One mattress, one code, and next-day delivery free to most UK addresses. The Ergoflex 5G is a 23cm memory foam bed with a 30-night home trial, a free collection if it goes back, a ten-year guarantee once you register it, and interest-free finance if you would rather spread the cost. Put the best code above straight on your size, because the discount is not always the same from one size to the next.
These codes come from retailers we work with. If you use one and buy, the retailer pays us a commission. It does not change the price you pay. Codes come from the retailers’ affiliate networks and our sync checks them regularly; the date on each card is when that code was last checked. How we make money

How to use an Ergoflex code
Take the best Ergoflex code for your size
Read what is listed here, or spin the wheel to land on a random deal. The same code is not always worth the same on a single as on a super king.
Choose a size on ergoflex.co.uk
There is one mattress and six sizes, so this is the only decision to make. Get Code lifts the code while you do it.
Add it in the offer code box
Ergoflex puts that box on the basket page. Paste yours, click Add code, and the total drops before you reach Checkout Securely.
Is there an Ergoflex sale on right now?
Yes. We list 1 Ergoflex offer you can use today, with savings of up to 55% off, last checked today. Codes that stop working are moved to the expired list.
Ways to save at Ergoflex
- Register the guarantee within thirty days. The ten years only stands if you register the mattress with Ergoflex inside a month of delivery, and what it covers is indentation of more than an inch in the memory foam. Do it the week it arrives, while you still remember.
- Give it 21 nights before you decide. The home trial runs 30 days and Ergoflex asks for 21 nights of use before it will take one back. Memory foam needs about that long to stop feeling like somebody else's bed.
- One return per household, and not every postcode. The free-return trial is limited to one per household and leaves out Northern Ireland, northern Scotland, the Isle of Man, the Isle of Wight and the Channel Islands. Order the right size first time, too: a wrong size that has been unboxed is not covered.
- Check the weight guidance against your build. Ergoflex gives the 5G as suitable up to 18 stone per person, or 30 stone for a couple. Above that you want springs and a heavier gauge rather than foam, whatever the discount says.
- If you sleep hot, think about it twice. Memory foam kills movement and is lovely on pressure points, which is why couples get on with it, but it holds heat whatever the layer above is called. The 5G puts an airflow layer in the middle and a TENCEL cover on top, and it is still memory foam.
About Ergoflex
Ergoflex is a specialist memory foam mattress brand that has been operating in the UK since 2006. Their 5G Memory Foam mattress uses temperature-sensitive visco-elastic foam to deliver deep pressure relief and contouring support.

Delivery, returns and codes at Ergoflex
Delivery
Next-day delivery from Ergoflex
Order an in-stock size before 10am, Monday to Thursday, and it ships free, next day, to most UK mainland addresses. There is a delivery calendar in the checkout if you would rather name a date, and a postcode checker for the places the free service does not reach.
- Saturday delivery costs extra and is not offered on super kings
- The carrier's insurance stops at your front door, or the building's front door in a block of flats
- Next day misses the Highlands and islands, Ireland, the Isles of Scilly, the Isle of Wight and the Channel Islands
- The foam takes up to four hours to come back to shape and can be slept on the same day
Returns
Sending an Ergoflex back
Tell Ergoflex inside the thirty days and it arranges a pick-up and a refund, and the mattress need not go back in its box.
- The free-return trial is for households, not business or bedding-trade buyers
- Pillow, protector and TENCEL cover: two years of cover each
- The ten-year guarantee covers an indentation of more than an inch in the memory foam
Using codes
What an Ergoflex code is worth
Ergoflex calls it the offer code box and it sits on the basket page, so the saving appears before you click through to pay. Codes can be worth different amounts on different sizes, so check what yours gives on the size you want.
- Percentage off the 5G
- Free pillow or protector with an order
- Seasonal codes around the sales
Is the Ergoflex code a good deal?
Yes, and a simple one, because there is nothing else to choose. One mattress, one feel, six sizes, sold direct only, so the code is the whole negotiation. What that buys is a proper slab of memory foam with an airflow layer underneath and a washable cover, from a brand that has been selling the same bed since 2006 and has never pretended to sell you anything else. It is a couple's mattress and a side sleeper's mattress more than a hot sleeper's. Our view: take the code, get the size right first time, and register the guarantee the week it lands.
The only mattress Ergoflex sells
- Ergoflex 5G Mattress: 23cm in total, with 9cm of high-density memory foam over a 5cm airflow layer and a 9cm base, inside a removable and washable TENCEL cover. One feel and one-sided, so you rotate it rather than turn it. Best suited to couples and side sleepers who want foam to take the pressure, and rated by Ergoflex up to 18 stone a person.

Ergoflex discount code questions
On ergoflex.co.uk, add your size to the basket, where the offer code box sits. Add it there and the total changes before you click through to pay. Ergoflex's own 'save up to' banners compare the 5G with a TEMPUR price rather than a previous Ergoflex price, so judge the deal on what your size costs with the code applied.
Thirty days, with a collection Ergoflex pays for and your money back, and 21 nights of use before you decide. It is one return per household, it does not cover a wrong-size order that has been unboxed, and a few outlying areas are excluded.
Yes, the Ergoflex 5G, in six sizes, direct from Ergoflex rather than through the bed shops. There is no cheaper model to trade down to, which is why the code and the size you choose are the only variables.
Nothing standing. If one of those is running it will appear with the other offers above, dated, so weigh it against the codes already there.
Yes. Interest-free terms are offered at the point of payment, which takes the sting out of a king or super king.
Yes to both. An in-stock size ordered early in the week reaches most UK addresses the next day for nothing. Saturday costs extra and is not offered on super kings.
