The One4Life® Slim all-in-one car seat takes your child from birth to big kid with trusted Britax safety, ClickTight® installation, and a slim SpaceSaver™ design. As a convertible and harness-2-booster seat in one, it grows with your child for 10 years. It starts rear-facing with an extended capacity of up to 50 lbs., so your child can ride rear-facing longer. It easily converts to forward-facing toddler mode (up to 65 lbs.) and high-back belt-positioning booster mode (up to 120 lbs.) when your child is ready. With a slim outside and spacious inside, the 17.5” seat is designed to fit 3 across* without compromising safety and comfort. ClickTight helps you install with confidence, every time. The base and shell are easy to wipe down for hassle-free cleanup. The car seat cover is safe to machine wash and dry, and it’s naturally flame-retardant with no added FR chemicals. One4Life Slim features a high-strength steel frame, a SafeCell® crumple zone, and a V-shaped tether. As your child grows, you can easily adjust the 15-position no-rethread harness and headrest with one hand. With cooling channels, premium padding, three infant inserts, and built-in armrests, your child will love every ride. *Britax cannot guarantee 3-across fitment in all vehicles.

Recommendation – Britax strongly recommends:

Children ride rear-facing to the highest weight or height specified

Children should remain in a child seat with a 5-point harness until reaching the maximum weight or height allowed

The top tether be used at ALL times when installing the child restraint forward-facing.

Such a great tool!
Size: 48" One Size Fits Most, Color: Black
I have had this product for a week, and I have nothing but good things to say about it! I debated for a couple of days as to whether or not to purchase it because the price seemed a tiny bit much for what looked like such a simple item. Now I know it’s that very same simplicity that makes this such an effective tool! Best money I could have spent on my dog! I’ve had my rescue Patterdale Terrier for a little under 3 months and I have quickly found out he is far from being perfect. It has taken a lot of time to begin working on correcting some of his problems, one at a time. Like many dogs, he also pulls when being walked. So what did I do as a regular person in need of quick dog tips? I searched up Cesar Millan videos on YouTube. 😂 I had purchased a Flexi leash two weeks after adopting my dog, and he broke it within another two weeks. While it was disappointing when I first found out, I now see it as a blessing in disguise. Paying close attention on YouTube, I noticed common features in all of the videos where the owners had pulling problems. Most owners in these videos had Flexi leashes, and the dog is always walking in front of the owner, not besides them. All Cesar uses to start making a change are leads just like this one. He never explicitly promotes his lead on his show, but after seeing the immediate increased control using such a simple tool, I decided to look online and found this. So I figured, why not? My dog is 28lbs, so he isn’t big enough to overpower and drag me during a walk. After the Flexi broke, I resorted to using a regular hook-through-the-collar leash. The pulling problem was still there, and would only get worst if we came across a squirrel. As soon as we started using this lead, he’s become much more responsive to my corrections. As soon as he is too far in front of me, even without actually pulling, I give it a quick, gentle tug and a “Chh!” and he‘s learned that he needs to slow down. If he actually pulls and won’t immediately respond to my correction, we’ll sometimes stop walking altogether until he sits, calms down, and realizes that we’ll only walk at my pace. This lead has helped tremendously and there’s rarely ever any tension on the lead when walking now. It’s hard to believe it has only been a week since I’ve started using it, and I don’t believe I’ll go back to using the traditional leash unless absolutely necessary. I would definitely purchase this again! And no, I have not been paid by anyone, nor was I sent this by any company to review it. Just a regular girl who is so happy to have found something that is actually seeming to work!

Worked from day 1
Size: 48" One Size Fits Most, Color: Black
This leash is the best thing I’ve ever bought for my dog. He’s 1 year and 4 months old, and I’ve bought at least five different harnesses since I got him, including very expensive ones like DogfriendlyCo. He pulls with every single one of them. I bought this leash a while ago, but I only used it once because I was afraid he would get hyperactive and choke himself. He hated it at first and tried really hard to get out of it. Today, after four months, I decided to give it another try and omg! This is the first time I’ve been able to walk him without feeling anxious or embarrassed. He walked by my side the whole time, and the leash stayed loose. Iwould only pull a little when he wanted to go ahead of me. I could tell he enjoyed the walk and so did I. I’ve tried it a couple more times just to make sure it wasn’t luck, but this thing really works. Highly recommend.

Only “tough” toy my Doberman loves!
Pattern Name: Octopus
Not indestructible, but last a good long while. Definitely worth the money and lasts longer than any other plush toys we’ve had (which is all my dog will play with). It’s for sure my Dobermans favorite, I’ve ordered probably 10 at this point. He gets the stuffing out after a month or two and we open a new one. He’s picky with toys, either destroys them or ignores them, but he never gets bored with his octopus! 🐙 He sneaks one outside once in a while and the neighbor’s dogs steal it. They love it too and thankfully can’t destroy before I retrieve it.

Great for a Pitball
Pattern Name: Octopus
I have a Pitbull and she absolutely loves this toy. I always wait a while before giving a review. She has had this toy Since the beginning of July and she is still playing with this toy. It does have little holes but it is still going. She loves it. Playing tug of war with her. I also take it and wrap it around her collar and watch her dance around trying to get it out(I don't leave it there long). This a great buy. I also bought and extra one so when this one does finally dies she will have another. The material is strong, The sound is about normal for a squeaky toy.

Fun Resilient Chew Toy
Pattern Name: Octopus
I have a boxer/pit mix and she loves this! I bought it 4 months ago and it’s still going strong so I know it’s quality made and perfect for dogs that like to chew and play tug of war. It has been chew resistant for my girl and she loves the little squeak. I just throw it in the washer when I wash her bed. Great value and a safe toy that’s a good size for a medium to large dog.
