  • Pillow tops – this is a mattress that’s designed to provide additional cushioning with a pillow topper.
  • Size

Typically, king size mattresses are available in 76″W x 80″L. However, this can vary depending on the brand. Be sure to check the exact size to ensure that it fits your room and bed frame before you confirm any purchase.

  • Depth

Checking the mattress’s thickness can help you determine how much support it can provide. Depending on your weight and required support, you can choose from 5-15″ thick mattresses. Normally, heavy users opt for thicker mattresses while lightweight users opt for mattresses with 7-9″ depth.

  • Weight

Though mattresses are generally heavy, there are lighter options if you need it to be easy to transport. You may opt for a memory foam or latex mattress if you want a lighter mattress.

  • Support

The mattress support can be determined by its ability to promote proper spinal alignment. It should not let your body sink too much which can cause body aches/pains. Since its support capacity decreases over time, select the one that can maintain consistent support for a longer period.

  • Firmness and Comfort

The right level of firmness and comfort may depend on your preferred sleeping position. For instance, most side and stomach sleepers prefer a softer mattress for extra cushioning. Back sleepers prefer a mattress with medium firmness for better back support.

  • Motion Reduction

A motion reduction feature allows you and your partner to move without disturbing each other since the mattress minimizes the motion transfer.
