Comparative effects of sleep on a standard mattress to an experimental foam surface on sleep architecture and CAP rates.

The comparative effects of sleep patterns and rates of cyclic alternating patterns (CAP rate) in a high quality innerspring mattress were compared to those on a unique foam support mattress in 10 normal subjects. Results showed no differences in sleep stages, number of wakes, or total sleep time between the two conditions. CAP rates were significantly reduced on the foam surface. CAP rate was sensitive to the first-night effect on both surfaces, but was blunted on the foam mattress.
