[Genuine 36D Density | Beware of Too Light 36D] The durability (lifespan) of urethane mattresses is determined by density! Using genuine 36D urethane, it is expected to last over 8 years under appropriate conditions. TIP: 0.18915m3 × 36kg/m3 ≒ Theoretical 6.81kg - For the same size, approximately 6.8kg or more is the standard. This product weighs over 7kg (approx. 8kg including cover), making it 36D in name and reality. Competitors' 36D claims with a total weight of 4-5kg are theoretically equivalent to about 21-26D and are too light to be called 36D.

[Why 220N Firmness is Comfortable] 220N, which is neither too soft nor too hard, prevents the body from sinking and maintains the S-curve of the spine. ① Suppresses lower back sinking and maintains the proper height of the pelvis to lower back, ② Supports the body evenly and disperses pressure (reduces localized pressure on shoulders, hips, etc.), ③ Supports turning over with moderate rebound, making it less likely to interfere with blood flow and body temperature regulation, ④ Synergistic effect with high-density 36D reduces the feeling of bottoming out and provides stable support, ⑤ Reduces concentrated load on the same area, relieving stiffness upon waking (does not guarantee medical effects). *Experience may vary depending on body type, preference, and base combination.

[Abrasion Resistant, Wrinkle Resistant | Thick Sandwich Fabric] Resists friction from turning over and getting in/out of bed, preventing pilling and fabric stretching, maintaining appearance and feel for long-term use. Elastic three-dimensional knit fabric is wrinkle-resistant, and the surface remains flat and comfortable even under sheets. The spacer creates an air layer that releases heat and moisture, reducing stuffiness and keeping you comfortable and dry even in sweaty seasons. Point contact allows for good skin separation, making it comfortable to use year-round.

[Peace of Mind Even in Rainy Season | Non-slip, Moisture-proof, Waterproof Bottom + Thick Dustproof Storage Bag] The underside is made of high-density Oxford waterproof fabric (polyester ox / PU, TPU coating) with silicone anti-slip dots. It is resistant to slipping on flooring, tatami, and carpets, and blocks moisture and cold air from the floor, reducing the risk of condensation and mold.
