Q: Can a vacuum packed mattress be rolled up and stored away again?

A: Vacuum packing a mattress correctly, without damaging it, requires a large compressing and vacuum packing machine. Once the mattress has been removed from its airtight packaging it cannot be vacuum packed in the home. It will also be too large to roll back up. Mattress toppers can be rolled up and stored away.

What Happens If You Sleep on a Memory Foam Mattress Before 24 Hours

So you’ve got a new memory foam mattress, you’re excited – in the back of your mind you remember some rule of thumb about waiting for a day before sleeping on it. The manufacturers say to wait for at least 48 hours before it expands fully, especially the ones that are still in the box. But if you’re curious what happens if you sleep on a memory foam mattress before 24 hours, then you’re in the right place.

Sleeping on a Memory Foam Mattress Too Soon

There are some essential things to consider before sleeping on a memory foam mattress too soon. For instance, most memory foam mattresses require up to two days before it goes back to its original size and form. After all, these mattresses are vacuum sealed, pressed and rolled tightly to fit in the packaging.

But can you sleep on a memory foam mattress the first night? Well, you can relax, jump, or do whatever you want with your bed as soon as you received it. Using it right away won’t cause any damage but will only speed up the process of expanding the foam.

This 24-hour recommendation is to ensure customer satisfaction and manufacturer guarantees.It also gives any off-gassing time to dissipate.

Why It Needs 24 Hours to Expand?

Well firstly, you you should know that the off-gassing happens in the first couple of hours. If it’s okay to sleep on your new memory foam without waiting for 24 hours to allow it to expand, then why do we still need 24-48 hours?

It’s all about the manufacturer guarantee. They claim that if it doesn’t fully open up and you did sleep on it then you’ll void that guarantee. If you’ve paid several hundred or even thousand on a new bed – you have to think twice about risking your money back opportunity.

But another important question is that, what should you do if your mattress takes more than 24 hours to expand fully? Well, there are rare cases wherein compressed memory foam mattresses don’t fully extend. If that’s the case, then you can ask your seller what to do to make it expand or ask for a new one.

Zinus Mattress – How Long to Expand

Most Zinus Memory Foam Mattress like the 12 Inch Green Tea Mattress need 48 to 72 hours to relax and decompress and restore to its original shape. That’s why the Zinus company manual advice customers to open the packaging within 72 hours of arrival to make sure the mattress they ordered will fully grow to its potential.

And with the green tea extract infuse in the foam, you will not inhale hazardous and harmful smell with you first open the packaging. It will typically dissipate after laying the mattress in a well-ventilated area.

What to Do When Memory Foam Mattress Not Inflating?

Memory foams have different thickness levels. You can choose from an 8-inch mattress to a 13-inch memory foam bed. They are designed with open cells to conform to various shapes of sleepers using the bedding. Before they leave the factory, these mattresses are folded and compressed using a machine roller to fit into a small package.

The best way to use a memory foam is to let it expand before using. However, if it’s not inflating, there are simple tricks you can do to enjoy its comfort after 24 hours of arrival. Check these tips to help you out:

  • Unbox the memory foam within the three days of arrival. Remove the plastic cover using your hands. Never use any sharp objects like a knife and scissors when removing the mattress from the package to avoid damages.
  • Allow the foam to adjust in room temperature, which may take up to a couple of hours until it begins expanding. This step is essential, especially when you get your memory foam in the winter season. Foam mattresses tend to become more brittle if it’s still tight, which can lead to tearing.
  • Unroll it in a spare room so the open cells of the memory foam will expand and inflate freely. Separate each layer of the foam carefully to allow them to grow. Pull them in uniform motion with slow and steady hands.

What Are the Possible Reasons Why your Lucid Memory Foam Mattress is Not Expanding?

If your Lucid memory foam mattress is not expanding, there might be an essential step you haven’t performed after unrolling it. First, it needs time to develop, typically within 72 hours before you can finally use the mattress. So wait for it until it becomes entirely usable in its original size.

Some memory foam mattresses take one week to air out, but they lose the new-foam smell at the same time. It is already fully plumped when you noticed that the smell is gone. And you can use a mattress topper to retain the plumpness of your new memory foam.

Key Takeaways

The truth is, each mattress has its own expansion time and features. Therefore, the time required before they fully expand will depend on the model and brand you purchased.

