DIY Truck Bed Mattress: Your Guide to Comfort on the Road

So you’ve got a truck, you’ve got a sense of adventure, and you’ve got the desire to take a comfortable snooze under the stars. What’s stopping you? Oh right, the hard bed of your truck.

But before you run off to spend hundreds of dollars on a pre-made mattress, consider crafting your own DIY truck bed mattress. In this guide, we’ll walk you through all you need to know to create your dream DIY sleeping surface.

Why Consider a DIY Truck Bed Mattress?

You might be asking, “Why DIY?” After all, there are plenty of commercial options available.

  • Customization: A DIY approach allows you to customize the mattress to fit the exact dimensions and quirks of your truck bed.
  • Cost-effective: Materials for a DIY mattress can be more budget-friendly than buying a new mattress.
  • Material Control: You can select the specific types of foam or other materials you prefer.

DIY Truck Bed Mattress: Getting Started

Embarking on your DIY journey requires a bit of planning and a few supplies.

Supplies Needed

  • Measuring tape
  • High-density foam
  • Mattress cover or fabric
  • Adhesive spray or fabric glue
  • Scissors or foam cutter


Measure the dimensions of your truck bed accurately. Consider the wheel wells, and whether you’ll build around them or over them.

DIY Foam Mattress for Truck Bed

One of the most popular materials for a DIY truck bed mattress is foam. Here’s why:

  • Comfort: Foam provides ample support and cushioning.
  • Durability: High-quality foam can last for years.
  • Temperature Control: Certain types of foam offer better air circulation.

Types of Foam

  • Polyurethane Foam: Affordable and widely available
  • Memory Foam: Contours to the body but retains heat
  • Latex Foam: Durable and natural but can be expensive

The Importance of Material and Thickness

The material you select, along with its thickness, can significantly impact your sleep quality.

  • Material: Natural materials like latex foam are hypoallergenic but more costly.
  • Thickness: For adequate support and comfort, aim for at least a 4-inch thick mattress.

How to Cut and Assemble Your DIY Mattress

This part is where the action begins.

  1. Mark the Dimensions: Use a chalk or marker to draw your truck bed dimensions on the foam.
  2. Cutting: Use a foam cutter or an electric carving knife to cut the foam. Ensure the cuts are clean.
  3. Glue Layers: If you are using multiple layers of foam, glue them together with a strong adhesive spray.
  4. Cover: Sew or glue a cover made of a material like cotton or polyester.

Crafting a DIY mattress is exciting, but watch out for these pitfalls:

  • Inaccurate Measurements: Always double-check your measurements.

Truck Bed Mattress Accessories to Consider

Accessories can enhance your DIY mattress experience.

  • Pillows: Consider DIY pillows that match your mattress.
  • Storage Bags: DIY storage solutions can keep your mattress safe.


Creating a DIY truck bed mattress isn’t just about the final product; it’s about the process, the customization, and the satisfaction of sleeping on something you made yourself.
