Ready to go with room to grow! The Poplar™ S convertible car seat takes the stress out of moving to the next car seat stage thanks to the patented ClickTight® installation and slim SpaceSaver™ design. This convertible car seat accommodates up to 50 lbs when installed rear-facing and easily switches to a forward-facing car seat as your child grows. ClickTight technology provides fully open seat belt paths that are clearly labeled and easy to access, and the automatic tensioner takes care of the tightening.

This car seat lets you easily adjust the 14-position no-rethread harness and headrest to help create the perfect fit. The removable infant insert helps to properly position infants 22 lbs and under. There are 2 additional premium inserts that help create refined comfort and a tailored fit. The ReboundReduce™ stability bar easily attaches to the car seat when installed rear-facing, helping to minimize movement in the event of a crash. Slim outside and spacious inside, this convertible car seat features 17-inch SpaceSaver™ technology designed to fit 3-across* without compromising on trusted Britax safety and premium comfort.

The rear-facing car seat includes a patented SafeCell® crumple zone and a V-shaped top tether to help manage crash energy. Carbon steel frame and belt paths provide strength and stability. The car seat cover fabrics are naturally flame-retardant with no added FR chemicals, and they’re safe to machine wash and dry time and again. *Britax cannot guarantee 3-across installation fitment in all vehicles

Works only moderately well to keep coffee hot
Color: Light Blue
Not quite what I expected. Although the base heats up as described, it does not keep my coffee as warm as I would expect at the highest temperature.

Excellent Warmer and the Rubber Pad is a very nice extra...
Color: 301 Black
... This really fits my cups perfectly... Just like it was made for these very cups. I wish I had found this one a long time ago and I am considering purchasing another one! Not Sure why they call it a "Coffee Cup Warmer", it would better known as a Beverage Warmer... but either way, it is a great unit and works great. Heat is great, I don't drink coffee, but it works equally well on Tea... This is an Excellent Value for the money.... Not throwing away cold tea and it stays HOT and mostly fresh! I wish I had found this a long time ago, much better than my older units. I will be purchasing another one in the near future! I think this unit is built well and will last a long time and I will... "Coffee Flavor" - No Thanks.... But it works great on HOT TEA! - Excellent Warmer and the Rubber Pad is a very nice extra... (It will help in not getting burned when I accidentally touch the heating surface by mistake! Excellent thought from the designer! You can adjust how hot to keep it and has a digital display to show the Temp that it is keeping the temperature of. I really like this item and I do highly recommend for Hot Tea and Coffee Drinkers, Works great for Hot Chocholate as well!... Doesn't let your drink get cold!

It's exactly what I was looking for!!
Color: 301 Pink, Color: 301 Pink
This one beats all the other mug warmers I researched on Amazon! That circular pad around the mug can come up and it's flat to the edges so I can sit my whole little flat bottom glass pot of tea directly on it and it keeps it hot, and I mean HOT all day! It also has 6 settings. The 130 barely keeps things warm for me but it goes up to 180 degrees! At 180 You can put your completely cold cup of tea that you left out all night and forgot about, turn this thing on and it will reheat your stale tea (that you probably shouldn't be drinking now) back up to pipping hot, steam coming off, you need to blow on it to take a sip levels! (Yes, I know you shouldn't drink tea that you left out all night but I'm just being real). If you want your hot drink to stay actually HOOOT but also have the option for it to be just lukewarm if that's you're thing, then this thing is for you! It also has a timer for shut off which is neat. The $20 spent on this has changed my life haha!
