The Best Car Adult Booster Seat You Can Buy in 2022

$ — WAOAW Seat Cushion ~ 1.46lbs

This is one high-quality adult booster seat made of memory foam. It's multi-purpose and has an ergonomic design, so it's genuinely comfortable and durable.

It's only made in one size, though.

$ — Car Driving Seat Cushion ~ 2.1lbs

If you could use the extra height while driving, this is the model for you. This super-thick, ergonomically designed cushion was exclusively made for petite people to lift them up while driving.

But it's not suitable for taller people.

$$ — Coccyx Seat Cushion and Lumbar Support ~ 3.69 lbs

Here we have an excellent two-piece model that offers lumbar support as well. It's soft and ergonomically designed, perfect for a car but also for chairs.

It doesn't help with conditions like discus hernia, though.

$$ — bonmedico Booster Seat ~ 2.18 lbs

If you don't find the U-shape the most comfortable for you, this is the model to consider. It's simple yet ergonomically designed and includes super-thick foam.

However, it is not the softest model out there.

$ — FORTEM Chair Cushion ~ 1.5 lbs

Here we have one fantastic set that has the best quality per price ratio I've seen. It features high-quality memory foam and breathable mesh. You get the booster seat and lumbar support, and a one-year warranty.

The only negative aspect is that it stains leather upholstery.

$ — WSGJHB Car Booster Seat ~ 2.07lbs

This is another adult booster seat for petite individuals. It's filled with cotton. Thus it's softer than regular foam but retains its shape and thickness over time.

Yet, some people find it uncomfortable.

$ — CarQiWireless Car Coccyx Seat Cushion Pad ~ 1.74lbs

Another model that will help you avoid the U-shaped design is here. Take a look at this unusual model. It's ergonomically shaped, breathable, and supposedly great for lower back pain.

Yet, if you prefer thicker models, this one is not for you.

#1. WAOAW Seat Cushion - Excellent Quality Memory Foam

Although designed as a chair cushion, this multi-purpose booster seat cushion can be used for the car seat, airplane seat, office chair, home chair, etc. There are really no limits.

It features an ergonomic U-shape that's ideal for long sitting hours because it removes the pressure from the coccyx and tailbone, thus reducing the pain in your back and promoting a healthy posture.

Now, what makes this cushion different from other car booster seats is the memory foam.

High-quality memory foam is not just soft, but it also conforms to your body and goes back to the original shape when you get up.

But not just that; memory foam is protected with two layers of lining to prevent the foam from wearing out and also keeping the germs and bacteria away.

The cover is made of velvet, and the good news is that you can simply unzip it and throw it into a washing machine to wash it and keep it clean.

Another convenient feature is that it has a non-slip bottom; therefore, it stays in place and doesn't interfere with your driving.

It's also fairly portable because of its small size and side handle for convenient carrying.

With more than six thousand reviews on Amazon, this adult booster seat has earned my trust, and since the reviews are nothing but positive, I recommend it to every driver in need.

#2. Car Driving Seat Cushion - The Best Booster Seat for Petite Adults

I'm not sure how to describe this adult booster seat because it's not really the most standard model.

It was originally designed for petite people in order to lift them up in a car seat and help them maintain the optimal height for driving.

That being said, this cushion is fairly thick.

It measures 15.75 inches in length, 15.75 in width, and 4.72 inches in height.

Basically, it can be of help if you need the extra lift in your car seat, but it can also improve posture and back pain because of its soft design.

Now, the adult booster seat is filled with PP cotton that doesn't flatten easily, yet it's fairly breathable, so if you're driving for extended periods, you won't be too hot in the car seat.

The manufacturer recommends this adult booster seat for lower back pain, sciatica, tailbone pain relief, and general discomfort while driving.

It has a non-slip bottom, too, so it stays in place throughout the entire ride, and the surface has a wavy shape to prevent you from sliding off the seat.

Now, the problem with this cushion is that it was designed for petite people, so one size doesn't fit all.

Also, it's pretty thick, so for some people, it is too high, so I would only recommend it for short people who need the extra height while driving.

#3. Coccyx Seat Cushion and Lumbar Support - Excellent Two-Piece Model with Lumbar Support

Here we have something a bit different from the previous two models.

This is a two-piece adult booster seat cushion. It can be used for an office chair, home chair, or a car, and it's specifically built for sciatica.

The seat is ergonomically shaped and reminds me a lot of the WAOWAW cushion I reviewed.

And then, the lumbar cushion is semicircular, designed to conform to your spine and promote a correct posture.

Now, this booster seat cushion is filled with memory foam, long-lasting memory foam, mind you. And it has a velour cover that is removable and machine-washable.

It is very important for your car seat cushion to have a removable cover because they get dirty, trust me.

The lumbar pillow has a mesh part that's added for extra breathability, and it prevents you from sweating excessively but provides more comfort with that air circulation.

There are two straps with buckles at the back of this cushion, so it's pretty straightforward to attach it.

Most people are satisfied with the overall quality and durability of this booster seat, but I noticed that people with herniated discs claim it doesn't help with their lower back pain at all. 

So if you have similar issues, pass on this one.

#4. bonmedico Booster Seat - Slightly Harder Foam

Here we have one super-thick adult booster seat from bonmedico, designed to relieve the lower back pain and help you improve posture.

It has high ratings, but it also has a couple of weak points, though.

