The Fusion is available in two configurations:
Standard - powered tilt, manual recline, normal legrests
Advanced - powered tilt, powered recline, elevating legrests
Powered tilt is an oft sought-after feature as provides a more comfortable position to sit, and helps with pressure relief and hoisting. However, it is normally only available on high-end prescriptive powerchairs. The same applies to powered recline, which when combined with elevating legrests allows you to lie back in your wheelchair and relax.
Ion seating comes on the Fusion - this allows a level of adjustment to the seat size, and both armrest and legrest positions. While not featuring the same level of adjustability as fully-prescriptive seating that would provide a "perfect fit" it provides a more precise fit than basic "one size fits all" seating.
Designed for use both inside and out, the Fusion's rear-wheel drive excels outdoors, giving it the torque and power necessary to get the wheelchair user around, while rear suspension keeps them comfortable. However, the larger footprint of the chair and rear-wheel drive does make it less manoeuvrable indoors then compact mid-wheel drive models such as the Jazzy Select 6.
If you need tilt or recline but don't have the budget for a prescriptive powerchair then the Fusion is a good choice, and there isn't another chair close in price with these options.
If you have restrictive indoor spaces to manoeuvre around we would recommend a home consultation first, as the Fusion can struggle with these.
