Best mattresses that don't sag

By Katie Dyal

When it comes to choosing a mattress that holds up over the years and supports your body for a restorative night’s sleep, you want a mattress that is not prone to sagging or drooping. Ill constructed mattresses that cut corners on support, materials or construction will sag or droop under the weight of serious use.

Since sagging happens over time and you don’t notice it right away, a sagging mattress can cause discomfort and affect sleep gradually. Guard against the kind of sleep disturbance and orthopedic issues that can arise, by choosing a mattress that doesn’t sag. Typically, latex and air mattresses are the least likely to sag. Here are the best mattresses that don’t sag.

How to find the best mattresses that don’t sag

The only mattress that will never sag is a properly inflated air mattress, but latex is the most solid, durable choice after the air mattresses. Consider material, function, usage, and longevity when purchasing.

Material: Latex is the most durable, sag-resistant material that isn’t an inflatable for a mattress. 

Function: If a mattress will be used by smaller people or children, it will hold up longer without sagging regardless of the material you choose. 

Usage: Any mattress that gets daily use has the propensity to sag sooner. The more usage your mattress will get, the more critical it is to choose air or latex. 

Longevity: If you’re planning to replace your mattress every three to five years, coils and memory foam mattresses of high quality will be durable enough to purchase.


Now that you have a better understanding of what mattresses resist sagging the best, you’ll be able to buy a mattress with confidence. We hope you’ve found your perfect mattress in this list of best mattresses that won’t sag.
