Space in Hong Kong homes are usually so scarce so there is little space to store away any unused furnishings, that many people are keen to just offer items to giveaway for free. But you must arrange pick up of the items yourself. Hiring a dispatch van service is quite reasonable, although you would need to arrange the actual moving and lifting yourself as the driver usually doesn't help out in this area.
A van trip from Central to Wanchai should cost around HK$60 to 70. Its best to ask for a price quote when you ring up for the van.
Some van service contacts (most services only speak Cantonese so have someone help you if you can't )