So, this cushion measures 15 inches at length, 15 inches at width, and 5.5 inches in height. So far, it is the thickest cushion I have found.

It's filled with high-quality foam, but it's not memory foam, so I'm not entirely sure how exactly soft it is.

In fact, I've seen a couple of comments saying that it doesn't conform to the body shape that well, and it's too hard.

So, if you like sitting on softer surfaces, look at some other models we selected.

The cover is made of velour, and it's removable and machine-washable. You can keep it fresh and sanitized over time.

The bottom surface is covered in nods that create an anti-slip surface, so you can also use it on office chairs, benches, basically any surface where you need support and added comfort.

Another great detail is the side handle, added for more convenience while carrying, so this cushion is super-portable.

They say it features an ergonomic shape, but it's not the U-shape we're used to, but a classic wavy shape.

#5. FORTEM Chair Cushion - Fantastic Quality for the Price

Here we have another two-piece adult booster seat that portrays amazing quality for the price.

It comes at the price of the regular seat cushion, but it includes lumbar support as well, and it's made of 100% memory foam.

What I like about this cushion set is that it comes with breathable mesh covers.

Mesh is my favorite material when it comes to chairs and car seats. It doesn't make me sweat excessively, and it's more pleasant on the skin than velour.

Still, you can also remove the covers and wash them in a washing machine to refresh them.

Now, the bottom cushion features an ergonomic U-shaped design, and it's three inches thick. To me, this is the ideal average thickness for people of different heights.

There are adjustable straps with high-quality buckles that help you find the perfect position for the lumbar support.

According to the manufacturer, these adult booster seats bring pain relief to people who suffer from back pain, sciatica, tailbone pain, lower back pain, etc.

And due to its multi-purpose design, you can use it in your car, but also for your office chair and home chair.

Due to the non-slip rubber bottom, it won't slide off the chair, and the contours on the surface prevent you from slipping off.

On top of everything, this seat comes with a one-year warranty, and it has around nine thousand Amazon reviewers, of which 80% are five and four stars.

#6. WSGJHB Car Booster Seat - Cotton-filled Adult Booster for Petite People

Here we have an alternative to the adult booster seat for petite people that I reviewed.

It's pretty much the same, even the thickness of the cushion is identical, but the materials are different.

Namely, this cushion includes 20% down cotton and 80% 7D cotton, so it's softer than the other model for petite people that I reviewed.

Also, it won't deform easily, but it will retain the same shape over time.

Another great detail about this model is that it includes a three-layer composite fabric; therefore, the filling stays protected; hence it won't wear off easily.

Also, you can effortlessly unzip the cover and wash it to refresh the cushion.

As for the portability, the booster seat is very easy, and it includes a carrying handle, so it's pretty portable.

What is more, due to its anti-slip design, you can put it on different chairs and surfaces, and it won't slip away, so it's a perfect multi-purpose companion.

Now, this adult booster seat is supposedly ergonomically designed, but I'm not sure about that.

It features a standard cushion design, so I'm not quite sure that it leads to pain relief, but If you need some extra height while driving, then go for it.

As for the negative sides, people complain that it doesn't conform to the body shape as memory foam cushions do, but given the primary purpose of this booster seat, it shouldn't.

#7. CarQiWireless Car Coccyx Seat Cushion Pad - The Best budget-friendly Model

This model is slightly different from all the models I have reviewed thus far. It doesn't have the standard U-shaped design and isn't as thick as other models.

Personally, it reminds me of those gel-based cushions for pain relief.

What the manufacturer claims is that the ergonomic design of their adult booster seat helps with tailbone pain, lower back pain, sciatica, and general discomfort that appears after a long day sitting.

Now, the cushion has a non-slip bottom but also a fixating strap, so you can secure it to the car seat or any chair you'd like to upgrade.

It's filled with memory foam and breathable mesh on top; therefore, it's very comfortable and pleasant on the skin.

The cover includes a zipper, so it's a matter of seconds before you take off the cover, wash it and make it as good as new.

One significant advantage of this model is the price.

Namely, it is the most budget-friendly adult booster seat I found, and it has pretty high ratings.

Overall, customers are fairly satisfied with this adult booster seat, it's only on the rise, but for now, comments are predominantly positive.

As I presumed, the negative comments are mainly about the thickness of the cushion since it definitely is a thinner model.

Can I use a booster seat as an adult?

Yes! Adult booster car seats are pretty common among professional drivers and generally people who spend a lot of time on the road.

Of course, they are not as complex as booster seats for kids, and they are not tested in car crashes, but they are great pelvic support, and they can even help with back pain relief.

Based on your height and preferences, you can find these cushions with different contours, filling, and thicknesses, so I'm sure you will be able to use some model of all that are currently available on the market.

Are there car booster seats for adults?

There are. In fact, there are many different kinds of adult booster seats.

You can find them in U-shape, like the Waoaw model I reviewed, with a lumbar cushion like the Fortem seat cushion, or as a simple wavy cushion like the bonmedico model.

How do short people adjust car seats?

Besides the usual adjustments that your car seat has if you're a petite individual, there are some additional cushions you can buy to make the car seat more comfortable for you.

Namely, there are extra-thick cushions specifically made for short people to provide that extra lift needed for a better view of the road.

These cushions are not as soft as other adult booster seats, though, because they are made to retain thickness and integrity.
