Best Firm Innerspring Mattresses: The Support You Need

Soft, contouring, and comfortable surfaces should be reserved for the first few inches of the mattress and can be achieved via a wide variety of material options that most mattress manufacturers offer.
Mattresses that contain an innerspring are often considered the firmest overall due to their more rigid construction designed for durability, and long-lasting wear. This includes hybrid mattresses that are built-in layers around an innerspring core to provide various comfort needs.

How Firmness is Defined
The term firmness, in and of itself, is not defined as a hard surface, but rather the overall feel of a surface when you sleep on it. Subjective to your body shape, size, and weight, what you perceive as soft may be denser and less forgiving to another person. Despite that, mattress companies provide an idea of this sleep surface comfort based on how their mattresses are constructed.
Most mattresses are built in layers, and offer a surface option generally made from various types and densities of foam and soft material padding. Beneath you will most likely find a transition layer that sits upon a more firm base- made of heavy foam or innerspring options.
Mattresses that boast an innerspring core are amongst the most solid, or firm, and long-lasting since they are built from a material that does not compress or wear down easily under pressure. This support influences the layers stacked upon it and helps create an overall more solid surface than other types of mattress core materials.
Despite that, it’s not as if you would be sleeping on a hard-topped surface. Those top layers offer a huge range of comfort to pick and choose from to help cushion your joints and provide the feel you prefer.
How to Determine Your Firmness Level of Comfort
The firmness level of comfort is often broken up onto a scale that ranges from 1 to 10, with lower numbers expressing a softer experience, and high numbers related to a more solid, or firm feel. Rarely are the extreme low or high numbers ever used, with most mattresses falling somewhere between 4 and 7 as a firm mattress core is important for body support.
Numbers below 5 will have more sink and contouring, and provide less overall support, whole numbers above 5 won’t be as contouring on a whole, but will provide the uplift needed for the majority of body types. Firmer choices are best for back and stomach sleepers as well to help align the spine, while an uplifting, but the responsive surface is generally a side sleeper’s choice to allow for the shape of the hips and shoulders.
Firm Mattress Benefits
Firm mattresses are considered quite healthy for all body types and sleep positions. Check out the many benefits a firm choice provides:
• Supports Back, Neck, and Joints
You can never have a TOO firm surface, but you can have a too soft surface. Soft surfaces may feel comfortable initially, but are unable to support your body properly and when you wake with aches and pains, this is due to your muscles and tendons in flex as it struggles to align your spine through the night. If you feel your mattress is more solid than you prefer, you can always add a topper to help cushion the experience without sacrificing the support.
• Aligns the Spine
A firm choice keeps your spine in alignment and helps allow your body to relax. Spinal alignment is crucial for a healthy night’s sleep and provides better blood flow that disseminates nutrients and oxygen through your body for healing purposes.
• Creates Proper Weight Distribution
Your body weight is not evenly distributed, and you need a mattress that won’t cave under the bulk of your body weight to create an uneven sleep surface. If your mattress is too soft, it will create an uneven sleep surface, misalign your spine, joints, and muscles.
• Helps Influence a Deeper Rest
Sleeping in alignment with the proper support allows full body relaxation and keeps you from tossing and turning. This in turn provides a deeper, more healing and restful night.
