Love the Mammoth!
July 28, 2023
This is not our first Clek, but it is our first Fllo! We have had several Foonfs, but I decided to try the Fllo this time. First of all, I have to mention the Mammoth color way. The wool is incredibly soft, not scratchy at all. It feels very luxe, and I know it provides great temperature regulation whether it’s cold or hot. Now, we needed this seat for a child who is already forward facing so I chose the Fllo since we wouldn’t need the rear facing base. We use the seatbelt to install and it is secure and easy. Overall, I am completely satisfied with this seat.

Mostly great, minor complaints are no big deal

This car seat has served us very well. I love that it has a solid frame and if free of flame retardants. It is a nice sleek and slim model. I wish it had come with cup holders, though I know they can be purchased separately. I also wish it was lighter and easier to install. The steel frame adds to its weight, but perhaps there are other options. Aluminum?

I was originally worried about the durability of the jersey fabric, but one year it its still looking great! This is a pretty serious carseat, but we ultimately chose it because it fit perfectly in the back of our VW Golf. Kids seem very comfortable in it, and I love the look as well.

Love this car seat design, slim and comfortable. Does take up a bit of space rear facing but I think all car seats do. I will say I prefer the 100% merino fabric on the older model I have that one for my older son.

Wouldn’t purchase again
March 7, 2023
We didn’t like these car seats at all. When we installed it was obvious that putting baby rear facing was going to be a squeeze just putting her in the seat. Then my front facing child was able to slip out of the chest straps because they are so difficult to tighten. The clips felt like inexpensive material and were difficult to use.

My kids loved it
February 8, 2023
I bought two of these over the years for my kids. I like the quality and safety standards of Clek car seats. My only gripe was that the crotch strap design makes it a bit hard to strap the harness. I eventually got really good at it and it didn't bother me anymore. Also, this seat is HEAVY. If you are going to move it often between cars, it may not be a good option.

Great middle seat car seat
September 27, 2022
This is a niche seat. I am happy with my purchase. I followed "the car seat lady blog" suggestion for a car seat to place in the middle. I cross referenced it with ratings on consumer reports. This seat is quite pricey - roughly double the price of the four $150-250 car seats I bought before. The selling point of this seat is the locking thread path for a seat belt. The seat looks comfortable and is narrow, but safe. The configuration of this seat allowed me to place an adult in the back seat next to two car seats in the rear. It is a win. I chose the knit fabric reasoning that a major poop/vomit storm happens once a year with a toddler and you'd have to wash the fabric at that point anyway. The rest I can vacuum away with or without fancy fabric. The seat sits high which is a plus for a toddler, who wants to see more. But once you adjust the head rest, it quickly shows in the rear view mirror.

High safety and non toxic

Low profile but with high safety ratings! This is a great seat. We got it for my folks to drive around the grand babies and we have the foonf. Honestly this is easier to install, remove than ours. I love that the merino wool is flame retardant free. I wish they would do all their seats FRF. 5 starts

So far so good!
September 9, 2022
We've been using the Fllo for about 5 months and it's worked great! It is definitely wider from front to back but that provides our tall girl with plenty of leg room. It can be a bit difficult to install and I don't look forward to when we have to move the head rest up.

We mainly chose this car seat because of my husband's Ford Explorer has the inflatable seat belts in the back seat and this was one of only a few car seats that would work with them.

So far happy with our choice!

Love this car seat. Installation was easy, a few more steps than our click in and out infant seat, but nothing complicated and directions are easy to follow. Car seat is very well made and sturdy. Fabric is very easy to clean, I just wet a hand towel and wipe it down and everything comes off.

Very safe but quite complicated to install
July 21, 2022
The amazing safety ratings on these car seats are what sold me on them. The space-saving narrow seat was a great bonus.

The issue is that they are heavy and difficult to install. My husband is the only one who can lift them, so he installed them every time and nearly lost his mind with frustration. The user’s manual is 93 pages of dense reading, so it’s not easy to troubleshoot if you run into and issue. Alarmingly, one of the straps for forward facing was detached on one of the seats and it doesn’t seem possible to reattach it. The folks at Clek sent us a new strap, which in no way solved the problem.

After two years of using them, finally replaced them with Nuna seats and couldn’t be happier.
  • Incredibly safe and thoroughly tested by a team of engineers. Narrow width makes it easy to put three car seats in one row or squeeze an small adult between two of them.
Best Uses
  • Only buy them if you plan to install them once and never take them out again.
  • Incredibly heavy and impossible for a small person to lift.
  • Very, very difficult to install and probably best to have an engineering degree to do so.

