Best Mattress Deals This Month

Where To Find Deals

UK mattress prices vary more than you might expect between retailers. The same mattress from the same brand can differ by £100 or more depending on where you buy it, whether a sale is running, and what extras come bundled in.

The most reliable places to check:

• Direct from the manufacturer (Emma, Simba, Nectar, Eve). These brands run frequent promotions, typically 30% to 50% off their listed price. The "sale" is almost always running, so the discounted price is effectively the real price.
• High-street retailers (Dreams, Bensons, ScS). Larger showroom chains run rotating promotions and are often willing to negotiate, especially on ex-display models and package deals with a bed frame.
• Online-only retailers (Amazon, Wayfair, Mattress Online). Prices are often lower because there is no showroom cost to cover, but you lose the ability to test before buying.
• Our mattress listings page pulls live prices from over a dozen UK retailers so you can compare without checking each site individually.

How Mattress Sales Work

The mattress industry relies heavily on sales events. Most major brands use a "was/now" pricing model where the "was" price is a full retail figure that almost nobody actually pays.

This makes it difficult to tell whether a deal is genuinely good or just standard pricing dressed up as a promotion. A few things worth checking:

• Look at the price history. Sites like PriceSpy and CamelCamelCamel track historical prices on some mattresses. If the "sale" price is the same as it was three months ago, it is not really a sale.
• Compare across retailers. If the same mattress is on "sale" at every shop at the same time, the discount is likely the manufacturer's standard promotion rather than a genuine markdown.
• Read the small print on bundle deals. "Free pillows" or "free headboard" promotions sometimes inflate the mattress price to cover the cost of the extras.

When To Buy

Mattress prices in the UK follow a predictable seasonal pattern:

• January sales: one of the best times to buy. Retailers clear old stock to make room for new models. Discounts of 40% to 60% are common across both high-street and online shops.
• Bank holiday weekends: most brands run promotions over the May and August bank holidays. Discounts are typically smaller than January but still worth checking.
• Black Friday and Cyber Monday (late November): online mattress brands go particularly hard on discounts during this period. Simba, Emma, and Nectar typically offer their lowest prices of the year.
• Boxing Day to New Year: similar to January, with end-of-year clearance pricing from most major retailers.
• Mid-year (June to September): the quietest period for mattress promotions. Fewer sales, but individual retailers sometimes offer competitive prices to hit quarterly targets.

If you can wait for a sale event, you will almost always save money. If you need a mattress now, check our mattress listings page for current offers across UK shops.

What To Watch Out For

• Trial periods are useful but read the terms. Most bed-in-a-box brands offer 100 to 200 night trials. If you return the mattress, the company collects it at no cost. However, some brands require you to keep it for at least 30 nights before returning, and a few charge a collection fee of £30 to £50.
• Delivery timescales vary widely. Rolled mattresses from online brands usually arrive within three to five working days. Traditional mattresses from high-street retailers can take two to six weeks, especially during sale periods when demand spikes.
• "Free" extras are not always good quality. A mattress topper or pillow set bundled with a deal is often a basic product that costs the retailer very little. Judge the deal on the mattress price alone.
• Firmness still matters more than price. No amount of discounting makes the wrong firmness right. If you are unsure what suits you, read our guide on choosing mattress firmness before committing.

Retailers Worth Checking

These are the major UK retailers we track prices from. Each has different strengths:

• Dreams: the largest specialist retailer with a wide range of brands and showroom testing
• Bensons for Beds: good mid-range selection with regular bundle deals on beds and mattresses
• Emma: own-brand bed-in-a-box with frequent heavy discounts and a long trial period
• Simba: hybrid mattresses popular in the UK with competitive sale pricing
• Nectar: budget-friendly memory foam with a 365-night trial period
• Silentnight: a long-established UK brand available through multiple retailers
• John Lewis: premium range with a price-match guarantee and reliable returns policy
• Amazon: competitive pricing and fast delivery, though no in-store testing and returns vary by seller
• Mattress Online: wide selection with lower prices thanks to reduced overhead
