Here we see little Freya in her car seat with a boatload of non-regulated products. She looks comfy, but this isn’t safe for our Little. As a general rule, products sold separately from your child restraint should not be used, due to the fact that these products may affect the safety of your restraint in a crash. Even a seemingly minor change to your restraint could alter the way is designed and tested to perform in a crash, resulting in serious injury or death. Many products have a label that says “Crash Tested!” and even add “to FMVSS standards” on the box or in the product manual, but this is a little misleading since there is nothing in FMVSS that covers these items; hence the term “non regulated”. There is no way to know how a mirror, harness pads, seat protector mat, or anything else that doesn’t come with the seat will change how it performs during a crash. There’s no crash test performance standard or benchmark for testing, so while companies do claim to test items like harness pads or inserts, we just don’t know what is being done, or how, and what the results of the tests were. We do know that any item which comes with your restraint or is approved for use by the manufacturer with your restraint has been tested with it, and so we know that they’re safe to use when used properly. There are, of course, gray areas and we wish to provide with the information you need to make an informed decision. Below we have listed some of the most common non regulated products, the concern the may pose, and our recommendations for safe alternatives when applicable.
Infant Support Inserts, Head Rests, Pillows, and other Comfort Items
Safety Concern: Many of the items in this category will affect harness placement, pushing the child out of safe position, and may change the distance and speed the head and chest travel in a crash, resulting in serious injury or death. They also have the potential to push a newborn or young infants head forward which can compromise the child’s airway. Only items sold with your restraint, or with the express written permission of the manufacturer, should be used with your restraint. Your manual will contain language to this effect.
Our Suggestion: In cases where no approved option is available, using tightly rolled receiving blankets alongside (not over the top) of your infant, clear of the harness, is a safe method to give additional support when needed. Below, we see Freya again, with rolled blankets on either side of her body to provide additional support. Freya is now safe and supported!
Shoulder Pads/Harness Covers
Safety Concern: After market shoulder strap pads or covers add bulk to the harness, often interfering with tightening the harness and proper chest clip placement. They may change the distance and speed the head and chest travel in a crash, resulting in serious injury or death. It seems harmless, but consider the fact that there are seats that come with strap covers that require them to be removed at a certain weight or stipulate they must not be removed because they affect the crash performance of the seat. The addition of non-approved shoulder pads provided with your restraint or with the express written permission of the manufacturer should be used. Your manual will contain language to this effect.
Our Suggestion: If your child experiences discomfort, pulling the shirt up between the harness and the child’s neck can often ease discomfort. Ensure you are not over tightening the harness straps and that the harness height is at an appropriate setting for your child. If narrow straps cause injury, you may need to explore the option of a different restraint. Be sure to read your restraint manual to see if the harness pads on your restraint can be removed or when they need to be removed. Occasionally, manufacturers will have approved strap covers that can be sent out, sometimes checking with the manufacturer will help. In the picture below, one can see that the harness is touching little Eibhlin’s neck on her left side. This can be uncomfortable for some kids. On her right side, where the red arrow is pointing, we see that her shirt collar is between the harness strap and her neck.
Weather Protection, Swaddlers, Bags and Caps
Safety Concern: Some of these products come between the back of the restraint and the child, which interferes with proper harness fit and introduces slack into the harness. Similar to head supports and shoulder pads, adding layers (besides street clothing) between your child and the restraint may change the distance and speed the head and chest travel in a crash, resulting in serious injury or death. Products that include a layer between the restraint and the child should not be used. Your manual will contain language to this effect.
Our Suggestion: Products such as the “shower cap” style of cover or a cover that hangs from the handle may be an option if you have concerns about keeping your child warm, but proceed with caution. Always ensure the cover does not affect the installation and proper fit of your restraint, and understand that any item added to your vehicle or restraint may have an effect on safety. The best option is to dress your child in appropriate, well fitted, warm, compressed layers, (such a single layer of fitted polar fleece) and covering him or her with a favorite blanket over the properly fitted harness.

Safety Concern: A seat protector comes between your vehicle seat and your child restraint. Some have a “grippy” texture or are very firm. These can disguise a loose install, or introduce slack into the belt if the protector shifts during a crash. It is best to never use anything between the vehicle seat and the child restraint. This is a firm seat protector mat that has a “grippy” surface, making it difficult or near impossible to install a restraint over it.
