Thick mattresses are suitable to use with standard-size sheets so that you can find linens and other bed accessories that fit. They add height to your bed, revamping any room's look and feel. Less likely to cave in, they will provide ideal support, even after prolonged use. Thick mattresses have a solid design, making them more durable and able to sustain more weight. However, these thick mattresses are harder to get into and out of. They can be pretty heavy, so flipping and transporting them will require at least two people. Also, they have poor temperature control, trapping heat and making it warmer at night.

Need Some Help Narrowing Down Your Options? Here's Some Additional Information to Know:
The Comfort Scale
Firm Mattresses

If you're considering a firm mattress, a Fenix thick mattress might be a good choice for you. These mattresses feature a 34-36 pound indentation load deflection ranking and are ideal for individuals who sleep on their back. Improving circulation, they promote deeper sleep. They distribute your weight properly, supporting your joints as well as other vulnerable areas. One downside is that these mattresses might be uncomfortable if you're not accustomed to sleeping on hard surfaces, so it can take a couple of days to get used to them. Also, they can put painful tension on specific pressure points, including the shoulders and hips.

Medium Firm Mattresses

If you're trying to find a medium firm mattress, a Fenix thick mattress might be a good choice for you. These mattresses deliver proper weight distribution to support your back and joints and other sensitive areas. Suitable for couples, they are designed to accommodate couples with one person who likes to sleep on their side and the other on their back or stomach. They are ideal for individuals who sleep on their back and sides throughout the night and have a 29-31 pound indentation load deflection rating. Something to consider is that medium firm mattresses can become lumpy or sag with extended use, making them less comfortable and supportive since your body won't be aligned well.

Plush Mattresses

If you're considering a plush mattress, a Fenix thick mattress might be a good choice for you. These mattresses are built with an indentation load deflection rating of 19-21 pounds and are ideal for those who usually sleep on their back, sides, or stomach. These contouring support mattresses adjust to your body shape for superior comfort. Providing additional support, they are great for those who suffer from back problems or joint pain. However, these plush mattresses can become lumpy or sag over time, so it's likely that they'll be less comfortable and supportive since your body won't be aligned well. Also, they may be problematic if different people will be sleeping in the bed, causing the surface to sink if there is a significant difference in weight.

Understanding How to Select the Right Size for a Fenix Thick Mattress
King-Size Mattresses

Debating whether you need a king-size mattress? Read on to get to know some of the facts. These mattresses are suitable for couples, offering plenty of space for you to move around. They measure 76" X 80" and are ideal for master bedrooms. Something to consider is that they are large and heavy, making them hard to transport and flip. In addition, they are not ideal for small areas, since they can make the area look somewhat cluttered. Take a look at this awesome Fenix thick mattress if a king-size mattress is what you need.

Full-Size Mattresses

If you're looking for a full-size mattress, the comfortable Fenix thick mattress could be right for you. Full-size mattresses are suitable for couples, with a cozy fit between the two sleepers. They fit in studio apartments and measure 54" X 75". Something to consider is that they are short in length, so if you're taller than 6'3", then you might want to consider a longer bed. Additionally, they have a narrower sleeping space, so you will have limited space to move when sharing your bed with another person.

Queen-Size Mattresses

Looking for a good queen-size mattress? The comfortable Fenix thick mattress might be right for you. Queen-size mattresses are suitable for couples, offering sufficient space for two people. They measure 60" X 80" and are ideal for master bedrooms. However, they are smaller compared to king-size mattresses, so if you like having a wider sleeping area, you should consider upgrading to a larger mattress. On top of that, they are not great for spaces with limited room, so if you live in a small house or apartment, you might want to think about getting a smaller bed.

Choose the Right Fenix Thick Mattress for You
Gel Memory Foam Mattresses

If you're thinking about getting a gel memory foam mattress, this Fenix thick mattress could be a good choice. Gel memory foam mattresses are made with various materials, giving you a wide range of foam densities to choose from. They provide pressure-point relief by supporting the most sensitive areas of the body. They have a breathable design, which helps circulate air, keeping them in good condition over time. They provide even weight distribution, so they prevent sinking from occurring. They feature superior motion isolation technology, so restless sleepers would benefit from these mattresses.

Memory Foam Mattresses

If you're thinking about getting a memory foam mattress, this Fenix thick mattress might be a good choice for you. These mattresses offer pressure point relief, helping to ease pain in your joints, so you will wake up feeling refreshed. They are built with various foam types, providing the cushion you desire. They have superior motion isolation, which is great for people who move a lot when sleeping. Something to keep in mind is that they can smell a bit like chemicals initially, so you'll have to air them out for at least 24 hours before adding sheets. In addition, they aren't waterproof, so any encounter with moisture can cause degeneration and reduce their usable life.

Latex Hybrid Mattresses

If you're thinking about getting a gel memory foam mattress, this Fenix thick mattress might be a good choice. Designed to provide the optimum balance of firmness and softness, these mattresses add a balance of firmness and softness and prevents them from sinking as time passes. Designed to dissipate heat instead of absorb it, they will enhance sleep quality by keeping a cool and comfortable body temperature. They have various types of coils, so you can choose between firm to plush comfort. They feature a breathable design, which extends the lifespan of the mattress by enabling air to circulate freely. They are designed with low VOC materials, which do not release harmful chemicals. They have superior motion isolation, which is great for people who move a lot when sleeping. Something to keep in mind is that they are not easily available, so you'll have to do a lot of searching online in order to find it. In addition, they are hard, so if you prefer a softer mattress, this might not be the best choice for you.
