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.
