5 Inch vs. 8 Inch Mattress: How to Choose

Key Takeaways

• - Key Differences in Thickness and Construction: 5-inch mattresses are compact and low-profile, ideal for kids or lightweight sleepers, while 8-inch mattresses offer enhanced comfort with additional layers for better support, cooling, and durability.

• - Comfort and Support: Thicker mattresses (8-inch) provide better pressure relief, body contouring, and weight distribution, making them suitable for average to heavier sleepers. Thinner mattresses (5-inch) are supportive but better suited for occasional use or lighter individuals.

• - Durability and Cost: 8-inch mattresses are more durable and long-lasting, making them a better investment for everyday use. In contrast, 5-inch mattresses are budget-friendly and practical for guest rooms, bunk beds, and trundles.

• - Choosing Based on Needs: Consider factors like sleeping habits, bed frame compatibility, and budget. Thicker mattresses are ideal for long-term use and comfort, while thinner ones are great for affordability and specific furniture setups.

 

Thickness is a key factor to consider when choosing a mattress. Beyond your bed height, mattress thickness impacts comfort, support, and even the longevity of your mattress itself.

 

If you've narrowed your options to a 5-inch mattress or 8-inch mattress, you might be wondering about the differences and which one best fits your needs. Don't worry, we're here to guide you through the nitty-gritty details to make your choice stress-free.

 

Key Differences Between 5-Inch and 8-Inch Mattresses

The thickness of your mattress affects everything from how it feels to how long it lasts. Here's how 5-inch and 8-inch mattresses stack up.

 

Thickness and Construction

At first glance, the most obvious difference between a 5-inch and 8-inch mattress is, of course, their thickness. Digging deeper, though, you'll find that the construction of each type varies slightly. Take Plank+Beam's mattresses as an example:

 

• - 8-Inch Mattress: This mattress features three carefully crafted layers. The top is a perforated memory foam comfort layer that provides a plush, comfy feel. The middle AirFlo foam layer keeps you cool all night (goodbye, night sweats!). Finally, the dense foam base layer gives you the support to keep your spine aligned through the night.

• - 5-Inch Mattress: Don't be fooled by its slim profile. The 5-inch mattress isn't just a thinner version of its 8-inch counterpart. While it has similar memory foam and AirFlo foam layers, it also includes a super-thin support layer specifically designed to compensate for its lower height.

 

These materials ensure that both the 5-inch and 8-inch mattresses provide the best comfort-support balance. The difference lies in how each mattress feels, performs, and fits into your space.

 

Comfort and Support

The most obvious question when comparing mattresses of different thicknesses is, "Does it feel different?" The short answer? Yes.

 

More thickness often means better pressure relief and body contouring – two key factors for restful sleep. Whether you're lying on your back, side, or stomach, a mattress that's 8 inches thick helps distribute your body weight more evenly. This weight distribution can be especially important for people with joint pain or anyone looking to reduce pressure points.

 

While slimmer mattresses like the 5-inch mattress don't offer quite as much cushion, they still deliver solid support, particularly for kids or lighter adults.

 

Durability and Longevity

Mattress thickness also plays a role in durability. Over time, thinner mattresses can wear out faster due to less material to absorb weight and motion.

 

The thicker design extends the lifespan of an 8-inch mattress, making it a wise choice for those looking for a longer-lasting solution.

 

While thinner mattresses can wear down more quickly, this might not be a big issue if they're for occasional use (like a guest bed or trundle).

 

Cost Differences

It's no surprise that thicker mattresses often come with a higher price tag. Added materials and durability drive up the cost. However, it's worth considering how much value you'll get for your investment.

 

Lower in price, 5-inch mattresses are a go-to choice for budget-conscious buyers who don't need the durability of a thicker mattress.

 

While thicker mattresses can be pricier, they're a long-term option, ideal for everyday use and comfort.

 

 

 

 

Who Should Choose a 5-Inch Mattress?

If you're eyeing a compact, low-profile mattress, you're not alone. Here are some common scenarios where a 5-inch mattress shines.

 

Ideal for Children or Lightweight Sleepers

A 5-inch memory foam mattress can be a perfect match for kids or lighter-weight individuals. With less weight to distribute, the mattress's thinner layers still provide adequate comfort and support without sacrificing quality. Plus, it keeps the sleep surface lower to the ground, making it practical and safe for kids.

