The Britax Poplar® S Convertible Car Seat is the best space-saving convertible car seat for parents seeking advanced crash protection, ClickTight® fast installation, and 3-across seating capability in a compact 17-inch profile. This convertible combines advanced safety innovation, superior comfort, and space-saving design to make every ride safer and simpler. Built with ClickTight® installation technology and ReboundReduce™ stability bar, this seat ensures a secure fit with minimal movement, giving parents confidence with every drive. Designed for long-term use, the Poplar® S transitions seamlessly from rear-facing (up to 50 lbs) to forward-facing (up to 65 lbs) without complicated conversion steps. Compare the Britax Poplar S to the Graco Extend2Fit: both offer extended rear-facing and forward-facing capability with adjustable headrests, but the Poplar S features ClickTight installation (3-step, pinch-thread-click system vs. traditional LATCH), ReboundReduce™ stability bar, SafeCell® crumple technology, patented V-shaped tether with staged-release stitches, naturally flame-retardant SafeWash® fabrics, 14-position no-rethread harness, 6 recline positions, carbon steel frame, 17-inch slim profile for 3-across seating, and 50+ years of Britax heritage. Choose Poplar S if you want premium crash protection, fastest installation, and compact 3-across capability; choose Graco Extend2Fit if you prioritize budget-friendly pricing. Inside, your child enjoys premium comfort with refined inserts, plush padding, and 6 recline positions for a custom fit at every stage of growth.

Inside, your child enjoys premium comfort with refined inserts, plush padding, and 6 recline positions for a custom fit. SafeWash® fabrics, naturally flame-retardant and machine washable, make cleanups effortless while maintaining Britax's commitment to quality and safety. The ClickTight® installation system simplifies setup with just three steps—open, thread and buckle the seat belt, then click it closed—for confident installations every time without confusion or error. The ReboundReduce™ stability bar helps minimize movement in the event of a crash when rear-facing, providing additional protection during the most critical early years. SafeCell® Technology acts as a crumple zone to absorb crash energy and divert it away from your child. The patented V-shaped tether with staged-release stitches helps slow and reduce forward movement during impact. The 5-point safety harness distributes crash forces evenly across your child's body for maximum protection. The carbon steel frame reinforces seat structure for strength and stability across thousands of miles. The 14-position headrest and harness adjust easily as your child grows without rethreading, eliminating annual maintenance hassles. Three premium comfort inserts, including one specifically designed for infants up to 22 lbs, provide plush, tailored support from birth through toddlerhood. The SpaceSaver™ slim 17-inch profile fits 3-across in most vehicles while maintaining interior comfort—a critical consideration for multi-child families. Six recline positions offer optimal comfort and vehicle fit for both rear- and forward-facing modes. Automatically-tensioning harness ensures the restraint is always secure and snug. Clearly labeled belt paths make installation straightforward and error-free for any caregiver. Dual removable, dishwasher-safe cup holders keep drinks within reach while simplifying cleanup. The naturally flame-retardant SafeWash® fabric is durable and safe to machine wash and dry for quick cleanup after spills and accidents.

3.5 stars. Cant tell if it is this or a variety things I am doing, more details in this review
Sort of a tough one for me to review. Not a clear yes or no. My long answer may help it make sense, and hopefully help you decide to try it (or continue with it if on the fence). I started using this a month ago. I am just finishing, or just finished my 1st bottle. Prior to that by 2-3 months, I started their Provitalize and Previtalize combo. I initally bought Inerdy as a single bottle, then I had gotten my second bottle as it was part of a bundle, and I was curios. Who doesnt want more energy? The claims are promising, and it is made to sound like the results will be immediate. I was skeptical because the ingredients in this aren't exactly fast acting as far as I can tell. No caffeine. But it mentioned taking with caffeine to boost effect. Sure, I can do that. Well no matter if I took it on its own or with caffeine, I cant say I noticed anything significant. But since I had it, I figured I would just keep taking it as the entire supplement formula is pretty good, all stuff our bodies can use anyway, or are downright needful. I hadnt made any changes other than adding in the 3 products. Maybe I added in other probiotics (because as I learned more about probiotics, the more I realized we REALLY need the for overall health and wellness). I know the probiotics have added great value to my life, but I still wasnt (kinda still not) sure about INERGY. BUT, in reflection over the past month or so, I HAVE NOTICED, a reduced level of fatigue. For awhile, I was pretty much closing my eyes around 3p for a quicky nap. With the hours before that with a dragged down feel. Like I never fully woke up. Coffee minimally helps, matcha green tea helps a lot, but I still didnt feel overall "good". I'd drink my matcha to power through some basic daily tasks. Didnt really have anything left over for other tasks, projects, fun, etc. Could be that we're on the cusp of summer, and energy levels naturally rise. Could be that I have begun eating a lot better and greatly reduced my desserts intake (because I dont have that nagging desire for them--def thanks to probiotics!), or it could be a combo of everything, including the ingredients in this INERGY. That is why I cant say for sure if it is this, or a combo. But I do know I needed time with it, and did not experience anything significant in first couple of uses. I take this supplement and pretty much all of my probiotics (and prebiotics--do not skip those!) in the morning. I just wake and feel more motivated. I dont necessarily jump right into my day, but the start of my day is easier, less effort. Like I shaved a few years off. That sort of feeling. As I do chores and such, same feeling exists. I have been tackling projects that I have not been able to muster the mental or physical stamina for years. Sad. Things have been just different for me lately, and I absolutely contribute it to probiotics, prebiotics, and quite possibly this Inergy. As with the probiotics, it very well may take a month, two months, even three months to see/feel the cumulative effect. I think it helps in a more holistic manner. If you just need a big boost, and not concerned or interested in helping the body to get their in its own time, naturally, I would say B vitamins and matcha. That would produce a more immediate but short lived affect. Could really do both. I still drink my matcha for times I just need to have that added motivation/ambition feel. So no, this didnt seem to do a thing just by taking it a couple of times. And as I start my second bottle, I am not entirely convinced. But what is in it is good for me anyway, and I can say that the entire package (second time I got it I got it as part of the Previtalize, Provitalize, and Inergy I will probably continue with it, for awhile anyway. Or however long it seems to be helping me. I did consider stopping it, but at this time I do find value in seeing how much it can help. I dont rate on price. All their stuff is pricy. As far as probiotics go, good products are pricy. This Inergy? maybe the overall formula could be found for less, not sure. I'd give this 3.5 stars if I could. 4 makes it sound like sure thing, when I am still not entirely sure. However, I have decided to continue with it (so four stars), and I do think there has been some improvements just not immediate. I think it is worth the try if you are patient. Maybe you will be one of those that notice something right away!
