I just received the Britax Boulvard as a replacement for my Decathalon which was recalled. Britax has the best customer service. I called them to explain that it was nearly impossible to tighten the straps on my Decathalon (which I had for almost 3 years) and Britax offered to ship me a new seat of my choice, free of charge. I chose this seat in the Barrington Pattern and I am so glad that I did.
When the seat arrived, I noticed that it seemed a lot more sturdy than the Decathalon. The fabric was plush and looked so comfortable. I put my son in it to adjust the straps and he just loved it.
The seat was so easy to install and I love the way the latch is positioned on this seat. You can get the seat so tight in your car that it is as if the seat were a part of the car.
My son loved riding in the seat. He used to cry in the Decathalon, which seemed lower that this seat. Now, he is higher up and looks much more comfortable. I love this seat and I love Britax.
We also have the Regent for our 2 year old and we love that seat as well. I highly recommend Britax all around. If you are debating between this seat and the Decathalon or Marathon, I would say go with this seat - the Decathalon is not of the same quality as this seat and the Marathon does not have the same features. There is only a slight price difference so I would go with this one. Also, the pattern on this seat is much nicer in person!
