A lot of iPad cases already come with an integrated stand, so getting a separate one isn't the cards for a lot of users. If you want limitless flexibility in your viewing angles, though, you need the LapWorks iPad Recliner.
More than a simple stand, the accessory is designed to allow use of your slate without having to set it down on its back. Set it up on a tabletop and use it to position the iPad at a whole host of angles, whether for viewing movies, typing or browsing.
The iPad Recliner behaves more like a chair than a stand. Just lay the slate on the platform (both portrait and landscape modes are supported) and adjust the incline (there's a knob in the back) in 32 possible positions from 4.25 inches above the surface (perfect for typing) to 8.25 inches (for viewing movies).
Designed for stability, it's made from heavy-duty hard ABS plastic, with a wide base for a steady hold. Billed as the "Lazy Boy of iPad loungers," it comes with a no-slip rubber cushion on the platform to keep the tablet comfy, as well as a soft rubber strip along the top as "headrest." It can accommodate other tablets and e-readers, so you can use it with a whole host of consumer gadgets, too.
Granted, the LapWorks iPad Recliner is a bit bulky. It's designed for home and office use, though, not portability, so it does it's job handily. Available in one two-tone color (silver and black), you can get it for as low as $29.95.
