What to look for in a California King PressureSmart mattress

When shopping for a California King PressureSmart mattress, consider your sleep style, comfort preferences and the features that support restful zzz's.

1. Pressure Relief

Look for comfort materials designed to cushion areas such as your shoulders, hips and lower back. Pressure-relieving foam can help distribute your weight more evenly for a more comfortable night’s sleep.

2. Mattress Feel

Choose a feel that matches how you sleep and what feels most comfortable to you. PressureSmart mattresses may be available in plush, medium or firm options, so consider whether you prefer a softer, more cushioned surface or a firmer feel.

3. Support And Alignment

A supportive mattress should help keep your spine comfortably aligned throughout the night. Zoned support and individually wrapped coils can provide targeted support while limiting motion transfer between sleep partners.

4. California King Size

A California King mattress offers extra length, making it a helpful option for taller sleepers or anyone who enjoys more room to stretch out. Before purchasing, measure your bedroom and confirm that your bed frame, foundation and bedding fit the California King dimensions.
