Frequently Asked Questions
Q. When do Cyber Monday mattress sales end in the UK?
A.Cyber Monday sales typically run through the end of the week, often called "Cyber Week," ending around December 3rd-5th. However, the best bundles and stock on popular sizes can sell out fast. We recommend buying as early as possible.
Q. Are Cyber Monday deals better than Boxing Day sales?
A. The deals are almost always identical. There is no benefit to waiting for the Boxing Day sales. Brands like Nectar and Emma now run their "Black Friday" event right through Cyber Monday and into December. Shopping early is a major advantage as it guarantees you get the deal and avoid the pre-Christmas delivery cut-off.
Q. Are these Cyber Monday deals "real"?
A. Yes, but you must be careful. Some retailers inflate the "RRP" (Recommended Retail Price) to make a discount look bigger. The deals we list here are verified. We focus on the final price and the value (like free bundles) to ensure you're getting a real deal.
Q. How do these deals compare to Simba's Cyber Monday sale?
A.Simba is a top UK brand and typically offers around 45% off for Cyber Monday. The deals from Nectar (up to 60%) and DreamCloud (up to 57%) are often more aggressive in terms of pure percentage discount. Simba is a fantastic hybrid, but Nectar and DreamCloud are currently offering deeper discounts.
Q. Can you return a mattress bought on Cyber Monday?
A. Yes, and this is crucial. All the bed-in-a-box brands on our list (DreamCloud, Nectar, Origin, Emma) offer their full, standard risk-free trial (from 200 to 365 nights). This is a huge advantage over traditional retailers like Mattress Online, whose trial periods may be shorter and have stricter conditions.
Q. How much should I pay for a good mattress on Cyber Monday?
A. These sales make premium mattresses much more affordable. For a King size, you can find an excellent budget-friendly foam or hybrid mattress for under £500 (like the Nectar). A premium, luxury hybrid (like the DreamCloud or Origin) will be in the £500 - £700 range, often with free accessories included.
