If your mattress feels a little too firm or thin, you might wonder if layering two beds on top of each other can provide a quick fix. While double-stacking mattresses may seem like an easy upgrade, there are some important factors to consider first.
In this detailed guide, we’ll explore the pros, cons, and expert recommendations regarding double-stacking mattresses so you can make an informed decision.
What Is Mattress Double-Stacking?
Mattress double-stacking simply refers to using two mattresses stacked directly on top of each other on the same bed frame or base. Some of the reasons people double up on mattresses include:
- Adding more overall thickness and height
- Softening a too-firm bottom mattress
- Extending the lifespan of old mattresses
- Separating partners who prefer different firmness levels
- Improvising while waiting for a replacement mattress
While this may seem like a convenient solution, there are some downsides associated with placing one mattress directly over another. We’ll go over the key considerations next.
Potential Pros of Double-Stacking Mattresses
Here are a few reasons why double-stacking two mattresses may appeal to certain sleepers:
Increased Height - For taller individuals or those who prefer to sleep “on top” of their bed rather than sink into it, doubling up mattresses can provide more loft. This may make it easier to get in and out of bed.
Softer Feel - Placing a softer mattress on top of a firmer one can provide more cushy softness while retaining underlying support. This balances comfort and support for side sleepers.
Extended Mattress Lifespan - Rotating two mattresses seasonally may allow each one to wear more evenly, extending their usable lifespan.
Accommodating Different Preferences - Partners who can’t agree on mattress firmness can double up to customize each side.
Quick Fix While Waiting on Delivery - Short-term double stacking can act as a placeholder bed while waiting for a brand-new mattress delivery.
For those seeking more plush softness or height, double-stacking may seem like a cost-effective and convenient way to adjust a sleep surface. But there are also some potential downsides to consider before layering two beds.
The Cons of Stacking Two Mattresses
Here are some of the key disadvantages and issues posed by double-stacking mattresses that you should keep in mind:
Void Warranties - Most mattress warranties are voided if two mattresses are stacked, as it goes against manufacturer guidelines for support and longevity.
Causes Premature Wear - Double-stacking essentially doubles the weight and pressure on each mattress, accelerating sagging, impressions, and deterioration of foam layers.
Disrupts Airflow & Hygiene - Lack of airflow between tightly stacked mattresses can lead to moisture buildup, mold growth, and dubious hygiene.
Makes Rotating & Cleaning Difficult - Trying to rotate and clean two bulky stacked mattresses is challenging. Mattresses really require space around them to properly air and clean.
Reduces Support - The bottom mattress becomes highly compressed, negating its ability to adequately support sleepers. This misalignment can cause or worsen pain.
Excessive Height - Extremely tall double-stacked beds may be difficult to get into and out of easily, especially for seniors or those with mobility issues.
Excessive Softness - Too much piled-up softness from two beds lacks the underlying firm support required for proper spinal alignment. This can contribute to sinking, back pain, and restlessness.
Overall, regularly double-stacking mattresses usually does more harm than good in the long run, according to sleep experts. Next, we’ll examine what specialists recommend.
What Do Sleep Experts Recommend About Stacking Mattresses?
Sleep medicine experts and mattress manufacturers overwhelmingly agree that double-stacking two mattresses permanently is inadvisable. Here's their guidance:
- Occasionally rotating two mattresses is okay, but they should not remain constantly stacked. Mattresses require space for airflow to prevent mold risks.
- Using mattress toppers for added softness is safer than a whole extra mattress, which throws off support and alignment.
- If partners have very different comfort preferences, split mattresses that allow custom firmness on each side are an alternative solution.
- To avoid voiding warranties, always follow manufacturer instructions for mattress use and avoid stacking.
- If your mattress feels unsuitable, the best fix is to invest in a new properly supportive mattress suited to your needs.
- Short-term temporary double stacking can act as a placeholder bed while an old mattress is replaced. But this shouldn't be permanent.
Overall, for sustained great sleep and spinal health, keeping just one properly supportive, high-quality mattress is the way to go. Layering in a mattress topper for added comfort is safer than stacking two whole mattress units.
Make the Best Mattress Choice for Your Situation
While it may seem expedient to get added height and softness from combining two mattresses, this double-stacking practice often causes more trouble than it's worth.
Voided warranties, premature wear, lack of support, and hygiene issues make permanent mattress stacking inadvisable. Still, short-term stacking can work as a temporary placeholder.
Ultimately, investing in a supportive, comfortable mattress tailored to your preferences, plus a topper if desired for extra softness, is the ideal move for restful sleep. Be sure to rotate your mattress seasonally to promote even wear.
Does your mattress currently feel uncomfortable or do you need an upgrade? The best solution is to find a replacement mattress designed specifically to provide the right support and comfort for your body and sleep style.
With high-quality materials and construction on just one properly designed mattress, you can avoid the need to stack two mismatched beds.
