Overall LUCID Gel Memory Foam Mattress Review
If you are looking for the best mattress under $300 for a younger individual, such as an older kid or a teen (or if you happen to be an older kid or teen yourself!), then this is just the mattress you’re looking for. It is designed to be a little smaller, with available thickness levels capping with the 10-inch gel-infused mattress options.
The inclusion of the gel-infused memory foam is a key factor, as the temperature regulation capabilities are likely to be a handy feature for younger individuals, particularly if they are the energetic types that produce plenty of body heat. If you are a parent, this mattress will truly shine in the summertime as you won’t have to deal with your kids struggling to get enough sleep, allowing you to enjoy the school holidays without moody little ones spoiling the fun!
My only complaint about this item is its short, 3-year warranty, as many brands can outclass this duration, and I feel a warranty would be important for a kid’s mattress, as they are likely to be rough and cause damage. Nevertheless, the quality of this product is irrefutable, with high regard for its stretch, comfort, and sleep quality, making it a great choice for your new mattress.
This gel memory foam mattress by LUCID has received an average of 4.6-star ratings on Amazon reviews from over 3700 customers who have validated its features through first-hand use. Definitely consider this brand for your new mattress, as the ratings simply do not lie with this one. For heavier individuals, I recommend looking at the LUCID 10-inch gel-infused mattresses.

I think we can all agree that the best feature here is the massive 20-year warranty, a superb length of time that you likely won’t need to use.

Luxurious ventilated refreshing gel particles are infused into a memory foam mattress to provide a cool sleep that leaves you feeling refreshed and rejuvenated upon waking.

Overall Signature Design by Ashley Chime Memory Foam Mattress Review
If you are like me and were startled at the concept of a “green tea” foam layer, I assure you that you will learn to be both intrigued and excited about this new mattress technology. Made using green tea extract, this layer of foam actually provides an array of health benefits that improve relaxation and sleep. The green tea mattress remains fresher for longer while eliminating odors and promoting sustainability and eco-friendliness.
There are a couple of downsides with this mattress from Signature Design by Ashley Chime, and that is the significantly shorter warranty of 1 year, which isn’t a great deal, to be honest. On the other hand, if a short warranty is not a huge deal-breaker for you, you might get ahead of the game with this mattress as it has some advantages that simply cannot be attained by most brands.
To further verify its quality, we have a very strong 4.6-star rating to reckon with, which is an absurdly high score when you realize this average was taken from a ridiculously high quantity of people, almost reaching 35,000 Amazon reviews. I know that might sound far-fetched for a mattress, so I don’t blame you if you aren’t convinced, and that’s why I am providing the facts and evidence with the link here for you to verify!

Overall Molblly Memory Foam Mattress Review
Molblly has produced a solid mattress here, which I feel is best suited for the average-sized person, regardless of their mode of sleep. With multi-layered foam that combines to support temperature regulation, comfort, and ventilation, this mattress covers all the essentials to provide a good night’s sleep, but that’s not all!
A conveniently designed zip-off cover is the perfect icing on top as it allows you to regularly wash the most important part of your mattress, the top layer in which your body resides. Additionally, the specialized foam layers reduce motion transfer from your partner if you are sharing the bed with another individual.
It is indeed the ideal mattress for a couple, and I recommend purchasing this in the queen size for your new mattress, as the benefits are optimal in this range. Almost 6000 Amazon reviews have highly praised this product for sleep quality, value for the price point, and softness, boasting an average of 4.5-stars for a highly commendable item. The comments are overwhelmingly positive, with a few on the nasty side too, but I’ll let you decide which side of the fence you want to be on by providing the following link to Amazon reviews

Mattress Buying Guide: What to Look for in a Mattress
In this section, I will be guiding you through the key elements to look out for when purchasing mattresses to better understand for yourself which is the best mattress online.
Price
If you are on a budget, then it may be best to look for the best mattresses under $300, such as the ones included in this review. However, I urge you not to consider price as a factor if you can help it, as investing in a good mattress will do wonders for your quality of life (remember, one-third of your life is spent sleeping!), so the price point can always be justified.
Sleeping position
It is important to know which sleeping position you are most comfortable with, as mattresses can offer different benefits for stomach sleepers, side sleepers, and back sleepers. I would recommend going for mattresses that are designed to support all types of sleeping positions, as you never know if your mode of sleep may change over time.
Support
Understanding your personal needs is vital to selecting mattresses, as you want to ensure that you are getting the right amount of support. If you are a heavier individual, I would recommend innerspring mattresses or a hybrid mattress that incorporates an innerspring, as this provides an extra edge of durability and firmness.
Motion Transfer
This is an important one if you sleep in a shared bed with a partner or other, as it ensures that their movements do not create ripples in the bed that could adversely affect your sleep. Most memory foam mattresses are built to counter this, but I recommend ensuring that “motion transfer prevention” is included in the description; otherwise, contact customer support to verify this.
Comfort
While most memory foam mattresses are comfortable by nature, you may want to ensure it includes a layer of specially designed comfort foam to give it that extra edge.
Temperature
If you struggle with sleep on hot summer nights or are generally sensitive to temperature changes, make sure to look for mattresses infused with cooling gel for temperature regulation. This will ensure that heat is drawn away from your body and your mattress does not heat up during sleep.
Edge Support
Do you find yourself constantly sliding off your mattress during sleep? This is an issue that is solved with edge support mattresses. Look out for mattresses with edge support if this is a problem for you (I know it is for me!), and never worry about sliding off the edge of your bed again!
Firmness level
This comes down to personal preference ultimately. However, I believe that heavy individuals benefit the most from more firm mattresses, as they prevent you from sinking too low into the mattress. I recommend hybrid mattresses of innerspring and memory foam for the heavier person, as it provides a medium-firm mattress that is both comfortable and durable.
Mattress Types
Innerspring
Innerspring mattresses consist of many individually wrapped pocketed coils built-in to the mattress to give it an extra bounce that stops you from sinking. It also provides greater durability and is often used in hybrid mattresses in conjunction with memory foam.
Hybrid
As mentioned, the hybrid mattresses consist of innerspring and memory foam combined into one, resulting in comfortable, firm, and durable mattresses that are particularly suitable for heavier people. When buying a mattress, it’s important that you know what features you need to give you the necessary support to select the correct type of mattress.
Foam
Foam or memory foam mattresses are the most comfortable type of mattress due to their body-contouring properties that mold to your body’s shape and relieve pressure during sleep. Other types of foam to look out for include high-density foam which is often used as the base, and gel-infused foam, usually used in the middle or as the top foam layer.
Latex
These mattresses are a little different from memory foam and specialize in their breathability and ventilation due to an airflow-type design. I recommend these types of mattresses if you find the memory foam mattresses too claustrophobic or suffocating.
The Best Mattress Under $300
My top pick for the best mattress under $300 goes to the Sscecretland by Molblly hybrid mattress. This item combines innerspring with memory foam to provide an unbeatable sleep that encompasses durability and comfort. The innerspring memory foam type hybrid mattresses are rare to find, and this brand truly does not fail when it comes to providing support for the heaviest of people, so you can cut out any signs of discrimination with this one!
All-in-all, buying a new mattress is no walk in the park, and there are so many things to consider, such as durability, material, structure, individual sleeping preferences, mattress cover, and so much more! To find the best mattress for yourself, really get to know what you are after, and have a good look at our reviews to understand the good, the bad, and everything in between when it comes to mattresses under $300. Good luck and all the best with your mattress shopping!
