Mattresses that may be shipped to your door are really handy.

The buyer may have to wait before sleeping on their new mattress. Until they can unpack at their new place, or until the renovations are finished, the mattress must remain in a box in the corner.

In today’s article, we’ll discuss the optimal storage duration for a memory foam mattress. Also, the dangers of procrastinating unpacking will be brought to the attention of the readers.

Why Shop Online for a Mattress in a Box?

In order to answer the question “How long is it good to leave a memory foam mattress in a box?”, it’s important to first explain why someone would want to buy a mattress online rather than in a store. After example, wouldn’t it be easier to have a full-size mattress shipped to you instead of worrying about the potential damage caused by leaving a compressed one?

One major advantage of bed-in-a-box sets is their portability. Even a luxurious, multi-layered mattress (like the ones we’ve shown here) may be folded up and stored in a compact box nowadays. If this were available, it would be a great convenience for apartment dwellers who shop.

A further justification is the fact that online mattress shops typically provide better deals. And these days, it’s really not that unsafe to order a bed on the internet. An in-home demo is standard on most models. That’s why customers enjoy low prices, no-hassle returns, and convenient shipping.

When Is the Best Time to Unpack a Mattress?

Most mattress companies advise removing the packaging as soon as possible, or at the latest within the first 72 hours. This is the most risk-free choice, so consumers can avoid any harm. It’s also easier to see manufacturing flaws in the mattress if the customer unpacks it right away.

This would also give consumers more time to try out mattresses in stores. The customer can return the mattress for a full refund and choose a new mattress if they find it isn’t comfy. Simply said, there wouldn’t be any needless delays in getting to sleep if the mattress were unrolled and placed on the bed right away.

By the way, shoppers often exchange mattresses for a firmer model, as not all models labeled “firm” actually feel supportive enough. In case any of our readers require a particularly strong mattress, we have assembled a collection of really firm options for them to choose from.

How Long Can You Keep a Mattress in a Box?

Not all mattresses that claim to be “firm” are equally supportive, therefore many customers return them in search of a firmer option. In case any of our readers are in need of a very supportive mattress, we have compiled a collection of models that fit that bill.

The answer is conditional on the make and model of the bed being considered. The time frame typically lasts anything from one week to three months. The best course of action is to call the mattress manufacturer and ask how long you should wait to unbox it.

The Casper mattress, for instance, is designed to withstand being compacted in a package for up to three months without compromising its integrity. Additionally, the Purple mattress, to give one example, can remain in its box for up to two weeks. Some lightweight mattresses (here’s more info on that) are designed to stay flat in a box for a few of months. To avoid the mattress from becoming too compressed in the box, it is best to notify the provider beforehand.

Risks of Keeping a Mattress in a Box

While there may be times when it’s necessary, storing a mattress in a box for an extended period of time can have unintended repercussions. Those things could be:

  • Damage. The answer is obvious here: memory foam mattresses shouldn’t be folded up for extended periods of time. They need to expand in a way that takes into account the density differences between their many levels. The foam’s cradling and adaptable capabilities may degrade if it is stored in a box for an extended period of time. Specifically, foams of lower density may lose thickness with time. Therefore, after swelling, the mattress could feel different. Inevitably, this can lead to a significantly less pleasant sleeping experience than anticipated.
  • Constraints on growth. It’s possible that foam that has been compressed for a long time won’t fully expand. The mattress may also expand uniformly while the corners stay flat. This can have an impact on the ease with which a person sleeps.
  • Deficiencies in the warranty system. Since material damage from being compressed for an extended period of time is a possibility, this might also render the manufacturer’s guarantee null and void. Customers are responsible for any issues arising from the mattress, including but not limited to customer discomfort and/or broken foams.

Consumers should exercise caution as they remove the mattress from its packaging (especially when cutting the plastic wrap). Puncturing the mattress cover can void the warranty. This could also cause the fiberglass to escape into the air (a fire barrier commonly used in memory foam mattresses). Inhaling fiberglass dust is risky, and once it settles on furniture, it’s nearly impossible to remove. So, shoppers need to handle scissors with extra care. Memory foam mattresses that do not contain any fiberglass are also an option.

8 Benefits of a Memory Foam Mattress

#1 Ideal for all sleeping positions

As a quick reminder, customers should use extreme caution when unboxing mattresses (especially when cutting the plastic wrap). If the mattress cover is punctured, the warranty may be nullified. This may also lead to fiberglass particles dispersing into the atmosphere (a fire barrier commonly used in memory foam mattresses). It’s not good to breathe in fiberglass dust, and once it settles on your furniture, it’s nearly impossible to get rid of. Therefore, cautious use of scissors is advised while shopping. As an additional precaution, there are memory foam mattresses that do not contain any fiberglass.

