Choosing a Good Mattress Under $300 


Temperature is essential to consider when you are purchasing a mattress within the best price range. A lot of mattresses now have a number of features that help to control temperature. These include the use of advanced foams in the construction of the mattress, phase change materials which help to dissipate your body temperature and natural ventilation. All of which work to give you a comfortable, relaxing night's sleep. They help to avoid overheating, a common cause of poor quality, broken sleep.


A mattress with poor support will be your back’s worst enemy, resulting in crippling back pain over some time. A good mattress will conform to your body shape, while also keeping your spine in alignment.

Motion Transfer 

This is often overlooked when purchasing a mattress. Yet it really should be a key consideration, especially if you share your bed with a partner. A mattress which doesn’t have a motion transfer minimizing feature will result in you getting broken sleep. Who likes to be woken up every time your partner moves or gets up?


This is usually the most important factor that people consider when purchasing a mattress. The key here is lying on a mattress and getting a feel of it before you purchase it. A mattress that is too soft will likely have poor support. On the other hand, a mattress that is too hard will lead to more pressure on your body, possibly leading to reducing blood circulation or even nerve cinching.

A mattress with medium firm support will usually suit the majority while offering reasonable comfort. Hybrid mattresses are a good choice for those who aren’t a fan of a full memory foam mattress but still want the support that memory foam offers. These hybrid mattresses have a foam layer on top of the traditional spring mattress layer.

Edge Support 

This is particularly important if you prefer to sleep near the edge of the bed. A foam encasement within the boundaries of the mattress will offer optimal comfort as opposed to steel rods sometimes found in cheaper mattresses.

When Should You Get A New Mattress? 

Getting a good night's sleep is essential to maintaining a good quality of life and avoiding daytime tiredness and fatigue. There are some medical conditions which can result in poor sleep. But having a poor-quality mattress can also lead to a night of tossing and turning, resulting in less than ideal sleep.


Research has indicated that the lifespan of a mattress is roughly 8 years. So if your mattress is older than this, this is one of the first signs that it is probably time to replace it. Cheaper mattresses can have a shorter life span as they wear and tear faster. More expensive mattresses can have a longer lifespan. Ultimately, no mattress is designed to last forever.


Another big sign that it's time to buy a mattress is if it is starting to sag and is indented with the shape of your body. Sagging occurs in all mattresses as the springs break down over time. Memory foam mattresses also sag over time, and this leads to a "hammock" effect. A sagging mattress will result in aches and an uncomfortable night's sleep.


You might think your mattress is comfortable. Unfortunately, many people just get used to the feeling of discomfort that they don't actually realize that their mattress is uncomfortable, especially for stomach sleepers. It may be a sign that you need to replace your mattress if you get a better night sleep while in a hotel or staying with a friend.

Aches and Pains

Another sign you might need to replace your mattress is if you are constantly waking up with aches and pains, especially back pain that goes away as you stretch out and go about your day.

Research has shown that a medium firm mattress is best for combating chronic pain in the lower back. A good mattress should offer you a pain-free sleep whether you're a back, side or one of the less common stomach sleepers.

Dust Mites

Mattresses can become a prime ground for dust mites which build up over time. This will especially affect those with allergies. If you're experiencing symptoms out of allergy season with no other explanation, you may need to replace your mattress to combat the problem.

Weight Changes

Significant weight loss or gain can also change how effective your mattress is for you. Your mattress might also become less adequate if you have gone from sleeping alone to sleeping with a partner as it may not be able to cope with the added extra weight.

Is It Best to Buy It Online? 

A mattress needs to be tested for firmness and comfort before buying. This is the advantage of visiting a physical store as you can try out the mattresses first. You can always try the mattresses in the store and then look for one with the same Indentation Load Deflection, used for measuring firmness online. Some online retailers will also offer a money-back guarantee if the mattress is not comfortable enough for you.

There is often an advantage to buying online, especially for those on a tighter budget. You can often save some money by buying directly from the manufacturer online. This removes the retailer who often charges more than the manufacturer to make a profit. By removing the middleman, you should be able to get a mattress at a better price.


Having a good quality mattress is key to getting a night of good quality sleep which is essential for an optimal quality of life. There are plenty of good mattresses on the market for under $300.

There are so many options these days from mattresses with a high-density base to mattresses with layers of foam. Look for a reputable brand mattress that is more likely to last you between 7-10 years; one that will offer you optimum comfort through the years.
