In June 2020, GoodMorning.com commissioned Rus-Tec to provide independent 3rd party testing of multiple mattresses. Similar testing was done previously by Rus-Tec (5055-1,-2,-3,-4,-5,-6,-7) and Pure Mosaic (PMTM-4211-01 and PMTM-4320-01). Data from all test runs are represented in this document, as provided by GoodMorning.com from the previously validated reports. Rus-Tec followed testing procedures as directed by GoodMorning.com and attached in Appendix B. Below follows an overview of the testing procedures used as well as the results that they produced. Additional results can be found in Appendix A.
Figure 1: Reference Load 1. Plastic 5 gallon water cooler bottle. Size: 10.75” diameter, 19.5”
height, 42.3 lb weight
Figure 2: Reference Load 2. Spherical medicine ball. Size: 9” diameter, 10 lb
weight
As specified by the testing methodology, all testing was completed in a room with a temperature range between 18°C and 25°C and a humidity range between 25% to 50%, in order to simulate the environment of a typical residence. Mattresses were placed on a drop cloth on a flat concrete floor such that the top and sides were unobstructed.

Overview and Objective: Apply Reference Load 1 to the center of each subject mattress and measure the vertical displacement of each to establish their respective positions on a firmness (or “sinkage”) scale. A low relative vertical displacement shall indicate a firmer mattress, while a high relative vertical displacement shall indicate a softer mattress.

Figure 4 shows the critical measurements taken for Test 1 in order to determine the vertical displacement with Reference Load 1 applied.
The vertical deflection value of interest for Test 1 is 𝐷1 as defined below:
𝐷1 = 𝐷3 − 𝐷2 − 𝐷4
𝐷2 = 𝑀𝑒𝑎𝑠𝑢𝑟𝑒𝑑 (Deflection)
𝐷3 = 160 𝑚𝑚 (Constant)
𝐷4 = 𝑣𝑎𝑟𝑖𝑒𝑠 (Constant)
The vertical displacement, D1 can be found by inputting D2 into the above expression.
Overview and Objective: Apply Reference Load 1 to the edge each subject mattress and to measure the resultant vertical displacement of each to establish their respective positions on an “edge supportiveness” scale. A low relative vertical displacement shall indicate a mattress with more edge support, while a high relative vertical displacement shall indicate a mattress with less edge support.

Overview and Objective: Apply a reference impulse to the top side of each subject mattress, representative of human movement on the mattress, and measure the resultant peak acceleration of a calibrated accelerometer placed on the mattress a fixed distance away from the epicenter of the impulse to establish their respective positions on a “motion isolation” scale. A high resultant peak acceleration shall indicate less motion isolation, while a low resultant peak acceleration shall indicate more motion isolation.

Figure 8: Example Vector Magnitude Acceleration of one ball drop
The vector magnitude of acceleration as shown above in Figure 8 is calculated using the expression shown below.
a = √(𝑥2 + 𝑦2 + 𝑧2)
The responsiveness of the mattress can be seen at one sleep point as a result of an impulse being applied at the second. In order to record this data, a digital accelerometer (ADXL345) was used and set to record data at 400 Hz (400 data points per second).

Test #1: Mattress Firmness (or “sinkage”): Overview and Objective: Apply Reference Load 1 to the center of each subject mattress and measure the vertical displacement of each to establish their respective positions on a firmness (or “sinkage”) scale. A low relative vertical displacement shall indicate a firmer mattress, while a high relative vertical displacement shall indicate a softer mattress. Procedure:
1. Find the “approximate centre” of a given mattress sample:
a. Place 2 straight lines (tensioned string-lines or straight measuring tape), each from one corner of the mattress to the diametrically opposite corner (e.g. top right to bottom left and top left to bottom right).
b. Mark the intersection point of each straight line reference with masking tape - this is the
“approximate center” of the mattress.
2. Place Reference Load 1 on the mattress, such that a point halfway between the top and bottom extremes of the water bottle lies on the marked approximate center of the mattress; and that the spout of the water bottom faces the foot of the bed, such that the sides of the water bottle are parallel to the sides of the mattress.
3. Wait 30 seconds for the water cooler bottle to entirely stop moving to allow the system to settle to a static
state.
4. Place a 4-foot piece of ¼ inch thick aluminium across the surface of the mattress. The long side of the aluminium piece shall run parallel to the foot of the mattress. The metal shall rest beneath the spout of the bottle without touching the bottle.
5. Using a tape measure or metal ruler, measure and record the distance between the bottom of the spout and the
metal level immediately below it, without noticeably distorting the shape of the mattress at the measurement point.

