Buying a new mattress in the UK is a significant investment, often costing upwards of £2,000 for premium models. However, the real value of your purchase isn’t just in the initial comfort—it’s in the protection that follows. When comparing Dreams vs Bensons for Beds, most shoppers find themselves lost in the “fine print.”
Does a 10-year guarantee cover a sagging surface? What is the hidden cost of swapping a mattress that feels like a brick? In this expert guide, we strip away the marketing jargon to reveal which retailer truly has your back when things go wrong.
The Comfort Guarantee: 100 Nights vs 40 Nights
In the UK bedding market, the “Comfort Guarantee” is your safety net. While both retailers offer one, the terms and conditions (and hidden fees) vary wildly.
Dreams: The 100-Night Sleep Guarantee
Dreams offers a generous 100-night comfort guarantee. If you find your mattress too firm or too soft, you can exchange it.
- The Catch: You must purchase a Dreams Mattress Protector on the same receipt as your mattress to qualify. If you don’t, the guarantee is void.
- The Cost: Dreams typically charges a flat redelivery fee (around £49) to swap the mattress.
Bensons for Beds: The 40-Night SleepPRO™ Guarantee
Bensons offers a shorter 40-night sleep guarantee.
- The Catch: This is usually tied to their Bensons for Beds SleepPRO™ technology. They argue that because their in-store tech helps you choose the right firmness, you don’t need 100 nights.
- The Hidden Cost: Unlike Dreams’ flat fee, Bensons often charges an administration fee of 10% of the original purchase price plus a redelivery fee. On a £1,500 mattress, that’s a £150 penalty just for an exchange.
Expert Insight: If you are unsure about your firmness preference, Dreams is the safer bet due to the longer trial and lower exchange costs.

Manufacturer Warranty: The “Fine Print” Exposed
When your mattress fails due to a manufacturing defect, you rely on the warranty. This is where the Dreams vs Bensons for Beds debate gets technical.
How Deep is Too Deep?
The most common complaint is a “dip” in the middle. Most UK retailers, including these two, will not accept a claim unless the indentation exceeds a specific depth.
- Dreams mattress sag warranty limit: Generally, an indentation must be deeper than 3cm to 4cm (depending on the brand) to be considered a defect.
- Bensons for Beds warranty claim process: Bensons requires a formal “Assessor” visit. If the assessor finds your bed base (slats) is faulty or spaced more than 7.5cm apart, your claim will likely be rejected.

Is the Extra Cover Worth It?
Both retailers will try to sell you extended insurance at the checkout. You might wonder, “Is Dreams bed insurance worth it?”
- Dreams Bedcover Service Plan: Covers accidental damage (stains, rips) which a standard warranty does not. If you have children or pets, this is a high-value add-on.
- Bensons Bedshield: Similar to Dreams, but often includes a professional cleaning service if a stain occurs.
Why Your Claim Might Be Rejected (Expert Tips)
To win the Bensons for Beds warranty claim process, you must avoid these common pitfalls:
- The Slats Trap: If your base slats are too far apart, the mattress lacks support and will sag. Most warranties require slats to be less than 7.5cm apart.
- The Stain Rule: Any liquid stain—even if unrelated to the structural failure—can void your hygiene warranty. Always use a protector.
- The “Turning” Clause: Many Slumberland and Sealy models are “No-Turn,” but they still require “Rotation” (head-to-toe) every month. Fail to do this, and your warranty might be void.
Final Verdict: Dreams vs Bensons for Beds
After comparing the fine print, here is our expert recommendation:
- Choose Dreams if: You want a longer trial period (100-night guarantee) and lower, flat-rate fees for exchanging your mattress. Their policy is more transparent for the average consumer.
- Choose Bensons for Beds if: You prefer a wider variety of “guarantee” lengths across different brands (like Slumberland or iGel) and are confident in using their SleepPRO™ tech to get the firmness right the first time.
Final Thought: Regardless of the retailer, always keep your receipt and buy a mattress protector. Without those two things, even the best warranty is just a piece of paper.
