Side sleepers between 130 and 230 lb — 9.5/10 on the Medium option, the strongest cell in this configuration. Consider the limitations: You sleep hot and are buying primarily for that. Despite cooling being the model’s entire pitch, temperature control measured only 7.5/10 — below several cheaper mattresses reviewed here.

Back and stomach sleepers over 130 lb — the clear strength, scoring 8.5 to 9.5 in independent fit testing and rising further above 230 lb. Consider the limitations: You are a side sleeper under 130 lb. At 6/10 this is the weakest fit result on the mattress — an 8/10 surface gives very little at the shoulder and hip.

Side sleepers at essentially any body weight — 9.5, 10, and 9.5 out of 10 across the three bands, the strongest fit profile recorded on this site. Consider the limitations: You share the bed with a restless partner: motion isolation measured 6.5/10, the weakest attribute here and the usual cost of a responsive coil unit.
