The 3 best Boxing Day mattress sales to help upgrade your sleep in 2023

Boxing Day mattress sales are now live – with several offers on par with what we saw during Black Friday weekend. If you endeavour to improve your sleep in the new year, now is a great time to capitalise on deals from the UK's best mattress brands. 

This is doubly true if you're hoping to refresh your overall sleep set-up – think pillows, linens and bed frames. You'll find plenty of mattress bundle deals ongoing, as well. For instance, Nectar is knocking 50% off mattresses and including a free duvet with purchase. Or you can buy a Nectar mattress bundle that comes with sheets, pillows and a bed frame and save up to £1,322

Head below for the three best Boxing Day mattress sales we suggest you check out before it's too late, including the aforementioned Nectar offer. If our recommendations don't tick any of your boxes, we've rounded up a selection of other great year-end sleep sales for you to browse. Let's get shopping...

Boxing Day mattress sales: quick tips

To make the most of this year's Boxing Day mattress sales, heed these helpful tips whilst browsing to ensure you're getting exactly what you need...

1. Know what you want ahead of time: Because saving money on a mattress doesn't mean much if it's the wrong fit for your body type and sleep style. Also consider if you frequently struggle with body aches, sleep warm or share a bed with a restless partner.
2. Glean user reviews: This will give you an idea of how a mattress will perform over an extended period of time, especially if a reviewer shares your preferences.
3. Research the price history: Doing this will give you a better sense of whether or not you're getting a deal. Fortunately, our dedicated mattress sales page provides information on past discounts to ease that burden on you.
4. Don't overlook bundle deals: In some instances, you'll be able to save even more on a mattress if you purchase it with extras – ranging from duvets and pillows to divans.
5. Make sure it comes with a trial period: When buying a mattress online sight unseen, you'll want a chance to try it out before committing to it. Plus, it takes roughly three weeks for your body to adjust to the feel of a new bed.
