If you’re a stomach sleeper, consider a firmer hybrid option, such as the Helix Dawn Luxe, for better support. The Midnight Luxe has a higher price tag than other hybrid models, which may be a drawback if you’re looking for a more budget-friendly California King mattress.

More on the Best California King Mattress
Things To Consider When Looking for the Best California King Mattress
Weight
The weight of both the mattress and the user is key when choosing the best California king mattress. Heavier sleepers often benefit from a firmer mattress, like a hybrid or pillow-top, to prevent excessive sinking and keep the spine aligned.
On the other hand, lighter sleepers may prefer a softer memory foam option for better contouring. A heavier mattress may also be challenging to move, so finding the right balance ensures ideal support, pressure relief, and convenience.
Sleeping Position
Side Sleeper
Side sleepers often experience pressure buildup around their shoulders and hips, which can lead to discomfort or sore spots when waking up. The best California king mattress for side sleepers should offer contouring support to relieve these pressure points and promote healthy spinal alignment.
If you’re a side sleeper, choose a California king mattress with softer comfort layers, such as memory foam or a plush hybrid top, to cushion the body. Look for zoned support or individually wrapped coils to provide firmer support at the hips and softer cushioning at the shoulders, ensuring proper spinal alignment.
Back Sleeper
If you sleep on your back, finding the best California king mattress that keeps your spine aligned is key to avoiding lower back pain. Back sleepers often run into issues with mattresses that are too soft, which can cause the lower back to sink and strain the spine.
The best California king size mattress for back sleepers is usually a medium-firm to firm mattress that offers enough support without being too stiff. A hybrid or firmer memory foam mattress works well, as it provides gentle cushioning while keeping your back properly supported for a comfortable night’s sleep.
Stomach Sleeper
Stomach sleepers often struggle with mattresses that allow the midsection to sink too deeply, causing strain on the back and neck. The best California king mattress for stomach sleepers will keep the body supported and aligned.
The best rated California king mattress for stomach sleepers should have a firm surface with just a bit of cushioning to stay comfortable while preventing pressure on the lower back. A California king hybrid mattress usually works best because it provides steady support to keep the hips level and spine aligned.
Combination Sleeper
Combination sleepers shift positions throughout the night, making it tricky to find a mattress that suits every sleep style. When picking the best California king mattress for changing positions, focus on features like pressure relief, support, and responsiveness.
Hybrid, latex, or innerspring mattresses usually provide a good mix of comfort and easy movement. Firmness is also key. A medium-firm king size mattress often works well for combination sleepers, providing balanced support and comfort.
On-Edge Sleeper
On-edge sleepers tend to sleep near the edge of the mattress, which can lead to issues like feeling unstable or unsupported on softer beds. The best California king mattress for on-edge sleepers should have strong edge support to prevent sagging and provide a stable surface.
Look for features like reinforced edges, common in hybrid or innerspring mattresses, as these often offer the best combination of durability and support. A medium-firm feel can also provide stability while accommodating different sleep styles.

Material
The materials in a California king size mattress play a crucial role in comfort, durability, and health. High-density foams and durable latex provide excellent support and resist sagging. Cooling features like gel-infused foam or open-cell latex help regulate body temperature.

Investing in premium materials ensures the best California king mattress delivers superior comfort, long-lasting support, and a cleaner, more eco-conscious sleeping environment.

Breathability
Breathability in a California king size mattress is crucial for uninterrupted, comfortable sleep. Mattresses lacking breathable features can trap heat, leading to discomfort.

Temperature Regulation
Cooling Cover
If you’re a hot sleeper, prioritize a mattress with a cooling cover to ensure a restful night. Cooling covers, like Helix’s GlacioTex, pull heat away from your body, making them a great feature in the best California king mattress for those who run warm.

Quilted-Cotton Topper
A quilted cotton topper is a cushioned layer sewn into the mattress cover, typically filled with cotton, to enhance comfort and breathability. It adds a natural layer of airflow, allowing heat to escape from the mattress surface.
Cotton’s excellent ventilation reduces moisture buildup, helping you stay cool and dry. If you’re searching for the best California king mattress that combines comfort with breathability, a model featuring a quilted cotton topper is a fantastic option to keep you refreshed throughout the night.
