Mattresses test program at
Consumer Reports. In our lab tests, Mattress
models like the Mariela are rated on multiple criteria, such as those
listed below.
Petite side sleeper:
A high score means the mattress supports smaller side sleepers well. For petite sleepers, we use a 5'0", 121 lb test dummy to assess how well the spine stays aligned in a side sleeping position.
Average side sleeper:
A high score means the mattress supports average side sleepers well. For this score, we average the petite and large/tall side sleeper scores to assess how well the spine stays aligned in a side sleeping position.
Large/Tall side sleeper:
A high score means the mattress supports large/tall side sleepers well. For large/tall sleepers, we use a 6'2", 220 lb test dummy to assess how well the spine stays aligned in a side sleeping position.
