Most of us spend nearly 8 hours lying on the bed every day. After a tiring working day, everyone deserves a comfortable and peaceful sleep to refresh their minds and recharge their bodies. This makes it essential to have a mattress that not only provides comfortable sleep but also supports your back, spine alignment, and pressure points. Choosing a cheap mattress just to save some money can cost you uncomfortable sleep, physical discomfort, body aches, and even some severe neck and back problems that require a doctor to cure. With an array of mattresses present in the market today, choosing the ideal one that fulfills your requirements and preferences is tough. Costco is a well-known retail mattress brand renowned for providing high-quality mattresses at reasonable prices while ensuring great value. Whether you are a regular shopper or a first-time customer, this guide will provide you with the information you need to buy the right Costco mattress according to your preferences. 

Research before Buying

Before purchasing a mattress, it’s crucial to understand various things like the different types of mattresses available, mattress sizes, their pros and cons, their features, qualities, etc. This helps you decide which one is most suitable for you according to your sleep preferences and medical conditions. There are 4 basic mattress types that include Innerspring, memory foam, latex, and hybrid. Further, there are variations of these mattresses with slight changes or modifications that you can choose according to your specific needs, such as back pain, motion isolation, allergies, hot sleep, etc. Costco mattresses are available in 6 different sizes: Twin, twin XL, Full, Queen, king, and California king. You can choose the one according to your weight, height, leg space required, number of people sleeping, luxury, comfort, room space, etc. 

Consider your Sleeping Position

Choosing the right mattress that aligns with your sleep position is crucial to avoid back problems and discomfort. To ensure that, check whether you prefer to sleep on your back, on either side, or on your stomach, and based on that, choose the specific Costco mattress. If you sleep on your back, you need a mattress that provides enough support to your neck, shoulder, and torso and keeps them in perfect alignment. If you sleep on the side with a pillow, you require a mattress that provides support and contour to your body shape. Lastly, if you are a stomach sleeper, you should opt for a mattress that can provide firm support and not sink too much.

Select the Right Firmness Level

For most people, firmness is the most crucial aspect when selecting the ideal mattress. The firmness of the mattress depends on individual preferences and sleep positions. For the back sleeping position, medium to medium firm mattresses like medium firm foam or hybrid mattresses will work best. If you are a side sleeper, a soft to medium soft firm mattress like memory foam is the best choice as it molds your body and relieves pressure points. A firm innerspring or foam mattress is an ideal choice for you if you are a stomach sleeper.  

Understand your Sleep Problems

The majority of people have sleeping problems that cause them to wake up during the night due to discomfort. Such problems include sleeping hot, restless sleep, motion isolation, allergies, snoring, etc. Choosing a mattress that prevents such problems and enables you to sleep comfortably is crucial. If you sleep hot or reside in an area with a hot climate, avoid overly plush mattresses, as they can hold the body heat and cause overheating. Instead, go for a mattress with coils and springs as it promotes proper airflow and circulation. Also, if possible, try to get a mattress with gel foam or latex which can provide a cooling effect. However, if you are a restless sleeper, which comes in the category of a combination sleeper, choose a mattress that provides ample space for tossing and turning. For allergies, use a hypoallergenic mattress and pillow covers. 

Set A Budget

No matter how good the mattress is, if it is out of your price range, you are unlikely to buy it. Therefore, it’s important to determine your budget – how much you are willing to spend on the mattress. It helps you narrow down your options and choose the one that fits your budget range and does not cause unnecessary financial strain. Costco offers a variety of mattresses of different price ranges; therefore, you can easily find the one that not only aligns with your preferences but also fits your budget. 

Check Costco’s Selection Online

How Safe is Online Shopping

It is always beneficial to buy a mattress from a physical store so that you can test it by lying down on it and assess its comfort and support. However, it’s not possible to check every mattress that fits your requirements. Therefore, check the costs, features, qualities, customer reviews, pros and cons, etc., of the mattress online before heading to the store. This helps you compare prices in advance, make a list of mattresses to choose from, and save time in the shop.

Consider Motion Isolation

If you share your bed and sleep with a partner, selecting a mattress with high stability and good motion isolation is crucial. Good motion isolation prevents disturbance on one side of the bed due to movement on the other side. This feature is essential, especially if one individual is a restless sleeper who frequently tosses and turns during the night.  

Evaluate Edge Support

How We Determine Edge Support Ratings

Evaluating edge support ensures that the mattress maintains its shape and provides proper support when sitting at the edge. This reduces the chances of falling from the bed and provides a sense of security, which leads to a stress-free sleep. To check that, roll to the edge of the bed and see if you are stuck in the corner or about to slide off. This is beneficial, especially if you sleep at the edge or have kids at home. 

Conclusion

Costco is one of the most popular retail mattress brands that provide high-quality mattresses at low prices. Using the above tips, you can make the right selection and choose the mattress that not only fits your budget but also provides the most supportive and comfortable sleep. At last, check the return policy, understand the trial period, negotiate the price and inspect the mattress after its delivery to your home.
