Mattresses

Shop Semi Truck Mattresses

A worn-out sleeper mattress makes long weeks on the road harder than they need to be. We stock semi truck mattresses in common sleeper sizes, with gel foam, memory foam, and pocket-coil options for different comfort levels and budgets. Some mattresses fit specific Peterbilt, Kenworth, Freightliner, International, Volvo, or Western Star applications. Others use universal sizing. Measure your bunk and check the listed fitment before ordering.

Gel Foam Mattresses

Gel foam offers a lower-cost replacement for many factory sleeper mattresses. Several models use a 4.5-inch convoluted foam base with a 2-inch gel foam layer for 6.5 inches of total thickness. The raised foam design allows more air to move through the mattress, while the gel layer helps manage heat. Available sizes include 28 x 79, 35 x 79, 38 x 75, 38 x 80, 42 x 80, and 48 x 80 inches.

Memory Foam Mattresses

Memory foam gives you a softer surface that follows the shape of your body. Our 28 x 79-inch option uses a 6-inch base, 2 inches of memory foam, and a 1-inch cool-fiber topper for 9 inches of total thickness. Other options include 42 x 80-inch flippable designs with foam layers and an innerspring core.

Pocket-Coil Mattresses

Premium Avenger and Odyssey mattresses use individually wrapped coils instead of a basic foam-only core. Avenger mattresses include edge-to-edge pocketed coils, firmer coils around the outer edge, and a breathable pillow top. The 42 x 80-inch Avenger measures 12 inches thick and has a medium-firm feel. Odyssey mattresses pair high-density comfort foam with pocketed coils and reinforced edge support. Select Odyssey models also offer a plush side and a firm side, so you change the feel by flipping the mattress.

Choose the Right Mattress Size

Do not order a mattress by truck model alone. Sleeper layouts, bunk sizes, and factory configurations vary. Measure the usable bunk area from side to side and front to back. Then compare those measurements with the mattress size and application list. For example, our 35 x 79-inch gel foam mattress lists applications for several International 9200, 9400, 9900, and Volvo VNL configurations. The 38 x 75-inch version covers certain Kenworth T600, T660, T800, W900, Volvo VNL, and VT880 applications. The 42 x 80-inch size appears across a wider range of Peterbilt, Kenworth, Freightliner, International, Volvo, and Western Star sleeper applications. Exact fitment still matters. Check the individual product listing before you order.

Compare Comfort Features

Convoluted Foam: Raised foam sections promote airflow and give the mattress a softer, textured support surface. Memory Foam: Forms around your body and adds a softer comfort layer over the mattress base. Pocketed Coils: Each coil moves independently, helping spread weight across the mattress and reduce movement from one area to another. Reinforced Edges: Premium Avenger and Odyssey mattresses use firmer support around the outside of the mattress. This helps when you sit on the edge of the bunk to put on boots or get dressed. Reversible Comfort: Select Odyssey mattresses have a plush side and a firm side. Flip the mattress when you want a different feel.

Shop by Comfort Level

Budget: Convoluted gel foam mattresses give you straightforward replacement options in several common sleeper sizes. Mid-Range: Memory foam and thicker foam mattresses add more cushioning and layered construction without moving into premium coil pricing. Premium: Avenger and Odyssey mattresses add pocketed coils, stronger edge support, thicker construction, and more advanced comfort layers for drivers who spend a lot of nights in the sleeper.

Buy Toppers or a New Mattress?

A mattress topper works best when your current mattress still has a solid base but feels too firm or thin. A full replacement makes more sense when the mattress has deep sagging, flattened foam, damaged springs, weak edges, or no longer supports you evenly. Before opening a new mattress, double-check the bunk measurements and return restrictions. Bedding products often have stricter return rules once the packaging has been opened. If you are unsure which size or construction fits your sleeper, talk with the Parts Pro team before ordering. A few minutes spent checking dimensions and fitment is better than finding out the mattress is too wide after you get it into the cab.

Frequently Asked Questions About Mattresses

What size mattress do I need for my truck's sleeper berth?

Sleeper berth sizes vary by truck make and model, so it's important to measure the length, width, and height of your bunk area before ordering. Most semi-truck mattresses are available in standard sizes such as 28", 34", 42", and 48" widths, and common lengths like 75" or 80". Checking the manufacturer's size chart against your actual bunk dimensions will help ensure a proper fit.

What are semi-truck mattresses made of, and how does that affect comfort?

Truck mattresses are typically made from foam, memory foam, innerspring coils, or a combination of these materials. Foam and memory foam options tend to offer pressure relief and conform to your body, while innerspring or hybrid designs provide more traditional support and airflow. The right choice often comes down to personal sleep preference and how many hours you spend resting in your sleeper.

How thick should a mattress be for a truck sleeper?

Thickness generally ranges from around 4 inches up to 10 inches or more, depending on the style and materials used. Thicker mattresses can offer more cushioning and support, but you'll want to confirm there's enough vertical clearance in your sleeper cab before choosing a thicker option.

Will a new mattress fit my existing sleeper cab platform or storage compartments?

Most mattresses sold for semi-trucks are designed to fit standard sleeper platforms, but it's still a good idea to compare the product dimensions with your cab's specific layout, especially if your truck has built-in storage compartments or a non-standard bunk shape. When in doubt, measuring your current mattress or platform space before purchasing is the safest approach.

How do I clean and maintain a truck mattress to help it last longer?

Using a mattress cover or protector can help guard against spills, stains, and wear from daily use. Most mattress covers are removable and machine washable, while the mattress itself should be spot-cleaned according to the manufacturer's care instructions. Rotating the mattress periodically and keeping it dry can also help maintain its shape and support over time.
