Toy box: the best folio cases for the iPad Air

The origami-inspired Cygnett Paradox Sleek (top; HK$309, hk.mobilefun.com) is one of the most flexible folding folios of all. Using an innovative, though rather large, folding stand design that can be tweaked to sit in multiple customised positions, the Sleek easily snaps onto an iPad Air. It has a rubberised cover with a soft microfibre lining and comes in yellow, black, pink and light grey. Also available is the Paradox Texture (which looks like cracked granite) and Paradox Lux (which includes a hand-stitched cover).

The pocket-stuffed Kensington Comercio Soft Folio (above right; HK$233, amazon.com) is a welcome space saver. Available in black, blue, olive, plum, red and grey, it is made from a soft, strong fabric that protects against accidental drops. The stand can support an iPad Air for films or - at a lower angle - for typing. Our favourite feature is its built-in business card slots, one of which has a transparent window to display your own card.

Not one for fashionistas - it only comes in white, silver or black - but it's hard to beat Belkin's QODE Ultimate Keyboard Case (above left; HK$1,029, hk.mobilefun.com) for productivity. Sporting an aluminium shell, it is attractive in many ways; with an iPad Air nestled inside, magnets hold it in different positions for typing and watching movies. Once it is set up, the excellent Bluetooth keyboard - good for 264 hours of typing between charges via mini USB - links automatically.
