A Maxi Plus is a Maxi BuggyBoard with a Saddle. All Maxi Plus will therefore have the same fittings as a Maxi BuggyBoard, while ensuring there is enough space for the saddle.
You can find out if the buggyboard has been tested with your pushchair here, you can select your pushchair from the list to take you to a fitting guide with easy to follow images. This may need to be adjusted slightly when using with the saddle as our fitting guide is tested for the Maxi board only. The arm extenders come in useful to give the child more space to sit if the saddle is in use.
