What to Consider Before Buying a Mattress

Before purchasing your next mattress, here are a few factors to keep in mind:

Room size

Take into account the dimensions of the mattress and ensure your space can accommodate it comfortably. California king mattresses require extra length, while king mattresses are wider.


King mattresses are expensive, with higher-quality options typically costing over $1,000. California king mattresses are even pricier, ranging from $1,200 to $1,600. Remember to factor in the cost of bedding and a bed frame as well.

Sleeping preferences

Choose a mattress firmness that suits your sleeping position. Side sleepers generally benefit from medium to soft firmness, while back and stomach sleepers require a firmer surface for proper spinal support.

Type of mattress

Innerspring mattresses provide support and comfort, while foam beds offer a contouring feel. Hybrid mattresses combine the best of both worlds.

Body type

Consider your weight when selecting a mattress. Heavier individuals (over 230 pounds) may require a more supportive option like a hybrid mattress, while lighter individuals can benefit from foam beds.

Use of bed

Consider the frequency of bed usage. If the mattress will be used regularly, investing in a higher-quality and more durable option makes sense. If it will be used sparingly, you can opt for a more budget-friendly choice.
