Moving mattresses can be a tough job, and most of you may think you need to rent a U-Haul to get the job done, but even the humble Toyota Prius has some surprising capacity when it comes to carrying bulky loads.

However, if you check the dimensions of a queen-size mattress, they exceed the dimensions of the Prius! Is it possible to maneuver a queen mattress into the rear of a Prius and make it fit?

As with most things where there is a will, there is a way, but short of trimming the mattress, it may seem impossible to make a quart fit into a pint pot. However, the queen mattress out of its delivery box has some flexibility, and keep in mind there is always adjustment of the front seats.

In this article, we investigate if a queen-size mattress will fit into the back of a Prius despite its larger dimensions than the available space in the car. We answer frequently asked questions to provide you with relevant information.

Let's get into it.

How do you put a queen-size mattress in the back of a Prius?

It can be done with manipulation and maneuvering the mattress while making some adjustments to the interior of the car. But here is the dilemma you will be initially faced with. Standard queen-size mattresses measure 60 inches wide by 80 inches long, making them roughly 5 feet broad by 6.6 feet long.

Additionally, the Prius's cargo area is around 5.5 feet long and 5 feet broad. In light of this, a queen-size mattress cannot fit in the cargo area when you look at the dimensions. Here are some tips to fit your queen-size mattress in the back of a Prius:

You will need.

Mattress cover.

Ratchets straps or rope.

Dolly truck.

  • Assuming you are moving your mattress from one home to another in the back of the Prius, you will need to fold the mattress in half across its shortest dimensions.
  • Before folding, place the mattress inside a decent mattress protector to protect the mattress from scuff marks and marks that may be difficult to remove from sliding the mattress around on the floor and in the rear cargo space of the Prius.
  • Once the mattress is folded, use two ratchet straps to pull the mattress together and reduce the overall volume the mattress will take inside the cargo space in the Prius.
  • If the mattress is in the bedroom, use a rope to tie the mattress. The rope may help you maneuver the mattress down a staircase.
  • Navigate the staircase, place the mattress on the dolly, and wheel it to the car.
  • Get assistance.
  • Ensure the back of the Prius is free from the clutter typically found in most cars' trunks.
  • Flatten the 60/40 split rear seats so they are lying flat.
  • You know the mattress is 5 inches too long for the Prius, but that dimension is made when the driver's and passenger seats are pushed back to the flattened rear seats.
  • Move both front seats forward by at least 5 inches. Depending on how compressed the mattress is, you may be able to maneuver it so it uses the extra space given by the passenger seat. If this is not possible, you will have to drive the car with 5 inches of less leg room.
  • When closing the hatch, ensure the mattress does not touch the rear window. If you slam the hatch, the window could pop out!

With a little muscle power and cognitive agility, you should be able to fit a queen mattress in a Prius without too many difficulties. In most cases, it is a two-person job, not because of the weight of the mattress but because maneuvering a bulky object can be cumbersome if you are alone.

Does folding a queen mattress cause damage?

For transporting purposes folding a mattress is ok. The manufacturer will recommend it transported flat, but that's unrealistic even for moving companies, so fold the mattress and when you arrive at the destination, unload the mattress into the bedroom, unfold and lay it flat.

Leaving a mattress folded for extended periods of time could cause damage, so if your mattress is going into storage, lay it flat if possible.

Is it legal to drive with a mattress in a car?

There is little information regarding the transportation of mattresses inside a car. But if you can tie a mattress to the roof and remain legal, having a mattress inside your Prius should be okay.

Regardless of the laws of the state, you will be traveling through common sense has to prevail in this situation. Your car should be safe to drive. If you have long legs and you can't operate the gas pedal and the brake properly, then you are unquestionably infringing on some traffic laws.

Your movements should not be impeded in any way, and you should be able to use the interior mirror or door mirrors and demonstrate that the car is safe to drive if pulled over.

Here are some pointers to help you drive safely while transporting a mattress in a Prius.

  • Ensure the mattress is securely tied down and can't move in the event of emergency braking or evasive maneuvering.
  • Stay off the highways if possible. It is going to add to your journey time, but you will be more likely to attract attention to your vehicle if on the highway.
  • Make sure you can operate the vehicle in accordance with the laws, you can see your mirrors, and the mattress does not obstruct you.
