From the transformable furniture brand TATAMU®, the stacking stool 'MORPHIN' (Morphin), which can switch roles between table and stool depending on the scene, is newly launched.

Emol Co., Ltd. (Tachikawa City, Tokyo; Representative Director: Koji Takahashi), the developer of TATAMU®, a transformable furniture brand that combines ergonomic space utility with a safe and comfortable user experience, announced the launch of "MORPHIN" (hereinafter "Morphin"), a stackable stool & table, on April 2, 2026.

**About the TATAMU® Brand**
TATAMU® is a furniture brand that captures human somatosensory perception to create new furniture values that are safe, easy to use, and highly space-efficient. It's not just foldable furniture; it's characterized by its ergonomic comfort and safety.
* TATAMU is a registered trademark of Emol.

**Switch your lifestyle with one piece of furniture**
Morphin is a multifunctional stool born from the TATAMU® series' concept of switching roles based on lifestyle scenes. It functions as a comfortable cushion stool and, when flipped over, becomes a flat tabletop usable as a side table. It also supports stacking for storage.

**Sit, Place, Stack**

**Switch design: becomes a stool or a table**
Furniture for sitting transforms into furniture for placing. The switch design allows roles to be changed with a simple action. Whether for relaxation time or enjoying coffee, a single piece of furniture adapts its role to the scene of your life.

**"Stacking" - The TATAMU® Concept**
One of TATAMU®'s philosophies is the concept of "stacking." Morphin can be stacked beautifully for compact storage, taken out and used only when needed. The design aims to maximize space by increasing functions rather than the number of furniture pieces.

**Commitment to Sitting Comfort**
**Firm seating comfort to support relaxation**
TATAMU® is operated by EMOOR, a health furniture brand. We are a group of specialists in sleeping and sitting. When used as a stool, the cushion with moderate elasticity supports a stable sitting posture.

**Use as a side table or ottoman**
You can use it as a side table next to your sofa, or flip it over to use it as an ottoman when you want to relax. The strength of Morphin lies in its ability to be used in the shape you need, only when you need it.

**Easily sit down, and it supports you firmly**
The seat height is approximately 45cm, slightly higher than a dining chair, making it easy to stand up and sit down. It is useful in various situations, not only in the living room but also in the entrance, kitchen, and bedroom.

**Design considerate of stacking too**
The frame is equipped with felt to prevent scratches. It is also attached to the underside of the frame to prevent scratches when stacked.

**Lightweight and compact design for easy use**
With a lightweight design of approximately 3.7kg, it is easy to carry and can be smoothly moved to where you want to use it. It is a convenient size for limited spaces such as store or office meeting areas, small homes, and studio apartments.

**Elegant colors that harmonize with your space**
The TATAMU® brand consistently adopts calm, traditional Japanese colors throughout its series. The unobtrusive colors allow for long-term use and are designed to harmonize with any scene requiring "folding," whether at HOME, OFFICE, or STORE.

**Craftsmanship with a meticulous Japanese perspective**
The table surface is made of easy-to-clean material. In addition, scratch-resistant caps are attached to the legs so it can be used not only on flooring but also on tatami mats. It is delivered assembled and compact, so you can use it from the day it arrives.

**Minimalist design that creates "space" in your life**
