2015 Britax Marathon ClickTight Review

2015 Britax Marathon CT Convertible Carseat Review

Click here to enter our Marathon CT GIVEAWAY!!!

MA CT twilightClickTight isn’t a new-new technology anymore, since it was introduced on the Frontier and Pinnacle combination seats almost 2 years ago, but what *is* new is how it’s being applied to Britax’s convertible carseats. Britax has taken ClickTight and made it so that it takes seconds to install a ClickTight convertible seat. The new Britax Marathon CT is a Euro-styled, well-padded carseat designed to fit newborns to preschoolers.

Here’s a quick overview of the differences between the three new ClickTight convertibles.  All Britax CT convertibles have the ClickTight Installation System, an impact-absorbing base with 7 recline positions, rip-stitch energy-absorbing tether, HUGS harness pads, a steel reinforced frame, EPP foam, and other side-impact protection features.


  • Britax Marathon ClickTight – This model has a no-rethread harness and standard rubber HUGS pads. The top harness slot height and the overall height are about 2 inches shorter than the Boulevard CT and Advocate CT models.  MSRP $329.99

MA vs BV

  • Britax Boulevard ClickTight – All the features of the Marathon CT plus SafeCell HUGS pads; deeper, plastic-surrounded headwings; “Click & Safe” snug harness indicator, top harness slots and overall height 2″ taller than Marathon CT. MSRP $369.99

Britax also markets a less expensive series of smaller convertibles.  We recently reviewed the 2015 Britax Boulevard G4.1 that often sells for less than $270 at Amazon.  Its sibling, the Roundabout G4.1 can be found online for under $170, and sometimes less when on sale.

Weight and Height Limits:

  • Rear-facing 5-40 lbs. AND child’s head is 1” below top of head rest
  • Forward-facing 20-65 lbs., 49″ or less, at least 1 year old*

*Britax recommends that children ride rear-facing to the highest weight or height specified

Marathon CT Overview:

  • ClickTight installation system (also acts as a built-in lockoff device)
  • Complete Side Impact Protection – deep protective shell

  • 2 crotch strap/buckle positions
  • 2 position buckle with EZ-Buckle System to keep buckle to the front and forward of the child when loading

  • Energy-absorbing, rip-stitch Versa-Tether®
  • 7 recline positions to help achieve a proper recline angle in any vehicle
  • Smooth bottom base with grippy edges that won’t damage vehicle upholstery

Quick Look: 2015 Britax Boulevard Review “G4.1″

Britax Advocate G4.1, Britax Marathon G4.1 and Boulevard G4.1 Review Update for 2015

The Britax Boulevard G4 and other Britax G4 convertibles are getting a facelift for 2015. So, this review is a very minor update to our 2014 Britax Advocate Full Review. We recommend reading our full review for all the details of the Britax G4 and G4.1 convertibles, as this review will just cover the updates for 2015. The Britax G4 convertibles have not changed in any significant way, but only have some minor labeling and marketing changes moving into 2015 with the unofficial G4.1 designation. Here are the changes:

  • Label added to infant positioning pillow.  MUST be used for children weighing 22 lbs. or less in a rear-facing position.  DO NOT use over 22 lbs.  DO NOT use in a forward-facing position.
  • Boulevard now marketed with Complete Side Impact Protection PLUS, indicates the energy-absorbing head restraint system with side impact wings.
  • P1040660Maximum limits continue to be 65 pounds forward-facing (seatbelt), 50 pounds forward-facing (LATCH) and 40 pounds rear-facing.
  • Top tether length shortened; extenders available
  • Rear-Facing accessory tether strap will be revised to fabric-only loop
  • Red accents added to height adjustment lever and recline lever.
  • New Britax Logo with SafeCell Impact Protection.
  • New 2-color box; helps identify the 4.1 model (photo, right)
  • Anti-Rebound Bar is an optional accessory

Boulevard G4.1 Pros:

  • One of the easiest LATCH installs on the market
  • Easy front adjustment for harness height with 10 positions
  • EZ Buckle System is wonderful; no digging out buckle from under the child!
  • Two crotch strap positions, three recline positions
  • Better than average fit rear-facing in smaller cars
  • Ability to tether rear-facing or use anti-rebound bar (optional accessory)
  • Click & Safe harness adjuster helps you know when the harness is adjusted reasonably well
  • Seated maximum shoulder height label for visual reminder of when seat is outgrown
  • Infant positioning pillow provides excellent fit on newborns
  • Made in USA!



