How To Raise Mattress On Platform Bed: Practical Ways To Add Height and Support

If you’re searching for “How To Raise Mattress On Platform Bed”, you’re probably looking for simple, safe ways to make your bed higher, more comfortable, or easier to get in and out of. This guide walks through the most common methods, what to watch for, and how to keep your mattress supported and secure.

Why Would You Want To Raise a Mattress on a Platform Bed?

People look up how to raise mattress on platform bed for a few main reasons:

  • The bed feels too low for easy entry and exit.
  • They want more storage space under the bed.
  • They prefer a taller, more traditional bed height.
  • Their mattress feels too soft or saggy on the current platform setup.

Whatever your reason, the goal is the same: increase height without damaging the mattress or the bed frame.

What Are the Safest Ways To Raise a Mattress on a Platform Bed?

1. Use a Bunkie Board or Support Board

A bunkie board is a low-profile, solid or slatted board that sits between your mattress and the platform.

  • Typically adds 1–3 inches of height.
  • Helps create a flatter, firmer surface.
  • Works well if your platform has widely spaced slats and you want more uniform support.

This is a common solution if your mattress feels like it’s sinking between slats.

2. Add a Mattress Topper

A mattress topper is an extra comfort layer that sits directly on top of your mattress.

  • Usually adds 1–4 inches of height.
  • Can make the surface softer or slightly firmer, depending on the material.
  • Easy to remove or adjust if you change your mind.

A topper is helpful if you want both extra height and a different feel, without altering the bed frame.

3. Use Bed Risers Under the Platform Legs

If your platform bed has legs, bed risers can be placed underneath them to lift the entire frame.

  • Commonly raise the bed by 2–8 inches.
  • Can provide more under-bed storage.
  • Keep in mind: this raises both the mattress and the frame.

Check that:

  • The risers are rated for the weight of the bed plus sleepers.
  • The legs of your platform fit securely into the risers so the bed doesn’t wobble.

4. Add an Extra Base or Low-Profile Foundation

Some people place a thin, low-profile foundation or sturdy board on top of the platform (if the platform design allows for it).

  • Adds extra height and stability.
  • Works best with flat, solid platforms, not delicate slats.
  • Make sure it doesn’t interfere with bed rails or cause the mattress to sit too high and slide.

Are DIY Solutions (Like Plywood) Okay?

Many people wonder if they can just slide a sheet of plywood between the mattress and the platform to raise the surface slightly and add support.

This can work when:

  • The plywood is smooth, with no sharp edges or splinters.
  • The thickness is appropriate (often around ½ inch to ¾ inch).
  • The platform is sturdy enough to handle the added weight.

Always check your mattress documentation for any guidance on acceptable foundations, since some manufacturers prefer certain types of support.

How Much Height Should You Add?

When deciding how to raise mattress on platform bed, it helps to think about:

  • Ease of getting in and out: Many people prefer a height where their knees are roughly at a right angle when sitting on the edge.
  • Bed stability: The taller the setup, the more important secure legs and a level floor become.
  • Mattress security: Very tall stacks (platform + board + thick mattress + tall topper) can make the mattress feel less stable, especially if there are no side rails.

Small changes—1 to 4 inches—are often enough to make a noticeable difference without affecting stability.

Common Concerns When Raising a Mattress on a Platform Bed

Will raising the mattress affect support?

Yes, it can. Adding boards or foundations can change how the mattress feels, often making it firmer and less flexible. Toppers, on the other hand, can make the bed softer while adding height.

Can raising the bed damage the mattress?

Potential issues include:

  • Uneven surfaces that cause dips or pressure points.
  • Gaps between slats that are too wide without additional support.
  • Hard or rough materials (like un-sanded wood) that can snag mattress fabric.

Choosing smooth, even, and well-fitted support surfaces helps protect the mattress over time.

Is it safe to use risers?

Risers are commonly used, but safety depends on:

  • The quality of the risers.
  • How well the platform legs fit and sit in them.
  • The weight being supported.

After installing risers, it’s useful to gently push and sit on different sides of the bed to check for wobbling.

✔️ Quick Mattress Takeaways

Key points to understand about how to raise mattress on platform bed:

  • Decide your goal first:
    • More height, more support, or a different feel?
  • Good options to raise height:
    • Bunkie board or support board (firmer, +1–3 inches).
    • Mattress topper (softer or firmer feel, +1–4 inches).
    • Bed risers under legs (+2–8 inches, more storage).
  • Check for safety and stability:
    • Platform and risers must handle the combined weight.
    • Surfaces should be flat, smooth, and even.
  • Avoid over-stacking:
    • Too many layers can make the bed feel unstable.
  • Review manufacturer guidance:
    • Some mattresses have preferred support types, especially for long-term use.
