Lazy Couch full review
There are complicated products, and there are simple ones. And as far as simple goes, it's hard to beat the Just Mobile Lazy Couch. Basically it's a pair of feet that raise your MacBook, or iPad (or whatever you put them beneath) by about an inch.
Why would you want to do such a thing? In the case of a MacBook it elevates the keyboard, making it easier to type on (it makes it more like a traditional ergonomic keyboard). Just Mobile also claim it facilitates a cooler and quieter operation, although we're not quite as convinced on this front.
In the case of the iPad it raises the screen by a small amount making it slightly easier (but not by much) to type on. The effect is similar to the Apple case when turned around and used as a stand.
The two stands interlock together to form a neat portable package, and they are made of rubber and aluminium to match a MacBook. At £14.99 it's easy to be cynical about the price, but it's well-made (as well-made as two chunks of aluminium with a bit of rubber attached can be) and if you like your MacBook or iPad raised then it's certainly neater than just propping it up against a book.
