SSOOOK Mattress System (SMMS™)
: Stability perfected through canine ergonomics
For over 25 years of making pet beds, we have learned that using the same methods and materials as human mattresses cannot provide the right sleeping environment for pets. The reason is simple: pets have a completely different body structure from humans.
While the human body is a flat oval shape from front to back, pets have a cylindrical body structure. Because of this, they roll easily from side to side, and even while sleeping, they unconsciously keep their muscles tense. This is why dogs often curl up into a ball when they sleep.
SSOOOK spent over 10 years researching pet mattresses and developed the SMMS™ (SSOOOK Modular Mattress System) so pets can relax their muscles and sleep as comfortably as humans do.
SMMS™(SSOOOK Modular Mattress System)
Dogs have a natural instinct to dig into the ground or create a hollow space to rest in. This behavior originates from the wild, where they sought protection from heat, cold, and external threats while creating a more secure and cozy resting place. Even indoors, when dogs scratch at cushions or blankets, it is simply an extension of this instinct.
SSOOOK designed its mattress to respect these instincts, creating a sleep system exclusively for pets that aligns with their natural behaviors.
1. Stable, Non-Tilting Structure
Conventional cushions are often built with a simple top–bottom–side structure. When weight shifts to one side, the opposite side lifts or bulges, reducing stability. As a result, pets struggle to maintain a comfortable position.
The SSOOOK mattress solves this problem with a 23-facet three-dimensional structure. Even if a pet steps on one side or shifts its weight, the mattress maintains perfect balance, providing unwavering stability in any posture.
In addition, size is determined not merely by width and length, but by the optimal space ratio in which pets can turn freely from side to side without their legs extending outside the mattress.
2. Zoned Cushioning Materials
The SSOOOK mattress is designed with a dual-zone filling structure, dividing the center and perimeter to provide optimal cushioning based on body shape and weight distribution. The body is unified, but the materials and performance are functionally differentiated.
1) Center Zone
Filled with ultra-light, soft 0.7D microfibers, the center provides a gentle, plush cushioning. With lower rebound but superior resilience compared to the perimeter, it resists clumping over time and delivers a consistently soft and secure feel.
2) Perimeter Zone
The edges, where pets rest their heads or press their bodies, use AF bounce fibers with greater elasticity and durability. Stronger in rebound than the center, they ensure firm support that won’t collapse easily.
This dual-filling system — soft at the center and firm at the edges — ensures that pets enjoy both comfort and stability, no matter how they rest.
Why do pets stay calm in SSOOOK products?
The reason is that almost every SSOOOK product incorporates the SMMS™ system.
By combining instinct-respecting design, non-tilting stability, zoned cushioning, and body-specific proportions, SSOOOK provides pets with a profound sense of security. This is why pets naturally relax and become calm inside SSOOOK products.
Give your beloved pet the gift of true stability with SSOOOK.
