19 Votes

Rate this product

Seatbelt Sizer is an attachment that you can hook to virtually any ordinary seatbelt, and it'll extend that seatbelt's waist strap by nearly 10 inches. It's claimed that this extension will help make seatbelts more comfortable for plus-sized people, along with those suffering from aches and pains due to old age or injury. This seatbelt attachment is made of the same material that standard seatbelts are made of, and can be used in cars, trucks, and SUVs.

Total Cost Breakdown

The cost of Seatbelt Sizer is $19.99 plus $5.99 shipping. The special TV offer allows you to receive a second Seatbelt Sizer at the discounted price of only $5.99 for a total price of $31.97.

Price is from As Seen on TV Commercial page:

How to Use (Step by Step)

  1. Insert Into Seatbelt Lock

    To get started with your Seatbelt Sizer, insert the end of it that contains the silver metal tab into an ordinary seatbelt's lock. It doesn't matter if you'll be sitting in the driver's seat, the front passenger seat or the backseat— the attachment will work the same way in any of those places.

  2. Hook Other End To Arm Strap

    Next, hook the other end of your seatbelt attachment to your seatbelt's arm strap, as if you're putting your seatbelt on without the attachment. If you find that you don't need the whole extra 9.8 inches the attachment offers around the waist, you can then adjust the attachment to make it a bit smaller.

  3. Drive Away

    Once your seatbelt and its attachment have been fastened securely yet comfortably around your waist and upper body, you can drive away (or if you're a passenger, let the driver do that). If you no longer feel comfortable as you go through your first ride with your seatbelt attachment, you can always make it smaller or larger later.


  • Black

    Each Seatbelt Sizer comes in a shade of black, which means each one will look good in nearly any car, regardless of the color of the upholstery or any existing seatbelts.

  • Works In Many Vehicles

    You'll be able to use this seatbelt attachment in almost any vehicle under the sun, as long as it's a car, truck or SUV. Therefore, if you get a new vehicle or spend a lot of time driving a vehicle that belongs to someone else, you won't need to get a different seatbelt extender to use in it.

  • Compact

    The Seatbelt Sizer is small enough to fit in a large handbag, a backpack or a briefcase, if need be, which means you can carry it with you to use in a taxi. If you don't take taxis, its compact size may still come in handy, as you'll be able to carry this attachment with you when it comes time to ride in a friend or relative's car. Furthermore, if you ever need to store your attachment in your home, it won't take up much space in any room.

  • Seatbelt Handle Included

    A black seatbelt handle is included with each Seatbelt Sizer. Those people who are tired of having to twist and turn a great deal in order to grab the top of their seatbelt will be able to attach this handle to their belt. If you do so, you'll still have to reach out to grab your belt, but your reach won't be as far as it would be without the handle.

Positive Points

  • Ideal For Plus-Sized People

    Plus-size people may often find that the seatbelt that comes with their car isn't quite long enough to wrap around them. Instead of having to go without a seatbelt (unsafe and potentially illegal) or cramming themselves into one, a plus-size individual will be able to attach a Seatbelt Sizer to their belt to make it longer. This will make their ride in the car more comfortable since they'll no longer have to deal with a too-tight belt pushing into their stomach in a forceful way. If weight is lost, the option of removing the attachment will be available.

  • Promotes Less Aches and Pains

    Seniors with arthritis and people with injuries may not have difficulty fitting into a seatbelt, but they may have difficulty putting a tight one on, especially if their problems lie in their hands. A somewhat tight seatbelt may also bump against the area in which pain is experienced, and provoke more pain. Fortunately, if you're a person experiencing pain, you'll be able to attach a Seatbelt Sizer to your belt to lessen pressure on your body as you put your belt on and as you travel.

  • Will Fit Around Kids' Carseats

    Some standard seatbelts won't fit around a child's car seat, or once fastened, will be so tight that they push uncomfortably against a child's legs. Each Seatbelt Sizer will comfortably fit around most car seats, though, so once you've got one, you won't have to consider taking your child out of their safety seat for a more comfortable ride. If you care for more than one child and often have more than one car seat with you, you might consider getting more than one of these seatbelt-extending attachments.

  • Makes Vehicles Safer

    No matter who you are, if you get into a car accident, you'll be much safer if you're buckled into a seatbelt than if you're not, and the same goes for anyone in your vehicle. By making seatbelts less restrictive, the Seatbelt Sizer will increase the likelihood that you'll keep yours on and avoid damaging your body.

Negative Points

  • No Alternative Shades

    While the black shade that each of these attachments comes in will look attractive in the majority of cars, people who want to customize the shade of their seatbelt extender may be disappointed with black. It would be helpful if this seatbelt attachment could be made available in at least a few other shades commonly seen in cars, such as navy blue, gray and maroon.

Save Money

If you happen to get caught driving without a seatbelt since it doesn't fit properly or otherwise causes you discomfort, a police officer may subject you to a fine. Over time, if this occurs on a regular basis, you may begin racking up a lot of civil debt due to your refusal to wear a belt. Once you've got a Seatbelt Sizer, though, it's unlikely that you'll incur a fine, as your seatbelt will probably be fastened securely around your waist at all times, while still giving you breathing room.

Save Time

An alternative to obtaining one of these seatbelt attachments is replacing an entire seatbelt if it doesn't fit around you or fits way too tightly for comfort. This may take you anywhere from 15 minutes to a couple of hours, depending on your skill level. However, if you use a Seatbelt Sizer to extend your belt instead, you won't have to waste all that time removing an old seatbelt and installing a new one.
