Best California King Mattresses Buying Guide

Before choosing the best California king mattress you should consider following options:

1. Types of California King Mattresses: While most mattresses are available in standard sizes, California king beds are typically only offered in two sizes:

Long California king: Typically 88 inches (224 cm) wide by 76 inches (193 cm) long, this size is often used in Europe and is suitable for couples who prefer to have separate beds.

Standard California king: Measuring 76 inches (193 cm) wide by 80 inches (203 cm) long, this size is commonly available in the US and is suitable for singles and couples who prefer to share a bed.

2. Thickness: Although all mattresses are measured by their length and width, thickness is often an important consideration for buyers.

Generally, California king mattresses are available in three thickness levels:

Single-inch (2 cm): This is the thinnest of all mattresses, and although it is suitable for back sleepers, it offers minimal support for other positions.

Twin-inch (4 cm): This is the most common thickness for California king mattresses. It offers enough support for back and side sleepers, but is not suitable for stomach sleepers.

Four-inch (8 cm): Suitable for all sleeping positions, this is the thickest of all mattresses. It is best suited to larger people and those who prefer a firm mattress.

3. Firmness: Just as they come in varying thickness levels, California king mattresses are also available in varying degrees of firmness. The best way to differentiate between them is by touch.

If a mattress feels hard and dense when you press down on it with your hand, it is likely to be a firmer option. If it feels soft and you are able to make an indent in it, it is likely to be a softer option.

4. Materials: The materials used to make a mattress can have a significant effect on its durability and comfort. There are three main types of materials:

Latex: This type of material offers great resilience and is often suitable for all sleeping positions.

Memory foam: This material is suitable for back and stomach sleepers, but is not suitable for side sleepers.

Hybrid: This is a combination of two or more materials, and is a good option for those who prefer a combination of soft and firm support.

5. Pocket coils: These are the individual coils placed inside the mattress to support the sleeper. The higher the coil count, the more stable and durable the mattress, but the more likely it is to produce a crumpling effect when you lie on it.

6. Grid system: The grid system is the framework that holds the pocket coils in place. The more coils in the system, the more stable the mattress, but the more likely it is to produce a crumpling effect when you lie on it.

7. Edge support: California king mattresses are often larger than standard mattresses, making them more likely to roll off the edge of the bed. A good California king mattress should have a good degree of edge support to prevent this from happening.

8. Firmness and support: A California king mattress should offer the same level of support as a standard mattress and should not cause excessive roll off.

9. Size: As a California king mattress is longer than a standard size, it is important to ensure that it fits in the bed frame or storage unit. This is especially important if you plan to move the mattress on your own.

10. Warranty: California king mattresses
