What a 100-night trial really costs you (and what to look for instead)

The 100-night trial changed the mattress market. It removed the fear of buying a bed you could not lie on first, and it made boxed mattresses possible. It also has a cost, and the cost is in every price you see. Here is how it works, what it is worth, and what to look for instead.

How a trial is funded

A brand that offers free returns for 100 nights will get a proportion of mattresses back, typically somewhere between five and fifteen per cent, more for softer or more unusual models. Each return means a collection, a lost mattress (it cannot be resold; it goes to charity or recycling), and often a second delivery of a replacement. That cost, spread across every sale, is added to the price. A rough rule: a trial with a 10 per cent return rate adds around a tenth to the price of every mattress, plus the logistics.

So a "free" trial is a return insurance policy that every customer pays for, whether or not they claim.

What happens to returned mattresses

Charity, if the charity will take them (many will not take used mattresses), otherwise recycling: the steel and foam are separated. Some brands have been caught reselling returns as new; the reputable ones do not. Ask what happens to yours.

What a trial tells you, and what it does not

A trial tells you whether you like this mattress after a few weeks. That is genuinely useful. It does not tell you whether the mattress will last, whether the foam is dense enough to still be level in year five, or whether the spring unit is well made. Those are spec questions, and a trial can lull you into skipping them. Many trial mattresses are built to be fine for 100 nights.

It also does not solve the main mattress problem, which is not "do I like it" but "which one should I buy". Choosing from thirty rolled mattresses with the same words on the box, then relying on the trial to sort it out, is the expensive way to shop.

The fine print

• A protector is often required; without it the return can be refused or charged.
• Some sizes and models are excluded.
• A minimum period (often 30 nights) before you can return, which is sensible.
• One return per customer in most cases.
• Collection fees creep in: "free returns" sometimes means free after a £50 to £100 collection.
• The trial replaces nothing: your legal 14-day right and your faulty-goods rights exist regardless. See your return rights.

The alternative: a swap instead of a refund

A mattress that is wrong is usually wrong in one direction: too firm, or occasionally too soft. That does not need a refund; it needs a topper or a different tension. A maker who offers a comfort swap, a topper first and then an exchange within the range, solves the actual problem at a fraction of the cost of a return, and can price the mattress without the return insurance built in. It asks something of the customer too: choose with more care up front, using the spec and a selector, rather than ordering three and sending two back.

That is the trade. A trial is easier if you do not want to think; a swap is cheaper if you are willing to.

What to look for

• A spec sheet with densities and gauges, so you are choosing with information rather than relying on the return.
• A tension choice, so "too firm" can be avoided at order.
• A swap policy with a topper first, and the costs stated.
• The 14-day right stated plainly, with the collection fee shown.
• What happens to returns: donated or recycled, never resold.

How we do it

Chapter has no 100-night trial, on purpose: it is one reason the prices are what they are. Instead: the full spec on every page, a four-question selector, Medium or Firm tension at no charge, a 30-night swap that sends a Soft Top topper first and then one exchange within the range in one visit, and the legal 14-day right with the collection fee on the page before you pay. Returned mattresses go to recycling. It is on the delivery and returns page.

The short version

• A free trial is paid for in every price, through the returns it funds.
• It tells you if you like it, not if it will last.
• Read the protector, exclusion and collection-fee terms.
• A swap with a topper first fixes the real problem for less.
• Your 14-day and faulty-goods rights exist with or without a trial.
