Can you scientifically define
the words 'most comfortable'?
We conducted the first double-blind mattress comfort test
to compare Morphiis to all of the highly advertised national brands
We beat all of the national brands
in a double-blind comfort test
Pressure maps don't lie!
- No pressures
- Pressure points
All of these pressure maps are the same person lying on different mattresses.
DISCLAIMER: The above pressure maps represent 7 of the 175 readings taken during the test. They should only be evaluated in the context of the entire double-blind test as reported by Dr. Black. These pressure maps represent an example of a favorable portion of the test with one of the test participants. Other maps with different participants might have different results. Testing protocols were developed by Dr. Jed Black of Stanford University's center of Sleep Science and Medicine.
The double blind mattress comfort test
How do you define 'comfort'? All mattress companies claim that their mattress is the most comfortable, so how can anyone objectively decide?
Dr. Jed Black was engaged to develop a proper testing protocol and offer a research assistant to oversee the actual testing.
MATTRESSES TESTEDAll mattresses tested were TWIN size.Perfect Pressure, 10 inch ($850-Queen Price)Tempur-Pedic Cloud Supreme, 11.5 inch ($2499 - Queen Price)Sealy Posturpedic Knighton, 13.5 inch ($1400 Queen Price)Simmons Recharge 1000, 12 inch ($1400 Queen Price)Serta iCloud Savant Everfeel, 11.5 inch ($1575 Queen Price)Select Comfort P5, 11 inch ($2299 Queen Price)Casper, 10 inch ($85O Queen Price)
TESTING LOCATION, DATE AND ENVIRONMENTThe tests were conducted on 4 days during a 7-day period at the Sheraton Palo Alto from Oct. 15 to Oct. 22, 2015.Space environment temperature was maintained between 68 and 72 degrees during testing and the humidity was recorded.
TESTING PROTOCOLDr. Black did not choose either the test equipment used or the specific mattresses that were tested nor does he express an opinion on the results. Stanford University was not involved in the test nor do they endorse the mattress.All mattresses were covered with a fitted-sheet such that the test coordinator did not know which results were for which mattress brand and the 4 participants never knew which mattresses they were lying upon.Two woman, weighing 120 lbs. and 170 lbs., and two men, weighing 169 lbs. and 210 lbs., were the human test participants.A non-human ‘test jig’ was also used as a ‘participant’ to eliminate the inherent irregularities of human testing.Each of the 5 participants lay on each mattress 5 separate times on their side. They were asked to try and lie the same way each time.Each participant lay on the mattress for 3 minutes before a pressure reading was taken for their shoulders and hips.175 individual readings were taken (5 participants x 5 trials x 7 mattresses).
TEST COORDINATORAngelica Pritchard, a researcher chosen by Dr. Black, and paid directly by Pressure Perfect for her time, to record all readings according to the protocol developed by Dr. Black.
TEST RESULTSThe results presented herein were averaged as follows:
The results used a 5-inch x 5-inch pressure map recording area for both the shoulder and hip readings.The high and low results of the 5 different readings per participant were eliminated.The remaining 3 results were averaged to obtain an average pressure score for each participant for each mattress tested.The shoulder and hip average pressure scores were then averaged to obtain the mattresses’ overall pressure score.Based on the above, using just the four human participants, the following were the averages:Based on the above, using just the non-human test jig, which eliminates the inherent issues with a human participant trying to lie the same way on 5 separate occasions, the following were the averages:
