Modular Collection Part 20-25-30 – Short Cross Members

Modular Collection Part 20-25-30

These short cross members, Modular Collection Part 20-25-30, reinforce a loft bed from side to side. They come in three sizes: 20 for Twin, 25 for Full, and 30 for Queen, each sold in sets of two. In most cases, High and Uber High loft beds use this extra bracing for structural support.

We use these cross members to build our High and Uber High loft configurations throughout the Modular Collection, including our Twin, our Full, and our Queen.

You can only use this part with our Modular Collection, or the wider Maxtrix system it's built on. If you're building or converting a High or Uber High loft bed, these cross members are one of the structural pieces you'd need.

The Design

We offer several collections of beds and bunk beds, each with its own style, materials, and construction. This Collection stands apart by using interchangeable parts rather than fixed furniture designs. A modular approach gives you greater flexibility both when you purchase your furniture and years later as your needs change.

The collection works much like LEGO building blocks. A small set of interchangeable parts allows you to create hundreds of configurations for beds, loft beds, and bunk beds. You can select any layout when you buy and later expand, convert, or reconfigure many products as your family and lifestyle change.

Materials & Finishes

Every structural part in this collection starts as premium solid hardwood. Each piece is knot-free and free of finger joints, for exceptional strength, durability, and appearance. Depending on the production run, the factory uses birch, maple, or aspen, always built to the same engineering and quality standards. Selected non-structural parts use engineered wood or wood veneer where they improve stability, consistency, or performance.

Finish quality matters just as much as the wood underneath it. These durable, low-VOC finishes create a healthier home environment and meet California's strict environmental standards. White furniture uses a durable painted finish for a clean, modern appearance. Our Natural finish uses a clear lacquer that highlights the beauty of the wood. Because wood is a natural material, products with a Natural finish may vary slightly in grain pattern and colour.

Understanding the Parts System

Every product in this collection combines individual parts that fit together to create a complete piece of furniture. Some parts appear in many different furniture configurations, while others are found only in one or two specific products.

Unlike our other furniture collections, many of these parts are also sold individually. This lets you build a new furniture configuration, replace a damaged part, or convert your existing furniture into another compatible design without buying an entirely new item.

Some parts combine several individual pieces in one box. We sell these parts as complete units and do not separate them into smaller individual pieces.

To identify a particular part, start with the complete furniture product. Open the Shipping Box Dimensions tab to view the list of shipping boxes. Each Box ID matches one Modular Collection part. Search our website using the corresponding MX Product ID to locate that item.

Hardware & Assembly

Hardware varies by part. Some parts include it, others require reusing hardware from your existing furniture or purchasing it separately, and some packages include extra hardware because different configurations use different fasteners.

Assembly instructions for this collection describe the building system itself, not one finished product. Instead of showing only one furniture configuration, they explain how individual parts fit together to create many different beds, loft beds, bunk beds, and other furniture. The first assembly may seem challenging, but it gets much easier once you understand how the system works.

Most parts that need an Allen key include one in the box. You will also need a Phillips screwdriver and a flat-head screwdriver. Power tools aren't required. For larger furniture assemblies, we recommend that two adults complete the installation.