 

Best for Low-Profile Bed Frames

Whether you're outfitting a bunk bed, loft bed, trundle bed, or daybed, a low-profile mattress ensures a good fit. 5-inch mattresses maximize both guardrail height and headroom on loft and bunk beds for adults. Plus, they make trundles easier to slide in and out. Thinner mattresses also won't overwhelm the design of compact furniture, like low-profile platform beds.

 

Budget-Conscious Buyers

If affordability is top of mind, a 5-inch mattress delivers comfort without breaking the bank. Slim mattresses are typically lower in cost while still providing a cozy sleeping surface. Plus, this can be an excellent way to stay within budget if you're furnishing multiple rooms.

 

 

 

 

 

Who Should Choose an 8-Inch Mattress?

Need a mattress that's a bit more "extra?" The added thickness of an 8-inch mattress makes it a versatile pick for many sleepers.

 

Better for Average or Heavier Sleepers

If you have an average or higher body weight or simply prefer extra cushioning, an 8-inch mattress provides the comfort and support you need. Its thicker design helps absorb weight without bottoming out, meaning you can wake up refreshed and ache-free.

 

Suitable for Everyday Use

For mattresses that see daily use, opting for the thicker profile of an 8-inch mattress just makes sense. Its added durability ensures it stands up to wear and tear better than a 5-inch option.

 

Greater Comfort and Pressure Relief

If you're someone who values premium comfort, this mattress thickness ticks all the boxes. From enhanced body contouring to pressure-point relief, the thicker structure provides a supremely cozy surface you'll sink into.

 

Additional Factors to Consider When Choosing Thickness

Still on the fence? Here are a few extra things to keep in mind before deciding between a 5-inch and an 8-inch mattress.

 

Intended Use of the Mattress

Is this mattress for your primary bed or a guest room? Occasional use for trips or overnights might call for a 5-inch mattress, while everyday use leans toward an 8-inch option.

 

Bed Frame and Platform Compatibility

Not all bed frames can support thicker mattresses, and thinner mattresses may not work well without the right base. Be sure to double-check compatibility to avoid warping or sagging.

 

Aesthetics and Room Design

A low-profile mattress can add a sleek, minimalist feel to your bedroom. It pairs well with minimalist bedroom furniture, such as a platform bed. Additionally, thinner mattresses are best to maximize your visible headboard height.

 

On the other hand, a thicker mattress provides a cozier, more traditional aesthetic. Consider the dimensions of your headboard and overall bed frame before choosing a mattress thickness.

 

 

5-Inch vs. 8-Inch Mattress: Which Is Right for You?

Still undecided? Break it down by weighing these key considerations:

 

Consider Your Sleeping Habits

Are you a side sleeper who loves a soft, cushy surface? Or perhaps a back sleeper who prefers firm support? Thicker mattresses like an 8-inch memory foam design often provide more versatility for different sleeping positions.

 

Think About Longevity

If you're looking for a long-term investment, a thicker mattress offers increased durability and retains its shape better over time.

 

Evaluate Your Budget

Both sizes can be excellent options depending on how much you're willing to spend. Find the balance between affordability and quality that works for you.

 

And don’t forget—10-inch mattresses are a popular choice too, offering even more comfort and support. Curious how they compare? Check out our blog on 8-inch vs 10-inch mattresses to learn more.

 

FAQs About Thin Mattresses

Can a 5-inch mattress provide enough support for adults?

Yes, particularly for lightweight individuals or for occasional use, a 5-inch mattress can still deliver comfort and support.

 

Are 8-inch mattresses suitable for bunk beds or trundles?

It depends on the bed frame's design and clearance. Ensure your bunk bed's guardrails are at least 13 inches tall before choosing an 8-inch mattress. Additionally, ensure the mattress allows enough room to sit on the bottom bunk. For a trundle bed, an 8-inch mattress may make it harder to stow away the pullout bed, so a thinner mattress may be a better choice.

 

How does mattress thickness affect sleep quality?

More mattress thickness often means better spinal support, body contouring, and pressure relief. However, the "best" thickness depends on your comfort needs and sleeping habits.
