My husband has tried various other brands of socks ,none of which
remotely resembled the L/XL I chose for him.
He finds Posey socks comfortable and true to advertised sizing.

Spex Adjustable Lateral Head Support
An upgrade to swing-away laterals is available to enable easier transfers if necessary.
For further support, install Spex thoracic lateral pads onto the head pad. Tip: The Spex curved pad works really well.
Two Mechanism options:
• Standard multi-adjustable mechanism
• Reach multi-adjustable mechanism (for more forward positioning)
Spex Head Support Advantage:
• Softly padded foam inner head support, with supple upholstery covers
• Powerful clamp mechanism allows super-quick release and prevents lateral movement
• Extra strong and non-wobbly. Ball linkages secure with hex-head bolts which can be tightened fast.
• No protruding bar at rear.
• Exceptional carer-friendly design doesn’t harm anyone pushing the wheelchair.
• Goose-necked stem permits additional fine-tuning, forward and rearward.
