This 8cm Plush Topper is my top pick for side sleepers because thickness and softness are the two most critical factors for this sleep position. You need enough material to absorb your protruding joints.
During my sinkage tests, this topper performed exceptionally well for side sleeping. I measured a sinkage of 5.8 cm at the hip zone. This deep cradling allowed my spine to drop into a perfectly straight, horizontal line, rather than being pushed upward by a firm surface. The pressure relief was immediate, eliminating the need to toss and turn to restore blood flow to my arms.
Despite the deep "hug" of the thick foam, the gel infusion worked well. I recorded a surface temperature of 29.2 degrees Celsius, which is very respectable for a plush memory foam product.
