Consumer Reports has tested some high-tech mattresses.
In our labs, we put the It Bed through our tests for support, durability, and motion transfer with test subjects of different sizes and in various sleeping positions. The It Bed by Sleep Number offered only mediocre support for petite, average, and large/tall sleepers who sleep on their side or back and was worse than that for large/tall back sleepers. It’s also less forgiving when one partner changes positions, meaning the other will probably be shaken or jostled.
By contrast, in our tests its two brandmates, the Sleep Number i8 Bed, $3,000, and the Sleep Number c2 Bed, $800, provide very good support for all side sleepers, and even better for some who sleep on their back. And when one partner tosses and turns, the other is less likely to be bothered.
