How To Break In A Mattress?

How to Break in a Mattress: An In-Depth Guide

When you first purchase a new mattress, it may not feel as comfortable as you imagined right out of the box. This is because a new mattress needs time to break in, allowing it to conform to your body’s shape and improve in comfort. Generally, breaking in a mattress can take anywhere from a few weeks to a couple of months. In this guide, we will explore various tips and methods to help you break in your new mattress effectively and enjoy a good night’s sleep as soon as possible.

The Adjustment Period

Your new mattress and its materials need time to adjust to your body. When you first lie down on a fresh mattress, the materials such as foam, springs, or latex are still firm and can feel quite different from what you are used to. This adjustment period is essential for both the mattress and your body. Over time, the mattress will start to mold to your sleeping position, providing better support and comfort.

During the first few weeks, you may experience a different level of comfort each night. This period can be compared to breaking in new shoes; it might feel stiff and uncomfortable initially but will become cozy and well-fitted as you continue to use it.

Sleep on It Regularly

The simplest way to break in a mattress is to sleep on it regularly. Consistent use will allow your body weight and movements to soften and shape the mattress over time. Even if the mattress feels a bit uncomfortable at first, make it a point to sleep on it every night. Your body’s natural heat and pressure will work to soften the materials and make the mattress more comfortable.

If you find it difficult to sleep on the new mattress due to initial discomfort, try spending additional time on it during the day. Lounging or sitting on the mattress while reading a book, watching television, or working on your laptop for a few hours can also help speed up the break-in process.

Apply Even Pressure

Another effective method is to distribute your weight evenly across the mattress. You can achieve this by walking or crawling on it gently. Make sure to cover all areas of the mattress, not just the spots where you usually sleep. This will help soften the materials uniformly and prevent certain sections from becoming overly soft while others remain firm.

Keep in mind to avoid jumping or putting excessive pressure on the mattress, especially if you have invested in a high-end memory foam or latex mattress. Extreme pressure can damage the internal structure or could void your warranty.

Maintain Proper Support

It’s important to ensure your new mattress is properly supported. A good foundation or bed frame can enable the materials to break in evenly and support your weight adequately. If your mattress is on an uneven or old frame, it may not break in properly, potentially causing discomfort and reducing its lifespan.

Make sure to check with your mattress manufacturer for specific recommendations on the type of foundation or bed frame that is best for your mattress. Proper support will not only help in breaking in your mattress but also extend its durability.

Keep the Room Temperature Moderate

Room temperature can play a significant role in the break-in process, especially for mattresses made of memory foam or other materials that react to heat. Memory foam, in particular, tends to be firmer in cooler conditions and softer in warmer temperatures.

Try to keep your bedroom at a moderate temperature, around 68-72°F (20-22°C). This can help in making the mattress more malleable and quicker to adapt to your body shape. Using an electric blanket or heating pad for a short period before you sleep can also help to soften the mattress, but avoid keeping them on for long durations as it might affect the mattress’s quality.

Rotate Your Mattress Regularly

Rotating your mattress every few weeks during the first three months can help in breaking it in evenly. This practice is particularly crucial for mattresses that are designed to be used on both sides. By rotating the mattress, you ensure that it wears uniformly, which can help prevent the formation of indentations and prolong its lifespan.

To rotate your mattress, turn it 180 degrees so that the head of the mattress is now where your feet go. This technique will help the mattress adjust to different pressure points and provide balanced support.

Use a Mattress Topper

A mattress topper can serve as an additional layer between you and the firm surface of a new mattress. Not only does it add immediate comfort, but it also helps in easing the break-in process. Mattress toppers come in various materials, including memory foam, latex, and feather-filled options, so you can choose one that best suits your initial comfort needs.

However, keep in mind that continuously using a thick mattress topper might slow down the break-in process. Therefore, it’s a good idea to remove it occasionally to allow the mattress to adapt to your body directly.

Top 5 Mattresses Recommended By

Avoid Heavy Items

Avoid placing heavy objects on your new mattress for an extended period. Items such as heavy boxes, furniture, or even pets can create pressure points that might lead to uneven wear. If you need to store items on your bed temporarily, ensure they are light and distributed evenly to prevent damaging the mattress material.

Clean Your Mattress Properly

While breaking in your new mattress, it’s crucial to maintain cleanliness to ensure its longevity. Dust, sweat, and other particles can accumulate over time, affecting the material’s quality and comfort. Make it a point to clean your mattress regularly, following the manufacturer’s care instructions.

Vacuuming the mattress surface can help remove dust and debris. Spot cleaning with a mild detergent and water can help remove stains. Additionally, using a mattress protector can prevent dirt, spills, and other contaminants from affecting the mattress during the break-in period.

Understanding the Mattress Materials

Different mattresses have different break-in times and methods, largely depending on the material they are made from. Here is a brief overview of various mattress types and what to expect during the break-in process:

Memory Foam Mattresses

Memory foam mattresses are known for their unique ability to conform to the shape of your body. However, they typically require the longest break-in period. Initially, the memory foam can feel quite firm. By keeping the room temperature moderate and using your body heat and weight regularly, memory foam can start adjusting to your shape within a few weeks.

Innerspring Mattresses

Innerspring mattresses, which include coils or springs, usually break in faster than memory foam. The coils in these mattresses provide immediate support but need some time to adapt to your specific pressure points. Using the mattress regularly and rotating it can help in breaking in an innerspring mattress efficiently.

Latex Mattresses

Latex mattresses are highly durable and can be slightly firmer initially. They respond quicker to body weight and heat compared to memory foam. When breaking in a latex mattress, regular use and moderate room temperature can help speed up the process. Rotating and applying even pressure across the surface can also be beneficial.

Hybrid Mattresses

Hybrid mattresses, which combine coils with foam or latex layers, can have a varied break-in period depending on the type of materials used. The foam or latex might take some time to soften, while the coil system can adapt more quickly. By following general break-in practices like rotating, regular use, and applying even pressure, you can help a hybrid mattress break in properly.

What to Avoid During the Break-In Period

There are certain practices that you should avoid during the break-in period to ensure your new mattress remains in optimal condition:

* **Jumping on the Mattress:** While gentle pressure can be beneficial, jumping or applying excessive force can damage the internal structure.
* **Using a New Mattress Protector Immediately:** Some mattress protectors can make the surface feel rigid. Consider waiting a few weeks before using one or opt for a stretchable protector that doesn’t impede the break-in process.
* **Ignoring Discomfort:** If you’re consistently uncomfortable after the initial break-in period, don’t ignore it. There might be an issue with the mattress itself or it might not be the right fit for you. Most mattresses come with a trial period, so make sure to take advantage of it.

Finishing Thoughts

Breaking in a new mattress is a crucial process that requires patience and consistent use. By understanding the materials of your mattress, maintaining proper support, applying even pressure, and taking care of it regularly, you can hasten the break-in period and enjoy the comfort and support that your mattress is designed to provide.

Remember, the perfect mattress doesn’t feel perfect right out of the box. It grows with you and adjusts to your body’s unique needs over time. Embrace the break-in period, take steps to ensure even wear, and soon enough, your mattress will become the cozy, restful sanctuary you envisioned. Happy sleeping!