Test #2 Edge Supportiveness: Overview and Objective: Apply Reference Load 1 to the edge each subject mattress and to measure the resultant vertical displacement of each to establish their respective positions on an “edge supportiveness” scale. A low relative vertical displacement shall indicate a mattress with more edge support, while a high relative vertical displacement shall indicate a mattress with less edge support. Procedure:
1. Find the “approximate middle” of the foot of a given mattress sample:
a. Measure the length of the top-facing edge of the foot of the subject mattress.
b. Divide the measurement by 2 and mark this point with masking tape - this is the “approximate middle” of the foot of the mattress.
c. Measure the height of the mattress at this point.
2. Place Reference Load 1 on the mattress such that a predetermined point of the water bottle lies on the marked
“approximate middle” of the mattress edge, and that the sides of the water bottle are parallel to the sides of the mattress. The long edge of the water bottle shall be parallel to the long side of the mattress.
a. This predetermined point of the water bottle is where the spout of the water bottle begins. That is, there
shall be 16 inches of the 19-inch water bottle lying ‘behind’ the edge of the mattress (i.e. on the mattress). The 3-inch spout shall extend off the edge of the mattress.
3. Wait 30 seconds for the water cooler bottle to entirely stop moving to allow the system to settle to a static
state.
4. Measure the distance between the bottom of the spout and the floor (variable X).
5. Add the height of the mattress (see step 1c) to 4.25 inches (variable Y).
6. Y minus X = vertical displacement.

Test #3 Motion Isolation: Overview and Objective: Apply a reference impulse to the top side of each subject mattress, representative of human movement on the mattress, and measure the resultant peak acceleration of a calibrated accelerometer placed on the mattress a fixed distance away from the epicenter of the impulse to establish their respective positions on a “motion isolation” scale. A high resultant peak acceleration shall indicate less motion isolation, while a low resultant peak acceleration shall indicate more motion isolation. Procedure:
1. Find two “Sleep Points” on a given mattress sample:
a. Measure the width of the mattress and divide by 3 (the “Edge Distance”).
b. Measure the length of the mattress and divide by 2 (the “Center Distance”).
c. Find the first point lying Center Distance from the foot of the bed and Edge Distance from one the side of the bed and mark this point with masking tape - this is the first Sleep Point.
d. Repeat the above step for the other side of the bed - this is the second Sleep Point.
2. Center a calibrated accelerometer on the mattress.
3. Drop a 10 lbs sphere (9” diameter) on the second Sleep Point on the mattress from a height of 39” above
the mattress surface.
4. Wait 5 seconds and record the peak acceleration experienced by the accelerometer.
5. Repeat 20 times and take an average.

Test #4 Bounciness: Overview and Objective: Drop a 10lb sphere (9” diameter) from a fixed distance on to the top side of each subject mattress and measure the resultant peak rebound height on its first bounce. A high resultant peak rebound height shall indicate more bounciness, while a low resultant peak height shall indicate less bounciness. Procedure:
1. Find the “Approximate Centre” of a given mattress sample:
a. Place 2 straight lines (tensioned string-lines or straight measuring tape), each from one corner of the mattress to the diametrically opposite corner (e.g. top right to bottom left and top left to bottom right).
b. Mark the intersection point of each straight line reference with masking tape - this is the
“approximate center” of the mattress.
2. Suspend a 10lb sphere (9” diameter) such that it is centered 39” directly above the Approximate Center.
3. Suspend a measurement scale, such as a measuring tape, vertically above the mattress such that it touches the mattress at a point 9” away from the Approximate Center towards the foot of the bed.
4. Wait 1 minute for the system to reach relative static equilibrium.
5. Release the sphere such that it lands on the Approximate center of the mattress.
6. Place the DSLR video camera, mounted on a static tripod located 6” from the mid-point of the foot of the bed
such that its line of sight is parallel to the top surface of the mattress, and that it is focussed on the vertically suspended measurement scale.
7. Wait 1 minute for the system to reach static equilibrium.
8. Begin recording on the video camera.
9. Release the sphere and wait 5 seconds.
10. Review the video and determine the maximum rebound point - that is, the point on the scale reached by the
bottom of the weight on its first rebound (if it rebounds).
11. Repeat 3 times and take an average.
