How To Set Up An Emma Mattress: Step‑By‑Step FAQ Guide

If you’ve just unpacked a new mattress and are wondering how to set up an Emma mattress correctly, you’re in the right place. This FAQ-style guide walks you through each stage, from unboxing to first night, and answers the most common questions people have about getting it ready for sleep.

What should I do before opening the box?

Before you start, it helps to prepare your space so the setup goes smoothly.

Check these basics first:

Clear the area around your bed so you have room to move and unroll the mattress.
Set up your bed base (frame, platform, or foundation) and make sure it’s stable.
Have scissors ready for the plastic wrapping (avoid using knives if possible).
Wash your bedding so everything is ready once the mattress is fully expanded.

A supportive, even surface helps any foam or hybrid mattress perform as intended. Avoid placing it directly on broken slats, sagging bases, or uneven surfaces.

How To Set Up An Emma Mattress: Unboxing and Unrolling

How do I safely remove the packaging?

Most compressed mattresses arrive rolled and vacuum‑sealed. To set up an Emma mattress safely:

Place the box in the bedroom where you’ll use the mattress.
Lay the box on its side and slide the rolled mattress out.
Position the roll on the bed base or floor where you want it to rest.
Carefully cut the outer plastic wrap with scissors, avoiding the fabric.
Unroll the mattress until it lies flat, still in its inner vacuum seal.
Cut the vacuum seal along the edges, and let air in so it can expand.

Avoid cutting too deeply into the plastic, as this can damage the cover or foam layers underneath.

How long does it take to expand, and when can I sleep on it?

Expansion time

Once you’ve opened the vacuum seal, the mattress will start to expand almost immediately. Typically:

It reaches a usable shape within minutes to a few hours.
It may take up to a couple of days to reach its full height and feel.

You can usually sleep on it the first night, even if it hasn’t reached its final firmness and thickness yet. The feel may continue to settle and even out over the next few days.

Which side of the mattress should face up?

Many foam and hybrid mattresses have a specific top side designed for sleeping. To confirm you’ve set up an Emma mattress correctly:

Look for the brand label or logo on the side; this often helps you orient the top.
The top surface is usually softer or has a more detailed knit or pattern.
The bottom may have a grippier or more textured fabric to help keep it in place.

If the mattress is flippable (less common with layered foam designs), the instructions on the tag or booklet usually explain which side is intended for regular use.

What kind of bed base should I use?

A proper base is an important part of learning how to set up an Emma mattress correctly.

Compatible surfaces

Most boxed mattresses work well with:

Platform beds with a solid, flat surface
Slatted frames, as long as the slats are not too far apart
Adjustable bases, if the mattress is designed to flex

To support the mattress:

Ensure slats are close enough to prevent sagging between them.
Check that the frame is squeak‑free and doesn’t wobble.
Keep the surface dry and well-ventilated to discourage moisture buildup.

Why is there a new-mattress smell, and is it normal?

A mild “new mattress smell” (sometimes called off‑gassing) is common when unwrapping foam products.

The smell often fades within a few hours to a few days.
To help it dissipate faster, open windows or let the mattress air out in a ventilated room.
Removing all plastic promptly and leaving the bed unmade for the first few hours can also help.

If you’re sensitive to smells, you might choose to let the mattress air out in an empty room before using it overnight.

How do I protect the mattress after setup?

Once you’ve finished setting up an Emma mattress and it has expanded:

Add a breathable mattress protector to help guard against spills and everyday wear.
Use fitted sheets that match the mattress depth so they don’t pull or bunch.
Rotate the mattress (if recommended in the care instructions) to help it wear more evenly over time.

Gentle care can help maintain the feel and appearance of the mattress for longer.

Common setup mistakes to avoid

Here are a few issues people sometimes run into when figuring out how to set up an Emma mattress:

Leaving it in the box too long after delivery, which can affect expansion.
Using a damaged or sagging base, which can change how the mattress feels.
Cutting too aggressively into the plastic and nicking the fabric.
Not giving it time to expand, then assuming the firmness is “wrong” immediately.

Being patient with expansion and double‑checking your foundation often resolves early concerns.