Great Nontoxic Car Seat
July 11, 2022
The most important things for us with car seats are safety and non-toxic, no flame retardants or stain repellents or any other chemicals and natural fabric (not polyester). This is the best seat available on the market that meets all these requirements. Wish it wasn't so extremely expensive but glad it can last 9 years. Also nice it is made in Canada.

Hands down best seat!

One of the best seats on the market! So easy to install, great long life span. I had kids from ages 3 months-9 years old be comfortable in this seat. Long rear facing option with an anti-rebound bar. So many pluses for this seat!

Love these seats!
May 5, 2022
We love these seats! They have such a long life span. My youngest used it beginning at 3 months old with an infant insert and it fit her so much nicer than other infant seats. My oldest are almost 9 and have just reached the hight requirement. We also love that it allows for extended rear facing which was a must. The anti rebound bar gave me an additional peace of mind in the event of a crash. Another huge bonus is how slender the seat is. It allowed us to sit 3 across in both our Honda Odyssey and Honda Pilot. Super easy to install! The only concern is that it slid a bit on my leather seats so it was difficult to get a tight instal right away, but this seat allows for a thin towel underneath which fixed the issue right away!

April 30, 2022
We were originally sent the wrong seat, but Albeebaby corrected it and sent the right one immediately when I notified them. It was a quick easy process. As far as the Clek goes it makes fitting 3 across a breeze and the mammoth fabric is a big plus for me.

Good narrow seat, but a few issues
April 28, 2022
Pros to this seat: it is quite narrow and I think overall comfortable for our toddler. It provides a lot of rear facing leg room and so even at 21 months, my ~70th percentile son isn’t looking remotely cramped rear facing.

Cons: the crotch strap must be on the inner slot when rear facing and even on the longest setting, the strap is short. This is already proving to be a fit and comfort issue for my son. I don’t know why the strap is so short. The harness straps also dig into his neck sometimes, leaving marks, with the shoulder pads or without.

Install was ok. Not as easy as the Nuna Rava we have in our other car, but not awful.

Overall I like the seat but prefer the Nuna Rava.

I was searching for a long time for a car seat that was non toxic and this one is so great! I love the minimal design, and it doesn’t take up quite as much room as other car seats I’ve seen (which is a huge plus if you have a mid size sedan like me).

This product was as described and we got a great deal! I was nervous about buying a car seat at such a discount, but it was manufactured the same year we bought it, so we got a quality product! It shipped as stated and we got up to date notifications as it was delivered. Would definitely buy another bigger ticket item from Albee again!

Quality but Heavy
February 7, 2022
The car seat is generally good, and I bought it for the great cash test figures. But the car seat is on the heavy side and the fact that it doesn't have a removable and washable cover knocks off a star.

As a mom of 6 kids, I have had my fair share of car seats. We love our Clek Fllo. It’s simple, streamlined and looks great. So many baby items have so many accessories and features that just aren’t needed. My daughter is comfortable and I’m confident she is safe. Love all the fabric choices as well.

Safety, comfort, coolness, and compact!!
August 8, 2021
This carseat is very comfortable for my son, even on longer road trips or just down the street. He has plenty of room in the seat at just under 2 years the stretch out, folks his legs, or hang them over the side. His keck doesn't look even the tiniest bit stiff when he falls asleep. He looks very safe and comfortable napping.

The material is super soft, it will get dirty and cleans fairly easily. The cushions and headrest seems almost pillow-like which is very cozy during car naps. Plush, yet, the temperature seems to stay cool; even in the Texas summer heat.

The size is narrow, but I have a tiny back seat area in my volvo v60 and it is a bit large still. Any carseat takes up too much space in my vehicle and this carseat has been the most compact.

Overall, I make it work for the tight space and love everything else!! My son seems to love it as well!!

I feel like my baby is so safe
July 25, 2021
Let me just say I researched for weeks before deciding on this one. the only downfall is you can't wash the carseat cover but it has a eco friendly stain guard on it and def can be cleaned with a cloth. The baby loves it and just chills the whole time in the car seat. Such a difference from his infant. Let me tell you the seat is so secure it doesn't move at all if you shake it. Don't hesitate to buy. I feel like my baby is so safe in this seat.
