Replacing a mattress is one of those purchases most people make once a decade or so. The average lasts 7 to 10 years, so when the time comes it tends to feel like a notable outlay. Add new bedding, a mattress topper, or a bed frame into the same order and the total rises quickly.
The good news is that mattress retailers run some of the deeper sales in the home category. Timing your purchase well and checking for active voucher codes before you pay can take a meaningful chunk off the final price.
We’ve tracked mattress and bedding prices across UK retailers over time and found the gap between sale price and full price can reach 40% or more on the same product, most noticeably around January and Black Friday. Checking before you commit is always worth doing.

When Are Mattress Prices at Their Lowest?
We’ve seen the strongest mattress reductions land in three main periods: January clearance, bank holiday weekends, and Black Friday. January tends to bring the widest price drops, as retailers clear stock ahead of new ranges arriving in spring.
Many brands also reduce outgoing mattress models when updated versions launch, worth checking if you’re not set on the latest spec.
A 10% code on a £700 mattress saves £70. On a £1,200 mattress, that becomes £120. Even a smaller percentage off a higher spend adds up to a sum worth taking a minute to find.
Bedding and Linen Deals
A new mattress often prompts new bedding. Duvets, pillows, protectors, and sheet sets bought at the same time can push the total order price up considerably.
Our bedding discount codes page covers current offers on:
- Duvets and pillows
- Mattress toppers and protectors
- Sheet sets and fitted sheets
- Bed linen bundles
For a full bedroom refresh, furniture discount codes and home accessories deals are worth checking alongside.
Mattress Bundle Deals
Some retailers package mattresses with pillows, protectors, or bedding sets at a lower total than buying each item separately. Emma Sleep and Silentnight both run these during seasonal promotions.
Checking brand-specific pages before placing your order helps you spot active bundles, these aren’t always shown on the homepage and can disappear quickly once stock runs out.
Buying for a Child’s Room or Nursery?
Children’s mattresses and nursery bedding sit in a separate category with their own promotions. Our nursery and bedding discount codes page covers current deals.

What to Compare Before You Order
Mattress pricing varies widely across retailers for similar materials and support levels. Before placing an order, it is worth checking:
- Trial periods, many brands now offer 100 nights or more
- Warranty length, this varies from 2 years to over 10
- Delivery charges, free delivery thresholds differ by retailer
- Returns policy, some charge a collection fee, others do not
Once you’ve settled on the right mattress, apply the strongest available discount code before confirming payment.
Other Bedroom Savings Worth Checking
If you’re updating the wider room at the same time, additional codes are available across:
When seasonal promotions overlap, buying across categories in the same period can reduce the overall cost of a room refresh.
Common Questions
How Long Should a Mattress Last?
Most mattresses last between 7 and 10 years, depending on the material and how regularly they’re used. Visible dips, reduced support, or consistent discomfort when sleeping are signs it may be time to replace.
Do Mattress Prices Change Through the Year?
Yes. January, bank holidays, and Black Friday bring the most consistent reductions. New range launches in spring often trigger price drops on outgoing models too. Checking current offers before buying is always worth doing.
Are Online Mattress Trials Actually Free?
Many brands offer home trial periods of 100 nights or more. Always read the terms carefully, some charge a collection fee for returns, and conditions vary between retailers.
Can You Use More Than One Voucher Code?
Most retailers allow one promotional code per order. If you have more than one, test each separately to find which gives the largest reduction before completing the purchase.