#2 Superior motion absorption

A further significant benefit of modern memory foam mattresses is their reduced motion transmission. Memory foam is great for couples since it can absorb energy and reduce the impact of movement. The other person in the relationship doesn’t feel a thing when one of you rolls over or flops around.

#4 Less back and neck pain

Viscoelastic foam encourages a neutral spinal posture, allowing for a more relaxed and supported night’s sleep. Problems associated with persistent neck and back discomfort are alleviated over time.

#5 Hypo-allergenic

An allergy sufferer’s best friend is a memory foam mattress. Mold and mildew are not able to grow on polyurethane foam, and neither can dust mites or pet dander.

#6 Good pressure relief

Having a mattress that is excessively firm might cause pain in the hips, shoulders, and knees. This issue is remedied by the fact that memory foam evenly distributes weight over the sleeping area.

#7 Customized support

In the past, memory foam had a bad rep for making people too hot while they slept and feeling like they were sinking into quicksand. Newer types allow for more air circulation, keep you cooler at night, and let you choose your own firmness level, among other benefits. There are now memory foam mattresses available in a range of densities, from the lowest to the highest, and in a variety of foam comfort thicknesses.

#8 Sag free and no sinkage

Modern memory foam mattresses are built from high-quality adaptable materials that strike a nice balance between being too soft and too stiff. The open cell construction of this mattress guarantees that it will retain its shape for the duration of its useful life.

Memory Foam Mattress Do’s and Don’ts

If you put in the time and energy to maintain your memory foam mattress, it will reward you with years of the ideal combination of softness and support.

In order to preserve the quality and appearance of your mattress, follow these easy dos and don’ts:

1. Do Rotate It Regularly

Contrary to many other multilayer foam mattresses, our memory foam mattresses are not meant to be flipped over. It is recommended that you switch the orientation of the mattress every three months or so to avoid depressions from forming in high-use areas.

2. Don’t Get it Wet

Do your best to prevent liquids from getting on the surface of the mattress, since this might speed up the deterioration of the foam. If you tend to be a spiller, a mattress protector is a must-have for your bed!

3. Do Use a Suitable Bed Base

The bed’s base should be solid, level, and free of any large gaps. Slats on the base should be between 10 and 15 centimeters broad, with gaps of no more than 5 centimeters. Over time, the mattress will wear down faster if the gaps are too big. Here you may learn how to determine if a certain bed frame will work with your mattress.

4. Don’t Keep it Near Strong Heat Sources

Due to its heat-sensitive nature, Memory Foam conforms perfectly to your unique body shape. Therefore, you should avoid placing your memory foam mattress near any sources of extreme heat.

In the same vein, using electric blankets or hot water bottles on a memory foam mattress is not recommended because the intense heat from these items might compromise the mattress’s performance and even its structure over time.

5. Do Protect it With a Washable Mattress Cover

Most of our mattresses include a cover that can be removed and washed to keep it clean and safe from spills and stains. Wash at 40 to keep your mattress spick and span for longer.

6. Don’t Make Your Bed!

How do you Deep Clean a Memory Foam Mattress?

Accidental spills and stains are unavoidable. If you ever need to give your mattress a thorough cleaning, try these methods:

  • To get rid of dust, remove the sheets and vacuum the mattress with the brush attachment to get rid of dead skin and dust mites.
  • First, clean the mattress, and then sprinkle baking soda over it and let it sit for 24 hours to absorb any lingering odors. After this time has passed, you can vacuum the baking soda out of your mattress and enjoy your brand new bed!
  • Dishwashing liquid with water or white vinegar in a spray bottle makes for a greener alternative to scrubbing out stains. Sponge the soiled area with some cleaning solution and spray the area to be cleaned. When stains persist after spot cleaning, sprinkle baking soda on the mattress.

Does a Memory Foam Mattress Need to Breathe?

Yes. Mold may be avoided and a comfortable temperature can be maintained all night long with proper ventilation. Bed frames that have a low profile and allow air to circulate under the mattress are preferable.

How Do You Fix A Dip in a Memory Foam Mattress?

It’s possible that your present memory foam mattress is beginning to droop or dip because it’s constructed of low-quality foam and you haven’t been rotating it as often as recommended.

Once the mattress has begun to sag, your only options are to replace it or add a mattress topper, such as one made of memory foam, for increased comfort. Take good care of your mattress and you won’t have to worry about a thing!

Wrapping Up

It goes without saying that a mattress should be removed from its packaging as soon as feasible. It’s not always the best course of action, though. Consumers should keep in mind that various mattresses have varying “unpacking due dates” before making a purchase. You should always check with the manufacturer to find out how long a compressed mattress may be stored without suffering damage.

So, what exactly is holding you from removing the plastic from your brand new bed? Can I use it right now, or do I have to wait a certain amount of time? Leave your thoughts in the feedback section below!
