The Truth About ‘100-Night Trials’ in the UK: 5 Things Nobody Tells You

The Truth About ‘100-Night Trials’ in the UK: 5 Things Nobody Tells You

Buying a mattress online already takes a leap of faith. With brands promising risk-free 100-night trials, it all sounds easy. But is it really?

If you're shopping for a mattress in the UK, read this before you click "Buy Now".
Here's what most mattress companies don’t tell you about their return policies — and how to avoid costly mistakes.

1. You Might Have to Keep the Packaging

Many UK mattress trial policies require you to return the mattress in its original packaging. Sounds simple — until you realise:

  • You’ve already thrown away the vacuum-sealed plastic wrap

  • The original box was torn during unboxing

  • You didn’t read the small print

What to do:
Before unboxing your mattress, read the return policy carefully. If original packaging is required, keep everything, even the plastic wrap or zip bag.

2. “Free Returns” Might Not Be Free at All

Some mattress brands advertise “free returns” but hide the actual costs with vague wording like:

  • “Return shipping charges may apply”

  • “We’ll arrange collection at your expense”

  • “Handling fees will be deducted from your refund”

In reality, returning a mattress in the UK can cost £30–£70, depending on the size and courier.

Pro Tip:
Ask customer support directly:

“If I return the mattress, how much exactly do I have to pay?”
And always save their response.

3. 100 Nights = At Least 30 Nights (In Most Cases)

Many mattress trial policies include a minimum trial period — often 30 nights — before you’re allowed to return the product.

Why? Because your body needs time to adjust, especially with memory foam mattresses or orthopaedic models.

What you should know:

  • You can’t return the mattress during the first 2–4 weeks

  • Some brands may require up to 60 days

  • If you request an exchange, your trial might end there — or reset only partially

4. Exchanges Are Not Always Risk-Free

A few brands allow exchanges during the trial, but here’s what they often don’t tell you:

  • The replacement mattress may not come with a new trial period

  • You may only get one exchange per purchase

  • You may not be able to return the second mattress at all

Always confirm:

  • Does the new mattress have a fresh 100-night trial?

  • What happens if I also dislike the replacement?

5. Is It Really Uncomfortable — or Just New?

It’s normal to feel discomfort in the first few nights on a new mattress, especially if you’re switching from springs to memory foam.

Before giving up and returning it:

  • Sleep on it for at least 14 to 21 consecutive nights

  • Use a breathable mattress protector to reduce heat build-up

  • Rotate the mattress (if allowed) to adjust pressure distribution

Final Advice: Choose a Brand with Transparent Terms

Look for mattress brands that:

  • Clearly state their trial and return policy

  • Offer free home collection without requiring original packaging

  • Have real customer reviews about return experiences, not just comfort

At ZuroSleep, we believe transparency should start before your first night’s sleep.
