What type of bed is best for heavy people?

All foam mattresses, such as latex and memory foam, and innerspring mattresses with a thick coil gauge are a great choice for heavier people. Foam mattresses provide exceptional pressure relief and use foam cores to ensure proper spinal alignment and back support. They also tend to last longer than innerspring mattresses in the same price range. If you want to keep your costs down, look for an innerspring mattress that has a tied coil system with thick coil gauges (below 15). In a tied coil system, the coils are linked together, resulting in a very solid, strong level of support. If you sleep with a partner and motion transfer is an issue, then you should consider an individually pocketed coil system with a thick coil gauge.

The best way to find out if it's time for a new mattress is to ask your body. Do you wake up with aches and pains? Do you toss and turn a lot throughout the night? Can you see excessive body indentations and deep cavities in the mattress? These are the best ways to determine whether or not your mattress is still capable of properly supporting your body. If your mattress isn't delivering the amount of comfort and support your body requires for healthy sleep, then you should purchase a new one.

Why is my new mattress an inch shorter or longer than the standard size?

Mattress companies work with an "Engineering Tolerance" rule when it comes to manufacturing a mattress to the distinct size of the industry standard.
