Questions about beds and mattresses answered. And some stories told.

Nine Clouds Beds can!

If you are searching for a mattress in the unusual 3/4 size, sometimes referred to as a “three-quarter bed,” you are essentially looking for something that measures about 48 inches wide by 75 inches long. This unique dimension falls between a standard twin and a full-size mattress, making it less common than other options and therefore more difficult to find. Because it is considered a specialty size, the available selections are typically more limited.

However, certain companies, such as Nine Clouds Beds, can custom-build nearly any mattress size you need. If you want a very firm feel specifically in this size, here are some detailed recommendations to help make your buying process much more straightforward and effective:

Know Your Dimensions

The first step in choosing any mattress in a non-standard size is confirming the exact measurements of your bed frame. While 3/4 size mattresses typically conform to the 48-inch by 75-inch dimensions, there can be slight deviations depending on the manufacturer or the time period of the bed’s construction.

Many older or antique bed frames, for example, were designed with this three-quarter size in mind, and some sellers may list these mattresses under the term “antique bed size.” By accurately measuring the width and length of your frame in advance, you will know if you require an exact traditional 48-by-75 model or if you need a customized three-quarter mattress cut to fit unique proportions.

Focus on Firmness Types

When your priority is achieving a truly firm and supportive sleeping surface, the type of mattress material makes all the difference. Innerspring or coil mattresses traditionally provide more resilient support and often feel firmer than many types of foam, especially softer memory foam models.

For those who prefer foam while still wanting firmness, consider looking at high-density foam or natural latex mattresses. Latex in particular stands out as the best option in this category because it offers strong support and resists sagging or indentation over long-term use, which helps maintain its firmness. Another excellent option is choosing a dual-sided mattress design. Some distributors, such as Nine Clouds Beds, create reversible mattresses in which both sides feature a firm comfort level. 

This not only allows you to maintain firmness but also extends the mattress’s lifespan, since flipping the mattress helps distribute wear more evenly over time.
