Frequently Asked Questions

Common questions about mattresses & bedding.

Product Information

Are Sealy beds actually different from dealer to dealer?
Yes – In addition to our beds having different names & fabrics in different dealers, they are quite often built to a different architecture.
Will my mattress get a body signature (body impression)?

Body impressions in modern beds are normal and are generally an indication that the comfort layers are working with your body as they should. To determine if an impression is normal you would need to take a measurement. Place a long, straight edge, like a broom handle across the mattress surface. Measure from the underside of the straight edge to the top of the quilt design, not the stitching line. A measurement of 25.4mm or less would not indicate the presence of a manufacturing concern with your mattress.


If you are sleeping on a pillow top mattress, the comfort layers in the top of the mattress will conform to the shape of your body. The softer the comfort layers, the deeper you will sink into your mattress.

Utilising the entire surface of your mattress and rotating it as recommended in your Sealy Warranty will assist in providing even wear on your mattress, particularly during the first one to three month’s life of your mattress. The base that your mattress is on may contribute to more pronounced body impressions forming. To work out whether your base is the problem, one suggestion is to take the mattress off the base and try it on the floor. If the impressions are less evident this may indicate you have a problem with the base.

Will my mattress feel like the one I choose in the store when it is delivered?

There may be a “settling in” period of 6 to 8 weeks for a new mattress. Your new Sealy mattress will consist of new foams, silks, wools and cottons therefore these new materials require time to conform to your body shape and weight.

What if my mattress has an odour when it is delivered?

Any odour you detect when your mattress is first delivered is generally a short-term issue and should not last any longer than two weeks. However, if you are more sensitive to odours, it would assist by leaving your windows where the mattress is placed, opened, to enhance ventilation. Alternatively, you could also spray the mattress with a fabric deodoriser.

What if there is a noise with my mattress?

Noise may come from the mattress or the base. The best way to determine the source of the noise is to isolate the mattress from the base onto the floor and then attempt to replicate the noise.

Base Issue: There are a number of possible causes of noise with the bases, including castors/glides not being fitted correctly, headboard brackets, or the base rubbing against a nearby power point.

Mattress Issue: Misuse of the mattress such as sitting, standing or jumping can generate noise. If the noise occurs whilst sleeping, we would suggest contacting our Customer Care Department to discuss the issue further.

Every mattress is designed based on standards set by the Orthopaedic Advisory Board (OAB) to ensure optimal spinal alignment and sleep quality.

We recommend using our Mattress Selector Tool to find your perfect mattress based on your sleeping preferences and needs.

Do Sealy mattresses require a specific bed frame?

Are Sealy mattresses heavy and difficult to lift for cleaning?

Not at all! Sealy mattresses are designed for easy handling. Our Titanium Coil technology makes the mattress light and incredibly durable. Additionally, our mattresses come with side handles, making it easy to lift and rotate when needed.

Do I need to rotate my mattress?

Yes! To keep your mattress in great shape, we recommend rotating it every 3–6 months. This helps prevent uneven wear and ensures lasting comfort. Browse our Mattress Care Guide for more tips!

Noise may come from the mattress or the base. The best way to determine the source of the noise is to isolate the mattress from the base onto the floor and then attempt to replicate the noise.
Sometimes, you may hear a noise coming from your mattress or bed base. To find out where it’s coming from, try placing the mattress directly on the floor and gently move on it to see if the sound is still there.
  • If the noise stops: The issue might be with the base—such as loose castors (wheels), headboard brackets, or the base rubbing against a wall or power socket.
  • If the noise continues: It could be the mattress. This may happen if it’s been used for sitting, jumping, or putting heavy pressure on one spot.
If the sound happens while you’re sleeping and it’s affecting your rest, please reach out to our Customer Care Team. We’ll arrange a visit to investigate the issue.

What is the warranty period for Sealy mattresses?
