Not All Wood Boards are Built the Same

If you look closely at a piece of modern furniture, the boards inside look and behave differently from one another. Yet, the real differences between MDF, PB, and multilayer board are often unclear to most shoppers.

Understanding engineered wood is not about comparing it to solid wood. It is about understanding how different wood structures solve different mechanical problems solid wood cannot.

By varying the density, chip size, and grain direction of the wood fibers, engineered boards can be tailored for specific jobs. Here is a look at how these boards differ under the surface, and how each one functions inside your home.

E0 MDF

Thin Panels Built for Cabinet Backing

Medium-density fiberboard (MDF) is made by grinding unused timber into fine wood powder, mixing it with glue, and pressing it under high heat and pressure.

MDF creates smooth and dense sheets that can be sliced thin without splitting or fraying at the edges. Solid wood or coarse chipboards would crumble or warp at this thickness.

We use E0 Grade MDF for the back panels of our storage systems and the shelves of our No. 1 Study Desk. It creates a lightweight enclosure that keeps dust out of the cabinets with built-in gaps for ventilation, while giving our study desk shelves a completely smooth, refined surface.

Since fine wood powder requires relatively more glue during production, using a high safety standard is critical. Our E0 Grade MDF ensures strict control over chemical emissions.

F4-Star Solid Wood Particle Board

Stable Boards for Large & Flat Surfaces

Unlike MDF, high-density solid wood particle board (PB) is made from larger wood chips or shavings pressed together into solid panels.

Because of the larger particle size, this board requires less glue to bind together than MDF. These larger wood particles are pressed in alternating orientations, creating a matrix that resists internal tension. While fine MDF is built for thinness, particle board is built for flat structural volume. This gives large and wide panels the multi-directional strength needed to stay stable over time without bowing under their own weight.

We use particle board for the main structure of our Cube and Plus Storage Systems, and Little House Bed Range. To ensure safety in sleeping and living spaces, our PB meet the Japanese F4-Star Grade, the highest global standard for low emissions.

E0 Solid Wood Multilayer Board

Strong Boards for Heavy Support & Curved Edges

Solid wood multilayer board takes a completely different approach. Instead of wood powder or chips, it is constructed by cross-laminating thin sheets of solid wood in perpendicular grain directions.

This layered structure gives it high strength and flexibility. It can support heavy structural weight while being shaped into tight, rounded profiles that would cause solid wood to crack along its grain line.

We use multilayer board for load-bearing pieces like our Big Eyes Bed frame, No. 1 Chair, and Any-way Range. We leave the multilayer edges exposed to highlight the internal quality of our knot-free layers, finished with natural white oak veneer. Our multilayer boards are certified E0 Grade for safety.

The Right Material for the Right Purpose

Each engineered board is designed with a specific density and structure in mind. By matching the physical properties of the board to the exact mechanical demand of the part, we build furniture that remains beautiful, durable, and safe.