Before you can move it to your bedroom, most memory foam mattresses that usually take 24 hours to decompress may still need at least two hours. Waiting for 24 hours or 72 hours to allow a bed to expand is a traditional belief.

Most of the mattresses offered on the market today only take a short time to decompress, and you can sleep on the right after unboxing them. So there’s nothing to worry about sleeping on your mattress too soon. You won’t damage your memory foam while sleeping on it during the first night.

The key is in the type of memory foam used in your mattress. The higher quality the foam, the better and faster it will expand in less than 24 hours.

How Do I Take My Mattress Out of the Box? When Can I Sleep On it?


To open your Avocado Green Mattress:

  1. Move the box to the room where you’ll ultimately want your new mattress.Because we use natural materials (which weigh more than polyurethane foams), you may be surprised by how heavy your new mattress is. When moving it, especially the larger sizes, the work is best done by two people.
  2. Open the brown shipping boxat the top within two weeks of receiving your mattress. Your mattress will be sealed inside within two layers of plastic.
  3. Slide the mattress out of the boxby laying the box on its side.
  4. Find the edge of thewhite layer of plasticand begin to unrollthe outer white layer of plastic only, and remove it from the mattress. The mattress will still be sealed within a second layer of plastic.Do not cut both layers of plastic at the same time, or the mattress will immediately begin to expand while rolled.
  5. Unroll the mattressand position it — either on the floor or on your bed frame — in a spot where it has ample room for it to expand to full size.
  6. Finally, carefully cut the remaining clear layer of plastic and remove it from the mattress.The mattress will fill to full size rather quickly (but not in any dangerous or alarming way). Call in friends and family members, as this is especially fun to watch. Within 30 minutes, you can lie on your new mattress. Within a few hours, your mattress will be fully expanded.

Roll-Up Mattresses: Everything You Need to Know

Here at Mattress Online, we’re often faced with the question, "how are roll-up mattresses different to regular mattresses?", so we thought it was time to address the question. And guess what? We have all the answers. So let’s get this ballrolling!

How are mattresses rolled up?

To understand how roll-up (also known as vacuum-packed) mattresses work, we first need to know how something so big can fit in a box!

Well, these mattresses embark upon a journey where they are:

  1. Placed in a protective bag
  2. Flattened in a compression machine
  3. Vacuum- and heat-sealed
  4. Rolled using a tumbler and sealed again

Don’t worry, no mattresses are harmed in this process!

Here’s a video to explain how the roll-up process works:

How to set up a roll-up mattress

Here’s what to do to get your roll-up mattress back to its original size and ready for a great night’s sleep:

  1. Unpack your roll-up mattress and roll out to full size
  2. Place your mattress on the bed of your choice
  3. Allow your roll-up mattress to expand slowly. It does this by replacing the sucked-out air, gently returning to its original size

. Your mattress is now ready for you to sleep on it!

Roll-up mattresses: how long do they take to expand?

Although most roll-up mattresses will expand within an hour, they usually take up to 8 hours to be ready for use. Aspects such as fillings and size all affect the amount of time it takes a roll-up mattress to expand. In some circumstances, mattresses can take up to 24 hours to regain their original shape.

Roll-up mattresses: do they smell?

Roll-up mattresses may come with a slight smell when first unpacked for two potential reasons:

  1. They are often made using synthetic fillingsThese can give off a slight smell when first used.
  2. A fire retardant substance is usedTo meet regulations and ensure a safer mattress.

As you can imagine, these smells can build up within a vacuum-sealed bag. But don’t worry – they generally disappear within 24-48 hours. Open the windows and keep your bedroom well-ventilated during this time.

What is memory foam?

Memory foam is a revolutionary material which was developed by NASA for the space program to give astronauts additional support during take-off and landing. High density memory foam, like that used in our mattresses, was developed for use in the bedding industry because of its amazing pressure relieving ability. Memory foam reacts with the heat of your body, moulding to your body shape and giving you ultimate support and comfort for a really great night’s sleep.

How are memory foam mattresses made?

Dormeo memory foam mattresses have a layer of high quality visco-elastic memory foam on the very top of the mattress. This provides comfort and support right where you need it. The memory foam layer is supported by a thicker layer of Dormeo’s patented Ecocell foam, which provides additional support for the body and works in conjunction with the memory foam to draw away heat and moisture from the sleep surface throughout the night. This core is wrapped up in a luxury Italian designed and manufactured cotton cover for the ultimate in comfort.