There are no major changes for 2015 on the Britax Boulevard G4.1 or the similar Roundabout, Marathon and Advocate G4.1 models.  The big change for Britax was the introduction of the Britax ClickTight Convertibles, with more features, higher limits and a bigger price tag.  Meanwhile, the G4.1 models continue to be great convertible carseats at a lower price point.  The lowest priced model, the Britax Roundabout G4, sells for under $145 at some retailers.  Meanwhile, the Advocate G4.1 packs the most premium features, is easier to use than many competitors and comes with unique, patented external side impact cushions.  All install easily with LATCH and fit well in small cars.  For those reasons, we continue to include them on our Recommended Carseats list!

The 2015 Britax Boulevard G4.1 sample used in this update was provided by Britax USA, no other compensation was provided and all opinions are my own.

Evenflo Symphony DLX Elite All-in-One Carseat Review – A Concerto of Safety, Function & Style

Evenflo ProComfort Symphony - stockHere at CarseatBlog we’re very familiar with the Evenflo Symphony which first debuted back in 2008. We’ve reviewed every generation of this popular All-in-One carseat and I’m happy to report that the latest DLX/Elite version continues to impress!

First, let’s clarify that there are two different models of the Symphony that are currently available on store shelves. The Symphony DLX (aka Symphony Elite) is the premium model with SureLATCH connectors. The Symphony LX model has differently shaped headwings and standard push-on lower LATCH connectors instead of the patented, self-ratcheting “SureLATCH” connectors.

Both models are very nice but if you’re drawn to the less expensive LX model because you prefer the regular push-on LATCH connectors, or you’re just trying to stay within a more limited budget, the Symphony LX model still has a lot of great safety and convenience features to offer. Just make sure you’re looking at the newest LX model. The new LX models have the dual integrated cup holders – the older LX models do not and the older models also lack the deeper headwings for enhanced side-impact protection.

In this review we will focus on the premium DLX (aka Elite) Symphony model. There are different versions of the DLX model and some versions are exclusive to certain retailers like Target and Babies R Us. Here is a breakdown of the different DLX models, which stores carry them, and what’s special about that particular version:

ProComfort Symphony DLX – Target exclusive. Cover has Buckle Pockets and “Gel-Matrix Technology”  inside to reduce pressure points and improve comfort. ProComfort fashions include “Cambridge” (Black/Green) & “Alexandria (Black/Pink).

Evenflo Symphony - ProComfort Evenflo Symphony - ProComfort - pinkEvenflo ProComfort Gel Matrix Pressure Relief graphic

Platinum Symphony DLX – Babies R Us exclusive. Cover has Buckle Pockets and OUTLAST® Performance Fabrics which absorb hot and cold temperature, releasing as needed. Outlast® technology, originally developed for NASA, utilizes phase change materials that absorb, store and release heat for optimal thermal comfort.

This technology has the ability to:

  • Actively absorb and store excess heat, helping to reduce overheating
  • Allow the child to stay at a balanced temperature and prevent chilling during the cooler months; if the child’s skin temperature drops, the stored heat is released
  • Reduce perspiration so the child stays drier and more comfortable

The thermal image below shows the difference in body temperature after 30 minutes of sitting in the same style carseat – one with OUTLAST®  fabric and one with regular fabric. If you live in a warm climate or just have a kid who is a sweatbox – this technology will help keep your kiddo feeling comfortable all year round.

Symphony Elite – Available at Amazon. Modesto (Blue) and Paramount (Black) fashions are the newest Symphony Elite fashions available on Amazon.com. These new fashions include the buckle pockets feature. Ocala (Red) & Porter (Green) do NOT have the buckle pockets feature.
