Your first 30 nights with a new mattress
A new mattress often feels quite different from your old one, and that's normal. Here's what to expect in your first 30 nights, how to look after a new mattress, and when it's worth giving Roomes a ring.
If you've a question about yours along the way, the team in our bed department in Upminster will happily help.
Why does a new mattress feel so different?
Because your body's used to your old one, dips and all. A new mattress gives you a different level of support, and it's quite common for your body to need time to get used to it.
The fillings settle over the first few weeks or months too, and more noticeably in mattresses with more luxurious fillings. That's the mattress shaping itself to you, not a sign that anything's wrong.
How long does it take to get used to a new mattress?
Usually a few weeks. The National Bed Federation says your body takes a while to adjust to a new surface, and that it could take a few weeks.
So try not to judge it on the first night, or even the first week.

What should you do on the first night?
Let the mattress air, then put a mattress protector on before you sleep on it. The National Bed Federation suggests giving a new mattress a good airing before use, and its advice is to always use a protector.
A protector keeps the mattress clean from the very first night, which makes looking after it much easier.
How often should you turn a new mattress?
Once a week for the first three months, then once a month after that. At Roomes, our bed care advice is to turn it end to end one week and side to side the next.
Turning regularly in those first months helps the fillings settle evenly. Non-turn mattresses shouldn't be flipped, though, so follow the care instructions that came with yours.
Is it normal for a new mattress to dip?
A little, yes. Shallow, even impressions where you sleep are normal, especially on a mattress with natural fillings.
The National Bed Federation says impressions like these are a normal characteristic of quality mattresses working as intended. What isn't normal is a deep dip on one side or a spring you can feel, and there's more on telling settling from wear.
How do you clean a mattress?
Mostly by keeping it clean in the first place. Use a protector, strip the bed and air the mattress for a few hours at least once a month, and vacuum the top lightly to cut down on dust and dust mites.
If something does get spilt, deal with it straight away, as the National Bed Federation advises. Check the care label before you use anything on the mattress, because the right treatment depends on the fabric and fillings.
What should you avoid?
Roomes' bed care advice is to avoid sitting on the edge of the mattress, and never to fold or roll it. Folding or rolling can damage the spring unit and tear the material.
Avoid putting a new mattress on an old or worn base, too. The National Bed Federation says an old or worn base can shorten the life of a new mattress and may affect its guarantee.

When should you call us?
Ring us if something's physically wrong rather than just different: a spring you can feel, a seam coming apart or a deep dip on one side. Roomes' after sales team is on 01708 255320, Monday to Friday 10am to 4pm.
If it still doesn't feel right after a few weeks, check the base first. A sagging base can make a sound mattress feel worn.
The short version
A new mattress takes a few weeks to get used to, so try not to judge it in the first week. Let it air, put a protector on from the first night, and turn it weekly for three months and monthly after that, unless it's a non-turn mattress.
Air it once a month, vacuum it lightly and deal with spills straight away. Shallow, even impressions are normal, while a spring you can feel, a seam coming apart or a deep dip on one side is worth a call.
If yours hasn't arrived yet, here's what happens on delivery day.