What will memory foam do for me?

Memory foam provides a very comfortable and supportive sleeping environment, free of allergens and dust mites. If you haven’t slept on a memory foam bed before, or if you are upgrading to a Dormeo mattress from another memory foam bed, you can be confident in the quality and value that Dormeo memory foam mattresses provide. You’ll get comfortable faster, fall asleep quicker, sleep deeper for longer and wake up feeling fully refreshed.

Will memory foam help with my back pain?

Dormeo mattresses are ideal for sufferers of back pain, because the comforting memory foam moulds to the shape of your body, relieving pressure points and spreading the weight across your whole body. Memory foam mattresses are known the world over to provide excellent support for the back and neck. They allow better spine alignment while you sleep and reduce the number of uncomfortable pressure points you sometimes experience with other mattresses. Whilst we cannot guarantee or make any specific claims as to the health benefits of Dormeo memory foam mattresses, we do know that they give a very comfortable and supportive night’s sleep.

Is memory foam hot?

Dormeo memory foam mattresses have been specially designed to keep you cool all night long. Our researchers have spent years perfecting the perfect combination of foam layers in the Dormeo memory foam mattress for just this purpose. Dormeo’s own patented Ecocell foam which supports the memory foam layer has a remarkable open structure with millions of breathable pores that allow air and heat and humidity to be drawn away from the sleeping surface whilst you sleep, to keep you cool and fresh all night.

Is a memory foam mattress good or bad for dust mites and other allergens?

Memory foam naturally repels dust mites and is not a source of allergens like other mattresses. Feathers, horse hair and sprung mattresses all provide environments which have excellent living and breeding conditions for dust mites and over time allergens and dust mites numbers in these mattresses can become very large indeed. With memory foam, the structure and density of the foam keeps dust mites away providing a cleaner and more hygienic bed for the best possible night’s sleep.

Are your memory foam mattresses delivered rolled and vacuum packed?

Yes, all our Dormeo memory foam mattresses are vacuum packed and rolled before they leave our manufacturing facility in Italy. We have found that not only does this have a positive environmental impact, because we can use fewer lorries to transport the same number of mattresses, but that it is also the most hygienic and convenient method of delivery for our customers. The mattresses haven’t been touched by anyone else before you open them, and when you get them into your home you can easily carry them to your bedroom before opening them. The process of rolling and packing the mattresses does not cause any damage to the mattress in any way.

How do I open my memory foam mattress when it arrives?

When your Dormeo memory foam mattress is delivered simply take it to the room of your choice and then carefully open the plastic cover with a small knife or pair of scissors. Please take care only to cut the plastic and not to damage the cotton cover of the mattress when opening it.

What happens when I unpack my memory foam mattress?

When the plastic cover is pierced, this allows air back into the mattress. Very quickly, usually within 15 minutes, the mattress will have recovered its original shape. We always recommend you allow 6 hours for the mattress to fully regain its shape before covering it with sheets and sleeping on it for the first time.

Does my memory foam mattress require turning?

Your Dormeo memory foam mattress does not require turning like other mattresses. Because the memory foam layer is on one side of the mattress, we just recommend rotating the mattress head to toe every two weeks.

I’ve heard memory foam mattresses can be smelly – does Dormeo smell?

Some rolled mattresses sometimes have off-gassing, however this is very rare with the quality of Dormeo products and if there is any smell this normally dissipates very quickly. If the smell persists, we would suggest airing in a well-ventilated room for 24/48 hours. If following this there is still a smell please contact us and we can discuss the next steps.

Why does memory foam change colour over time?

This is a simple result of the natural oxidization process and happens with all memory foam mattresses. It does not affect the performance or feeling of the mattress in any way.

Can I try your mattresses before I buy?

To keep our memory foam mattresses at the best possible prices for our customers, we currently only sell our mattresses via and through other carefully selected online retailers. But we do offer a unique 60 night risk-free trial on all our memory foam mattresses, which means that we will refund or exchange your mattress after 60 nights with absolutely no quibble, if you are not happy with it. So why not try it for yourself in your own home, and we’ll take the risk for you?

Why is the guarantee so long?

We rigorously test all our memory foam mattresses to ensure that they will provide the same comfort and support for a very long time with normal use. Our confidence in the quality of our products is reflected in the guarantees which we can offer, 15 years on our memory foam mattresses, and 6 years on our other mattresses.
