Memory Foam vs Spring Mattress: A Fight to the Death

By Callie Paige

2 men arm wrestling

It’s time for the ultimate battle.

We’ve stuck memory foam in the ring with a spring mattress to see, once and for all, which one comes out on top.

It can feel overwhelming trying to pick out a mattress when there’s so many out there, all with competing advertising claims. Buying a mattress is an important investment, and it’s vital you make the right choice for your sleeping needs.

Here at Sleep with Sid, we’re pretty serious about mattresses. That’s why we’ve come up with the pros and cons for each type of mattress, so you can make an informed decision.

You’ve read the reviews. We’ve done the research. It’s time to find a champion.

Memory foam vs spring mattress: This time it’s personal.

Support and Comfort

Probably the most obvious thing to consider when choosing a mattress is which is the comfiest. You don’t want your mattress to be rock hard or softer than a marshmallow. It’s finding the sweet spot that’s key.

Let’s compare the contenders:

Muscle Man Memory Foam

Memory foam’s signature move is its ability to soften in contact with body heat, moulding to your shape to provide tailored support and pressure relief for your body.

If you’re a side sleeper, memory foam provides even support and weight distribution, cushioning pressure points like your hips and spine. This is especially helpful if you suffer from joint pain.

The Spring Slayer

Spring mattresses usually offer firmer support than memory foam with a bouncy feel. The thicker the spring, the less give it allows for. If you tend to stay in one position throughout the night, you might find a spring mattress tough on your pressure points.

Side sleepers may also struggle to find proper spinal alignment on a spring mattress, leading to back pain and soreness. These days however, lots of spring mattresses are covered in a layer of foam to sidestep the issue.

Durability and Stamina

Like any great wrestler, a good mattress needs to have the stamina to last the fight. A mattress is an investment and you want to get the best value for your money.

Ding! Ding! Time for round two:

Mad Dog Memory Foam

A quality memory foam mattress should last you a good 15 years (and we give you a lifetime guarantee!). Although memory foam can grow softer with age, if you pump for a higher quality, hybrid foam it should stand the test of time. Generally, the denser the foam, the more durable it is.

Swing and Slice Spring

In theory, a spring mattress is strong and should be long lasting. However, this is hindered by the spring mattress’ biggest weakness...

The dreaded sag.

Over time, your body weight carves uncomfortable troughs and valleys into the mattress, making that elusive good night’s sleep even harder to come by. On average, you’ll need to replace a spring mattress every 3-10 years.

Mattress Maintenance Needs

Like a boxer after a fight, a mattress needs a little TLC to stay in tip top condition. You don’t want anything that demands too much work, but there are simple ways to prolong your mattress’ lifespan.

Macho Memory Foam

For memory foam mattresses, it’s best to switch the head to feet direction every three months to prevent permanent body impressions. 

The Spring Strangler

A double-sided spring mattress typically needs to be flipped every three months to avoid sagging.

Motion in the Ocean

When you’re sharing the ring, try not to step on your opponent's toes.

But what about sharing a bed? You might want to consider movement absorption when choosing a mattress, especially if you’re a restless sleeper. Even in a King size, tossing and turning can really affect sleep.

The Memory Foam Masher

The density of memory foam means it’s an excellent movement absorber. Great news if you’re sharing with a partner.

The Spring Smasher

Not so good news for spring mattresses if you have a fidgety bed mate. The lack of weight absorption and squeaky springs are a bad recipe for a peaceful night’s sleep.

Turning up the Temperature

Like the most fearsome of opponents, memory foam has a bad rep when it comes to heat.

But reputations can be deceiving.

The Memory Foam Mauler

Some people dismiss memory foam due to its heat retaining properties which can result in a stuffy night’s sleep. However, memory foam has moved on from its early days in the ring. With new, open cell technology, memory foam of today keeps air circulating.

At Sleep with Sid we have a wild card up our sleeve.

Introducing Graphyx to the ring!

Graphyx is a featherlight opponent to heat, with super conductive skills to draw heat from the body all night long. A 3.5cm thick layer of Graphyx just beneath the comfort layer draws heat down into the lower layers of support foam to keep things breathable.

Spring the Destroyer

A regular spring mattress shouldn’t have much effect when it comes to body heat. However, if it’s covered with a foam top layer this could affect the temperature, so it’s worth checking the quality of the foam before making any decisions.

Solid as a Rock

It’s tricky to compare firmness between two types of mattresses made of very different materials.

Let’s let them fight it out in the ring:

The Memory Foam Monster

As mentioned prior, memory foam is dense - great for defeating your enemies.

Choosing the right density for you depends on your body weight and your sleeping preferences. Indentation Load Deflection (or ILD) tells you how firm the memory foam is.

The higher the ILD rating, the more firm it will be. Something at around 30 ILD is medium firm.

Spring the Soul Crusher

The firmness of a spring mattress depends on the thickness of its coils which are measured in gauges (the higher the gauge, the thinner the coil). Thinner coils feel softer and are better able to shape themselves to your body.

Generally though, spring mattresses feel harder than foam.

Fighting off Allergens

For those sensitive to allergens, your choice in mattress can really make a difference to the quality of your sleep.

The Mighty Memory Foam

The high density of memory foam makes it almost impossible for dust mites to break through the barrier or for mould to set in. These are two of the most common causes for allergy outbreaks and eliminating these will help you on your way to undisturbed sleep.

The Spring Stomper

A spring mattress is an allergy sufferer’s worst nightmare. The inner coils provide a cosy home for dust mites and dead skin cells to accumulate, causing mould to grow in the cavities.

In terms of allergy busting, The Spring Stomper is completely annihilated by The Mighty Memory Foam.

Who Wins the Trophy?

While the spring mattress put up a good fight, in the last few moments, memory foam delivered the final, brain busting blow with its spinal support, motion absorption and hypoallergenic moves.

The ultimate champion however, remains the Sid mattress, a pioneering memory foam mattress engineered to give you the best night’s sleep you’ve ever had.
