The longest mattress trial in the UK is Nectar's, at 365 nights. Simba, Emma, Eve and Dormeo give 200 nights, OTTY and Luxe Mattresses 100, and several of the best traditional makers give none at all. We checked every brand's terms on 3 November 2026. Here is the full table, what the small print takes away, and whether a longer trial should decide which mattress you buy.
Mattress trial periods by brand#
Trial lengths and guarantees as published by each brand on 3 November 2026. Brands change these, so confirm on the product page before you order.
| Brand | Sleep trial | Guarantee | Notes |
|---|---|---|---|
| Nectar | 365 nights | Forever warranty | A full year. The longest trial from a major UK brand. |
| Simba | 200 nights | 10 years | On every Hybrid in the range. |
| Emma | 200 nights | 10 years | Emma says "up to" 200 nights; every Original model we list gets the full 200. |
| Eve Sleep | 200 nights | 10 years | Doubled from 100 nights since our review. |
| Dormeo | 200 nights | Up to 20 years | Trial covers mattresses and toppers. Previously 60 nights. |
| OTTY | 100 nights | 10 years | OTTY says "up to" 100 nights. |
| Luxe Mattresses | 100 nights | 10 years | Hand-made in the UK; the only British maker we test with a proper home trial. |
| Silentnight | 60-night comfort exchange | 10 years (Sleep Now range) or lifetime when registered | An exchange for another Silentnight mattress, not a refund. |
| Luff Sleep | No trial | 10 years | 30-day returns through the retailer, excluding sale items. |
| Millbrook Beds | No trial | 5 years | Made to order; 30-day returns through the retailer, excluding sale items. |
| The Foam People | No trial | 5 years | Cut to order, so no returns if it does not suit. Prices start under £110. |
Hypnos and Vi-Spring, the traditional luxury makers, do not offer a home trial as standard; you try them in a showroom and the decision is final, although individual retailers sometimes add their own exchange scheme. Casper and Brook + Wilde offered 100 nights when we reviewed them.
Which mattress has the longest trial?#
Nectar, at 365 nights. You can sleep on a Nectar for a full year and still return it for a refund. That is a genuine advantage if you are an indecisive buyer or you are changing mattress type, say from springs to memory foam, and want to be sure. Read our Nectar review before you let the trial decide, though: the mattress itself is a plain memory foam build, and a long trial does not make a mattress better, it only makes the decision reversible.
Behind Nectar, four brands give 200 nights: Simba, Emma, Eve and Dormeo. Six to seven months is more than enough time to know, so in practice there is no difference between 200 and 365 nights for most people.
Is a 100-night trial standard?#
It was the standard when bed-in-a-box brands arrived in the UK, and it is still what OTTY, Luxe Mattresses and most smaller online brands offer. 100 nights is enough: brands ask you to keep the mattress for at least 30 nights before returning it because foam and springs settle and your body adjusts, and nearly everyone who returns a mattress does so within the first two months. The brands that moved to 200 or 365 nights did it for marketing as much as for you. What matters more than the number is what the trial excludes.
What the small print takes away#
- A minimum period. Most trials require you to keep the mattress for 14 to 30 nights before you can return it.
- Condition. The mattress must be undamaged and unstained. Use a protector from the first night.
- One trial per household. Brands generally allow one trial return per customer or address, so you cannot work through the range.
- Exchange, not refund. Silentnight's 60-night comfort guarantee swaps the mattress for another Silentnight; it does not give your money back.
- Collection. Most brands collect free in mainland Britain and charge for Northern Ireland, the Highlands and islands. Some ask you to arrange it.
- Sale items. Retailer returns policies, as opposed to brand trials, often exclude sale purchases. Luff and Millbrook mattresses bought in a sale fall into this.
Our guide to how mattress trials work covers the mechanics, and your statutory rights under the Consumer Rights Act 2015 apply on top of any trial if the mattress is faulty.
Should the trial decide which mattress you buy?#
No. Buy the mattress that suits how you sleep, then treat the trial as insurance. The brands with no trial, Millbrook, Luff and The Foam People, make some of the best-value mattresses we have tested; what you give up is the right to change your mind, so for those you should be sure of the firmness and type before ordering. A trial matters most when you are switching to a type you have never slept on, such as memory foam or latex, or buying for someone else.

Frequently asked questions#
Which mattress company has the longest trial period?#
Nectar, with a 365-night home trial. Simba, Emma, Eve and Dormeo offer 200 nights.
Is a 200-night trial better than 100?#
Only marginally. Most people know within six weeks whether a mattress suits them, and brands make you keep it for at least 30 nights anyway. A 100-night trial with free collection is better than a 200-night trial that charges you to return it.
Can you really return a mattress after sleeping on it?#
Yes, that is the point of a trial. The mattress must be clean and undamaged. Returned mattresses are usually donated to charity or recycled rather than resold.
Do you get a full refund on a mattress trial?#
From the online brands in the table, yes, provided you meet the conditions. Silentnight's scheme is an exchange, and retailers' own returns policies may deduct a collection fee.
Which mattresses have no trial?#
Mattresses made to order, including Millbrook, Luff and The Foam People, and traditional luxury makers such as Hypnos and Vi-Spring. For these, try the mattress in a showroom or be confident in the firmness before you buy.
