Can You Sleep on a New Mattress Straight Away Information

As much as you want to enjoy your new bed straightaway, sleeping on a memory foam mattress too soon can have some consequences. First of all, the off-gassing can be uncomfortable to sleep with because of the unpleasant smell. Second, it’s still in the process of airing out to fulfill the expansion in 24 hours.

However, sleeping on your new mattress without waiting for the 24 hours is technically okay. Most memory foam mattresses can reach 90 percent of expansion in 4 to 6 hours after you unroll it. There are some things that manufacturers want you to know before sleeping on a new mattress right away, check out the following:

  • Memory foam mattresses are shipped by compressing it inside a small box. This slows down the expansion time, hence you need to allow it some time to fully expand. And this process usually takes up to 24 hours to finish.
  • When you wait for 24 hours before using your new memory foam, you avoid damaging the foam as it expands. This prevents customer dissatisfaction and potential refunds or replacements.
  • Allowing the foam to expand for 24 hours can help you eliminate the off-gassing smell without affecting your health. Remember, off-gassing contains chemicals or VOCs in the memory foam that can be toxic for you.

Now, are you willing to wait for the recommended expansion time before sleeping on your new mattress? Using a mattress which has not fully expanded yet will only give you an uncomfortable experience.

What to Do with a New Mattress

Once you received your new mattress, it’s important to consider some practical tips to help it expand more quickly. One of the best ways to make sure that you will have a good night’s sleep with your new memory foam is to let the off-gassing finish first. Then you need to wait until it expands to the exact inches that is indicated in the box.

If your memory foam has a 10-inch profile, you should wait until it has completely expanded with corners in full shape. You may only put the sheets and mattress cover once the bed has reached 10 inches in height. Before you sleep on it, the corners should have taken shape to avoid damaged or distorted mattress.

The following are some expert suggestions to speed up your new memory foam’s expansion process:

  • Place it in a room with higher temperature. Heat is important in helping new mattresses to expand more quickly. A cold room will only stiffen your new mattress and cause longer time to fully expand. Therefore, cranking the heat in your bedroom slightly is a huge help in the process.
  • Roll on your mattress to help the foam expand more. This doesn’t mean that you need to sleep on your new mattress right away. Applying some weight on the memory foam can speed up its expansion process. Just make sure you don’t overdo it to prevent damaging the foam.
  • Give it enough space to expand. Make sure to place your new mattress somewhere it can enjoy plenty of space and ventilation while expanding. More room means quicker expansion than the expected time. You can put it in your spare room, on the floor, or in an open space.

Whether you’re using gel mattress or regular memory foam, proper care is important in the longevity of the product. Follow these tips to ensure that your new mattress will last longer than your previous one.

How Long Can You Leave a Memory Foam Mattress in the Box

You can leave your memory foam mattress in the box for up to two months depending on the brand. Longer than that and it will become permanently damaged. Remember, the foam is tightly compressed and rolled in the packaging to make shipping more convenient. If you have a Zinus mattress, it can be kept in the box for a week, Casper mattress for 3 months, and Emma mattress for 4 weeks.

How Long Do You Let a New Mattress Air Out

New mattresses may take between 24 to 48 hours to air out according to most manufacturers. However, this is not guaranteed as mattresses are made of various materials, thickness, and firmness. Some memory foam mattresses tale more time to expand than other products. If you’re lucky, your new mattress may take less than 24 hours to completely air out.

More importantly, you can sleep on your new mattress straight away. But this might give you an inconvenient experience while sleeping, especially if the foam hasn’t expand much yet. The key here is to allow at least 4 to 6 hours for your mattress to air out so that you can at least have a comfortable sleep.


The decision is solely up to you if you’re going to sleep on your new mattress on the same day the package has arrived. A new memory foam may perform at its best if you use it right away. If it doesn’t expand fully within 24 hours, allow more time to help it become in shape. Your new bed may not be as soft or as firm as it should be on the first night, but rest assured that it will eventually come in full shape.
