p in a circle is dry clean in percloetheline , the A symbol is quite rare but its means in can be dry cleaned in all solvents ,im talking dry cleaning shops, use a mild pre spray and cool extraction on a section on the back see how it responds or wet a small area and press with your finger for 30 secs if it does not flatten you will know to carry on with a water system.
it does look like a dralon,velour,cheap velvet. i would buff up the base and take the covers to a dry cleaners
