Get up!

Do you have problems getting up in the morning? My sister who lives with me doesn't get up even after 4 alarm clocks have gone off and I've kicked her a couple of times! I've been thinking for a while about trying something else other than noise.
Now there is an alternative: a vibrating mattress avilable from a major bed maker from May 1. The produce targets bed-bound older people who have difficulty healing bed sores, and/or with waking up. The vibrations get stronger and stronger over a 4-minute period, until you think you're in the middle of an earthquake. The price is JPY75,000, and the maker expects first year sales of around JPY3m.
