Have you been feeling like you’ve been sinking deeper into your mattress than you’d like, or feel like your bed is too soft and squishy for comfort? Our sleep preferences and bodies can change over time, so your mattress that felt just right when you first bought it may feel a little too broken in for comfort a few years later. Before you consider dragging your mattress to the curb — keep reading. We’ll help you determine whether you need a firmer mattress, and will give you some tips and tricks to upgrade the bed you have to make it more firm and supportive.
Why You Might Need a Firm Mattress
There are several reasons you may need a firmer bed:Sleeping Position
If you sleep on your back or stomach, you’ll need a firmer mattress to keep your back in a neutral position overnight. If your mattress is too soft and you sleep in one of these positions, your midsection could sink uncomfortably far into the mattress throughout the night which can place extra pressure on your lower back.Back Pain
Firm mattresses help prop your back up in a healthy posture. Soft beds can allow your joints or other areas of your body to push too far into the bed, which can create pressure and disrupt your natural spinal alignment.Mattress has Broken in Over Time
After years of use — especially if you sleep with a partner and pets — even the highest quality beds will eventually start to break down. If your bed is sagging and no longer supports you, you may want to look for a new mattress. You could, however, possibly get a few more years out of your bed if you take steps to make your mattress firmer.A New Sleep Partner
If you like a plush, fluffy bed, but your partner needs a more sturdy sleeping surface to stay comfortable, you’ll need to meet somewhere in the middle. A split king bed could be a good option if it’s in your budget — but if not, you’ll need to adjust your current mattress so you both can stay comfortable.Why Mattress Firmness Is Important
Mattress firmness plays a huge factor in your quality of sleep — and overall health and well-being. You need a bed that is an appropriate firmness level for your body type, sleeping position, and personal preferences to promote a healthy spinal alignment and prevent potential pains from popping up as you sleep.The Right Mattress Firmness for You
The right mattress firmness depends greatly on your sleeping position. Here are some of the most popular sleeping positions and the firmness levels that suit them:- Side sleepers tend to need a softer sleeping surface to cradle the hips and shoulders as they sink into the bed. Firmer beds can create pressure in these areas and cause aches and pains.
- Back sleepers usually prefer a bed that is a medium-firm firmness level — fairly firm, but still soft enough so it has gentle give that can conform to the natural shape of your body. This helps keep the body supported without putting pressure on your curves.
- Stomach sleepers usually need a firm mattress. In softer beds, your hips can sink deeply into the mattress, which can put your spine out of alignment and cause back pain.
- Combination sleepers typically sleep best on a medium-firm bed. This middle-of-the-road firmness level suits most sleepers and body types, and isn’t so soft that you feel stuck in a doughy bed as you try to change sleeping positions.
Mattress Thickness
It is also important to consider mattress thickness. A thicker mattress is made of taller layers, which can help prevent sinkage. This extra support is especially helpful for stomach sleepers or those with heavyweight body types. See our mattress thickness guide to find a bed with an ideal thickness for your sleep needs.How to Make Your Mattress Firmer
If a new mattress isn’t in your budget, try these tips to fix up the bed you have.Check Your Trial Period
Most mattresses come with a sleep trial period that is typically between 30 and 365 days. If you are within your sleep trial period and your bed is still in a good condition, you may be able to swap out your bed for a firmer model at no or a low cost.Look at Your Warranty
If your mattress is still under warranty, your overly-soft bed may be eligible for a repair or replacement. Some mattress companies will cover the damage if layers are worn out or your body indentations are very deep.Rotate or Flip Your Mattress
If you sleep in the same place on your bed and sleeping position every night, your bed may start to get soft and saggy in that area. You can rotate your bed every few months to help limit the amount of wear on your bed to keep it feeling firm and supportive. You can also flip some mattresses — but make sure to check with your mattress manufacturer to make sure this will help.Inspect Your Box Spring or Frame
If you have the wrong type of bed foundation or are resting your mattress on an old, broken, or worn-out foundation — your mattress may be sagging and feel softer than it actually is. Tighten and fix up your bed frame if it’s looking sub par. If you can’t fix it, you may need to just replace your bed frame to get the support you need.Add Plywood
Adding a plywood board beneath your mattress is a cheap and easy fix to help add some firmness to your bed. This mattress firmness hack adds support to your foundation and adds another layer of firm support to your mattress.Get a Mattress Topper
Adding a mattress topper to your bed is like adding an extra layer of support, and there are mattress toppers available that are designed to make your bed firmer. As an added perk, these toppers can also add durability and cooling features to your mattress.Move Your Mattress to the Floor
If your mattress feels too soft on a foundation and you’ve exhausted all other options, you can consider placing it directly on the floor to sleep on. Make sure your floor is clean to avoid exposure to allergens and dirt. Also — keep in mind that putting your mattress on the floor can void some warranties that require your bed to be used with specific foundations.Make Bedding Flat and Tight
Extra bedding can make your mattress feel softer. Use thin bedding and tuck it tightly into your mattress to avoid creating extra fluff if you want a firmer feel.Watch the Thermostat
Some mattresses, like memory foam, can be affected by temperature. Changes in temperature make the mattress materials expand and contract, which can compromise the level of support and make the bed feel less firm. If your bedroom is warmer, then your bed will feel softer. We recommend you keep your bedroom between 60 and 72 degrees.Keep Your Mattress Dry
Humid weather conditions and sweaty nights can make your mattress damp over time. Damp mattresses tend to get softer and squishier. If your mattress is feeling a little soggy, try drying it out outside in the sun and keeping it wrapped in a moisture-wicking mattress cover and sheets.How To Know When To Replace Your Mattress
When your mattress is too soft, you’ve had it for a while, and nothing you try will make it more comfortable, it might be time to replace your mattress. Even the most high-quality mattresses will break down over time. You may want to start shopping for a new mattress if your bed has visible signs of wear and tear, like lumps or sagging, or you’ve been sleeping on it for more than five years and noticed you’ve started waking up feeling sore. If you decide to go this route, don’t forget to shop sales and recycle your current mattress if you can.The Best Firm Mattresses

We were skeptical of buying a mattress on line but it could not have gone any smoother. Anthony answered all of our questions during our many phone conversations. Delivery was prompt and went without a hitch. Best of all the mattress is so comfortable! I haven’t had such a good night sleep in years. Highly recommend this.
