What are the different types of tatami?

The Classic Choice with Timeless Appeal

When most people picture tatami, they're thinking of the traditional straw core variety. These mats have been crafted the same way for generations, using two key materials: wara (rice straw) for the core and igusa (rush grass) for the surface. The straw is tightly compressed into a thick, dense core, then wrapped in a layer of igusa that's woven into a smooth, slightly textured mat. The edges are finished with a border fabric, often cotton or linen, in neutral tones like black, beige, or indigo.

What makes this type so beloved? For starters, its natural breathability. Straw is a fantastic insulator, keeping rooms cool in summer and warm in winter. Walk barefoot across it, and you'll notice a gentle springiness underfoot—unlike hard floors, it cushions steps and reduces noise. The igusa surface has a subtle, earthy scent, especially when new, that many find calming. It's no wonder these mats have been a staple in traditional washitsu (Japanese-style rooms) for centuries.

Modern Comfort for Everyday Living

As tatami gained popularity outside Japan, manufacturers started experimenting with materials to make them more accessible. Enter foam core tatami—a modern twist that swaps the straw core for high-density polyurethane foam. The surface still uses igusa or a synthetic igusa-like fabric, keeping the classic look, but the core is lighter, softer, and more affordable.

Why choose foam core? For one, portability. These mats are much lighter than straw core, making them easy to move or store. They're also more resistant to moisture—while you shouldn't soak them, a little spills won't cause mold or mildew like straw might. Plus, they're budget-friendly, making them a great option for renters, students, or anyone wanting a tatami vibe without the investment.

That said, they do have trade-offs. The foam core lacks the natural breathability of straw, so they might feel warmer in hot weather. They also don't have the same springy texture—some find them too soft, almost like a thick yoga mat. Still, for casual use, like a home office floor or a play area for kids, they're a practical choice.

The Workhorse of Tatami Mats

For those who want the best of both worlds—durability and natural elements—multi-layer board tatami is a game-changer. These mats use a core made from compressed wood fiberboard or plywood, layered with materials like cork or foam for added cushioning. The surface is still igusa or a high-quality synthetic weave, and the edges are reinforced with plastic or fabric to prevent fraying.

What sets this type apart? Its sturdiness. The wood-based core resists warping and compression, making it ideal for high-traffic areas. Unlike straw, it won't attract pests, and it's more moisture-resistant than foam. Many manufacturers also treat the core with fire-retardant or anti-microbial coatings, adding to its practicality. It's a favorite in modern homes that blend Japanese aesthetics with Western functionality—think living rooms, home gyms, or guest rooms.

Another perk? Customization. Since the core is rigid, these mats can be cut into non-standard sizes or shapes, fitting awkward corners or built-in furniture. Some even come with interlocking edges, making installation a breeze—no need for professional help.

Tatami That Can Handle Life's Messes

Let's face it: life is messy. Kids spill juice, pets track in mud, and accidents happen. That's where waterproof tatami comes in. Designed for durability, these mats use a synthetic core (often polyethylene or rubber) and a surface made from water-resistant materials like vinyl or treated igusa. The edges are sealed to prevent water from seeping in, and the surface can be wiped clean with a damp cloth.

Don't let the "waterproof" label fool you—these mats still look and feel like tatami. The synthetic surface mimics the texture of igusa, and the core is dense enough to provide that signature softness. Some even have anti-slip backing, making them safe for bathrooms, kitchens, or entryways. Imagine having a tatami mat near your shower, where you can step out onto something warm and cushioned without worrying about mold!

While they're not as eco-friendly as traditional straw, they're a lifesaver for busy households. Parents love them for playrooms, and pet owners appreciate that fur and dirt wipe right off. They're also popular in commercial settings like spas or hotels, where easy cleaning is a must.

When One Size Doesn't Fit All

Every space is unique, and sometimes standard tatami mats just won't cut it. That's where customized tatami comes in—designed to fit your exact dimensions, style, and needs. Whether you have a tiny apartment nook, a curved wall, or want tatami integrated into built-in furniture, a tatami supplier specializing in tatami solutions can make it happen.

Customization options are endless. You can choose the core material (straw, foam, or multi-layer board), the surface (natural igusa, synthetic, or even patterned fabrics), and the border color. Some suppliers will even add features like built-in storage (think tatami mats with hidden drawers) or heating elements for cold climates. For example, a customized furnitures supplier might create a tatami platform bed with a matching mat, turning your bedroom into a cozy retreat.

The key here is working with a supplier who understands both traditional craftsmanship and modern design. They'll measure your space, discuss your lifestyle (do you have kids? Pets? Allergies?), and recommend materials that fit. While custom tatami costs more than standard mats, the result is a space that feels truly yours—functional, beautiful, and perfectly tailored.
