed he’s out like a light in 5 minutes

  • LOVE MY NEW MATTRESS
Size: Full Style: 12 Inch
Got it for my first apartment and it is just right for me. On the edges it’s a little softer but overall, it’s a nice balance between soft and firm. I have back problems and it’s a good bed for me. I’ve had it for a month now and it’s good. No complaints. Great value for the money.

  • Ok for the money
Size: Medium King Style: 12 Inch
The mattress was ok for the money. After unpacking an waiting for the full expansion it was a little lumpy on top. So when you have yours sheets on it is not flat and smooth. It is comfy and soft. Very heavy box stuffed in a big box. I got a king size, it is about 4 inches short for our frame. Not sure why as it is a King size. It does measure 12 inches. ... show more
