What Size U-Haul Trailer Do You Need for a King Bed? An Expert Guide

A 5×8 U-Haul trailer is generally the recommended minimum size for safely transporting a king-size bed. However, consider additional space for other furniture, personal belongings, or if your king-size bed is accompanied by a large headboard or footboard.

Understanding the King Bed’s Dimensions

Before deciding on the perfect U-Haul trailer, it’s critical to understand the dimensions of a standard king-size bed. While “king-size” is a standard term, minor variations exist. Typically, a standard king mattress measures 76 inches wide and 80 inches long. This is a crucial starting point for your planning.

Measuring Your Mattress Accurately

Don’t rely solely on the manufacturer’s stated dimensions. Grab a measuring tape and carefully measure your mattress’s width, length, and thickness. This is especially important if you have an older or non-standard mattress. Also, remember to include the dimensions of the headboard and footboard, if applicable, as these will add to the overall space required in the trailer. Failing to account for these extensions can lead to frustrating surprises on moving day.

U-Haul Trailer Options: Size Matters

U-Haul offers a range of trailers, each with its own dimensions and weight capacity. Choosing the right one will ensure a safe and smooth move. The most common contenders for a king-size bed are the 5×8, 5×9, and 6×12 trailers.

Comparing Trailer Sizes

  • 5×8 U-Haul Trailer: This is the minimum recommended size. It offers interior dimensions of approximately 4’8″ wide, 7’11” long, and 4′ high. This is tight but usually sufficient for just the mattress, possibly with some additional soft items like bedding packed around it.

  • 5×9 U-Haul Trailer: Providing slightly more space, this trailer offers a bit more flexibility. If you’re packing a frame or bulky bedding alongside the mattress, this option might be more suitable.

  • 6×12 U-Haul Trailer: This is the largest and most spacious of the readily available U-Haul trailers. It provides ample room for the king-size bed, its frame, headboard, footboard, and potentially other bedroom furniture. It’s ideal for a more comprehensive move.

Important Considerations for Choosing a Trailer

Beyond the mattress dimensions, consider these factors:

  • Frame Components: King beds often come with frames, headboards, and footboards. These require additional space and can significantly impact your trailer choice. Disassembling the frame can save space, but you’ll need to pack the components securely.

  • Packing Materials: Budget space for blankets, furniture pads, or shrink wrap to protect your mattress and other items during transit. These materials add bulk.

  • Weight Capacity: Each U-Haul trailer has a maximum weight capacity. Exceeding this limit can be dangerous and illegal. The weight of your mattress, frame, and other belongings must be within the trailer’s specified limit.

  • Tow Vehicle: Ensure your tow vehicle is capable of handling the chosen trailer’s weight and size. Check your vehicle’s towing capacity in your owner’s manual.

Safe Loading and Securing Techniques

Once you’ve selected the appropriate trailer, loading and securing your king-size bed is crucial for safe transportation.

Protecting Your Mattress

Wrap your mattress in a protective cover or mattress bag to prevent dirt, dust, and damage. Use furniture pads or blankets to cushion the mattress and prevent scratches.

Loading Techniques

  • Strategic Placement: Position the mattress in the trailer in a way that distributes the weight evenly. If possible, place it against the front wall of the trailer for added stability.

  • Securing Straps: Use heavy-duty ratchet straps to secure the mattress to the trailer walls. Ensure the straps are tight and evenly distributed to prevent shifting during transit.

  • Filler Materials: Use soft items like blankets and pillows to fill any gaps around the mattress. This will prevent it from moving around and minimize the risk of damage.

Distributing Weight Evenly

Uneven weight distribution can make the trailer unstable and difficult to control. Position heavier items towards the front of the trailer and distribute the weight as evenly as possible from side to side. This will help maintain stability and prevent swaying.

Frequently Asked Questions (FAQs)

Here are some frequently asked questions to further clarify the process of choosing the right U-Haul trailer for your king-size bed:

  1. Can I fit a king-size mattress in a U-Haul van?
    While theoretically possible in some larger vans, it’s not recommended. U-Haul vans often lack sufficient length and height for a king mattress. A trailer offers greater security and ease of loading.

  2. What if I also need to move a box spring?
    If you’re moving the box spring along with the mattress, the 5×9 or 6×12 trailer is almost certainly necessary. The box spring adds significant bulk. Measure both the mattress and box spring together to ensure adequate space.

  3. Is it better to rent a larger trailer than I think I need?
    Generally, yes. Renting a slightly larger trailer provides a margin of error and makes loading easier. It also allows you to transport additional belongings in the same trip, saving time and money.

  4. Do I need to rent a U-Haul trailer cover?
    While not mandatory, a trailer cover provides added protection from the elements, especially rain or snow. If you’re moving during inclement weather, a cover is a worthwhile investment.

  5. How much does it cost to rent a U-Haul trailer?
    U-Haul trailer rental prices vary depending on the size of the trailer, the distance of your move, and the time of year. Check the U-Haul website or contact a local U-Haul dealer for specific pricing information.

  6. What kind of straps should I use to secure the mattress?
    Use heavy-duty ratchet straps with a high tensile strength rating. Avoid using bungee cords, as they are not strong enough to secure a heavy mattress.

  7. Can I stack furniture on top of the mattress in the trailer?
    It’s generally not recommended to stack furniture on top of the mattress, as this can damage both the furniture and the mattress. If necessary, use padding to protect the mattress and distribute the weight evenly.

  8. What if my king bed is a California king?
    California king mattresses are longer and narrower than standard king mattresses (72 inches wide and 84 inches long). A 5×8 might still be too snug. Double-check the internal dimensions of your chosen trailer and consider the 5×9 or 6×12 for a more comfortable fit.

  9. Do U-Haul trailers have tie-down points?
    Yes, most U-Haul trailers have tie-down points strategically located along the walls and floor. These tie-down points are essential for securing your mattress and other belongings.

  10. Should I disconnect the mattress and box spring?
    Disconnecting them can save a little vertical space, but it will necessitate you to use straps to tie each item down separately. Ultimately, it is a personal decision based on your overall packing strategy.

  11. What is the best way to load the trailer?
    The best approach is to place the heaviest items, including the king mattress, at the front of the trailer, closest to the tow vehicle. This promotes better weight distribution and stability. Use furniture blankets or padding to protect against scratches.

  12. Are there any special driving precautions I should take when towing a trailer?
    Yes. Drive slower than usual, increase your following distance, and avoid sudden braking or sharp turns. Be aware of the trailer’s extra length and width when maneuvering in tight spaces. Practice backing up with the trailer in an open area before your moving day.
