You’re planning a truck bed camping trip and need to sleep comfortably. Figuring out what size air mattress fits in a truck bed is the first step to a great night under the stars.
It’s not as simple as grabbing any old air mattress. Truck beds come in many sizes, and so do mattresses. This guide will walk you through everything you need to know. You’ll learn how to measure, choose the right mattress, and make sure it stays put all night.
What Size Air Mattress Fits In A Truck Bed
The perfect air mattress size depends entirely on your specific truck bed’s dimensions. There is no universal answer. The key is to match the mattress length and width to your bed’s interior floor space, accounting for wheel wells and bed shape.
Most standard truck beds fall into short, standard, and long categories. Your mattress needs to fit within the flat floor area, not the total bed length which includes the walls.
Standard Truck Bed Sizes and Mattress Matches
Here’s a breakdown of common truck bed sizes and the air mattress dimensions that typically fit. Always verify your own truck’s measurements first.
- Short Bed (Approx. 5.5 feet / 66 inches): Often found on newer crew cab models. A full-size mattress (75″ x 54″) will be too long. Look for a shorter “truck bed air mattress” specifically designed for 5.5′ beds, usually around 70″ long. A twin (75″ x 38″) may curl at the ends.
- Standard Bed (Approx. 6.5 feet / 78 inches): This is a common size. A standard twin (75″ x 38″) or full (75″ x 54″) mattress will usually fit well in length. Width is your main concern here, especially with wheel wells.
- Long Bed (Approx. 8 feet / 96 inches): A full or even queen-size mattress (80″ x 60″) can fit in length. The width between wheel wells becomes the critical limiting factor for larger sizes.
How to Measure Your Truck Bed for a Perfect Fit
Grab a tape measure and follow these steps. It’s the only way to be sure.
- Clear the Bed: Remove all cargo, mats, and debris.
- Measure Length: Measure from the inside of the bulkhead (front wall) to the inside of the tailgate. Do this along the bed floor.
- Measure Width: Measure the widest part of the floor between the inner sidewalls.
- Measure Wheel Well Width: This is crucial. Measure the distance between the inner edges of the wheel wells. This is the maximum width for any mattress that will lie completely flat.
- Note Obstructions: Look for any built-in storage boxes, tie-downs, or bed liners that might protrude.
Types of Air Mattresses for Truck Beds
Not all air mattresses are created equal. Some are much better suited for the unique environment of a truck bed.
- Dedicated Truck Bed Air Mattresses: These are shaped to fit common bed sizes, often with cut-outs or contours to fit around wheel wells. They provide the most seamless fit and often come with integrated pumps.
- Standard Rectangular Air Mattresses: A standard twin or full can work if the dimensions align. You’ll need to ensure it fits within the wheel well width. A full-size mattress often bridges the wells, creating an uneven surface.
- Self-Inflating Sleep Pads: These are thicker, more durable pads. They offer great insulation and can be combined to create a custom sleeping surface. They’re less bulky but may not provide the same plush feel.
- Air Mattress with a Battery Pump: Essential for remote camping. Ensure the pump is compatible with your truck’s 12V outlet or bring a portable power bank.
Key Features to Look For
When shopping, prioritize these features for comfort and durability.
- Material Thickness (Gauge): A lower gauge number means thicker, more puncture-resistant material. Look for 18-40 gauge for truck use.
- Built-in or External Pump: Built-in pumps are convenient but can be harder to repair. External pumps offer flexibility.
- Insulation (R-Value): Truck beds get cold. An insulated or “double-height” mattress provides a barrier against the cold metal bed floor.
- Non-Slip Bottom: This is critical. A textured or grippy bottom prevents the mattress from sliding around when you move.
- Repair Kit: Always choose a mattress that includes a patch kit. It’s a lifesaver.
Step-by-Step Setup for a Secure Sleep
Setting it up right makes all the difference. Here’s how to do it.
- Clean the Bed: Sweep out all dirt, pebbles, and debris that could cause a puncture.
- Add a Protective Base: Lay down a moving blanket, a piece of cardboard, or a tarp. This adds an extra layer of protection.
- Unroll and Position: Place the deflated mattress in the bed, centering it as needed.
- Inflate: Connect the pump and inflate to the recommended firmness. Slightly under-inflating can help it conform to the bed shape.
- Secure It: Use bungee cords or straps hooked to the bed’s tie-downs to prevent movement. You can also tuck a sleeping bag around it for friction.
- Add Bedding: Use your sleeping bag, blankets, and pillows as normal.
Common Problems and Simple Solutions
Even with planning, you might encounter a few hiccups. Here’s how to fix them.
- Mattress Slides Around: Use a non-slip rug pad underneath. Or, create anchor points with bungee cords hooked to the bed’s tie-downs.
- Cold Air from Below: Place a reflective sun shade or closed-cell foam pad under the air mattress for insulation. Your sleeping bag’s rating is less effective when compressed from below.
- Wheel Well Hump: If your mattress bridges the wells, fill the gaps with folded blankets or foam blocks to create a level surface.
- Morning Deflation: Some loss is normal due to temperature drop and body weight. Top it off with the pump in the morning. If it’s major, check for leaks with soapy water.
Alternatives to a Traditional Air Mattress
An air mattress isn’t your only option. Consider these alternatives.
- Custom Foam Pad: You can have a foam slab cut to the exact dimensions of your truck bed floor. It’s permanent, warm, and comfortable, but bulky to store.
- Folding Camp Cot: A cot designed for truck beds lifts you off the floor, providing storage underneath and excellent insulation. It can be more expensive though.
- Camping Mattress Topper: A 3-4 inch foam topper can be rolled out. Pair it with a sleeping pad for extra comfort. It’s simpler but may not be as cushioned.
FAQs About Truck Bed Air Mattresses
Q: Can I use a regular air mattress in my truck bed?
A: You can, but it must fit within your bed’s specific dimensions, especially the width between wheel wells. A regular mattress may not have a non-slip bottom, which is important for safety.
Q: How do I stop my air mattress from moving in the truck?
A: Use a mattress with a non-slip bottom, put a rug gripper pad underneath, or secure it with bungee cords attached to the truck’s tie-down points. These methods work really well.
Q: Is a truck bed air mattress warmer than a regular one?
A: Often, yes. Many are designed with double layers or insulated materials to combat the cold conduction from the metal truck bed. Always add insulation underneath for the best results.
Q: What is the best air mattress for a 5.5 foot truck bed?
A: Look for a mattress specifically marketed for short or 5.5′ truck beds. These are typically around 70 inches long to fit without being crammed. Standard twins are usually to long.
Q: Can two people sleep on a truck bed air mattress?
A: It depends on your truck bed width. A full-size mattress can fit two people in a 6.5′ or 8′ bed if it fits between the wheel wells. Otherwise, two twin mattresses might be a better solution.
Q: How do I patch a hole in my truck air mattress?
A: Use the included patch kit. Dry the area, apply the adhesive, place the patch, and apply pressure. Let it cure fully before reinflating. A vinyl repair kit from an auto store also works good.
Final Tips for a Great Night’s Sleep
Choosing the right air mattress turns your truck into a comfortable camper. Remember to always measure your bed first. Prioritize a non-slip bottom and good insulation. And don’t forget to secure the mattress so it doesn’t shift during the night.
With the right preparation, you’ll wake up refreshed and ready for adventure. Your truck bed can be a surprisingly cozy place to sleep, offering a unique way to experience the outdoors. Just take your time to find the perfect fit.
