Alarms for heavy sleepers

Loud is only half the answer. Our adjustable-volume clocks go up to a level that is genuinely hard to sleep through, and the alarm ramps so the first seconds do not shock the whole house.

For the people sound simply does not reach, the vibrating clock goes under the pillow. It is rechargeable, it shakes at five strengths, and it wakes one person without waking two. Hard-of-hearing buyers say the same thing in their reviews.

If a partner shares the bed, pick by wake style: buzzer for one, shaker for the other, and nobody negotiates over the volume knob again.