Our Suggestion: Damage to a vehicle seat from a properly used child restraint is rare. Dents in upholstery or leather pop out over time. If you are concerned about mess, a thin receiving blanket can keep your vehicle seat free of crumbs and spills. An old nursing cover or similar fabric, hung from the head restraint, but not coming between the child restraint and the seat back, can protect your vehicle seat back from muddy rear facing shoes. Of course, you could always limit food and beverage in the vehicle and remove shoes as well. If you feel you must have something to protect your seat, some manufacturers allow the use of their brand of seat protector to be used with their restraints. Usually, a thin towel or receiving blanket can also be used, if allowed by the manufacturer of the child restraint, provided it doesn’t interfere with the installation of the restraint or base. Check your manual or call your manufacturer to confirm what is allowed. We highly encourage you to check that it does not interfere with installation before you decide to use it. Install your seat with the pad in place, making sure there is less than one inch of movement at the belt path. If using LATCH, undo one side, remove the pad, reconnect the LATCH strap and check for movement. If using the vehicle belt, mark the latch plate position with chalk or use a locking clip to hold the belt, remove the pad, and buckle the belt. If you no longer have an acceptable install, discontinue use of the seat protector and try one of the options listed above. Check out our full article on seat protectors and car seats.
Safety Concern: Covers that were not made by the manufacturer and tested with your seat may interfere with harness fit and flammability. It may also change the distance and speed the head and chest travel in a crash, resulting in serious injury or death. Only covers provided by the manufacturer for your model of restraint should be used.
Our Suggestion: If your cover needs to be replaced due to wear, or damage, contact the manufacturer to purchase a replacement cover. Occasionally covers for restraints can be found second-hand; this may be an option for you as well. Look for the brand, and other required labeling, to ensure you are getting an approved option.
Vehicle Belt Tightening Devices
Safety Concern: Devices that tighten the vehicle safety belt have been shown to damage the vehicle belt, leaving it weakened or completely severed. They may also break or come undone in a crash causing unknown damage, injury or death. Only human strength should be used to tighten your belt. The product below is approved for use, but is known cause damage the vehicle belt. It isn’t necessary, and can pose a hazard.
Our Suggestion: If you are having difficulty getting a secure install, there are a variety of techniques to try, but these will vary depending on the restraint, vehicle, method of install and type of belt. We would love to help you troubleshoot. Visit our Facebook group, send us a message, or even better – find a CPST in your area, and we will help you get it snug. No seat requires super-human strength to install. Most of the time, working smarter, not harder, will help. Use leverage and pull the belt from another angle. Sometimes, pulling the seat cover back a little will help, because then you can pull the vehicle belt or lower anchor strap at a different angle.
Mirrors / Toys
Safety Concern: Anything in your vehicle can become a potential hazard during a crash. A mirror could break, or cause additional injury if it came loose from the headrest and became a projectile. Toys hanging from a seat (particularly the handle of a rear facing only seat) can hurt the child if they go flying into their face, or can pose a strangulation hazard if the attachment is long and flexible.
Our Suggestion: If you feel it is necessary to see your little one via a headrest mirror, perhaps due to a health issue, be aware of the risks involved before making your decision. Choose a mirror made of only soft, flexible materials that can be tethered to minimize these risks. Remember that a mirror can be a distraction hazard, so keep your eyes on the road and only check on your Little if you’re not the driver or if you’re at a complete stop in an appropriate and safe spot to do so. The same rule applies to toys – stick with items that are soft and lightweight.
Safety Concern: Products marketed to keep your seat safe from accidents and spills may interfere with proper harness fit.
Our Suggestion: It is best not to have anything between your child and his or her restraint, however we understand this is not always practical, especially when potty learning. A chux pad or prefold diaper are thin alternatives and can be used under a portion of the child’s bottom if necessary. If the manufacturer of your restraint offers a product for your seat, make certain it does not cause the crotch buckle to move or interfere with harness fit (you should be able to use it without adjusting the harness for your child).
What do manufacturers have to say about the use of non regulated products?
In your child restraint manual, the manufacturer will usually have very specific warnings or instructions about what you can use with your restraint. We’ve chosen several different restraints from different manufacturers and taken excerpts out of their manuals so you can see what their warnings include and where you might find it in the manual.
Here are examples of information found in various manuals regarding the use of non regulated products:

Each restraint’s manual may be different, and there also may be some differences between different versions of manuals for the same restraint because manuals are sometimes updated over time. Please consult your restraint manual for guidance. This blog post is not intended to replace reading your restraint manual. When in doubt, refer to your manual or contact the manufacturer.
