What changes in the shop with an AI agent?
What changes is who answers first: the message no longer waits for you and is answered right away. These are four everyday shop situations before and after the CertuAI agent.
TodayA salesperson spends half an hour explaining firmness to someone who will still shop around at three stores
With CertuAIThe agent explains first, and the salesperson gets people who are ready to lie down and test
TodayA customer buys the standard double and finds out the bed needs a custom size
With CertuAIThe bed size comes up in the conversation before the purchase, with the lead time for made-to-measure
TodayDelivery and old mattress pickup agreed by word of mouth turn into an argument on the day
With CertuAILead time, cost, stairs and old mattress pickup recorded in writing in the conversation
TodayA question about back pain gets a different promise from each salesperson
With CertuAIThe agent explains firmness and composition and keeps health recommendations out of the conversation
What does a conversation handled by the AI look like?
Example conversation
The shop's AI agent
Customer: What's the difference between pocketed springs and foam?
AI agent: I'll explain using the store's own text: what you added.
Customer: Is this one firm or soft? Is it good for someone who sleeps on their side?
AI agent: I can give you the firmness of each line, but I don't recommend a mattress for pain or back problems. Want to come lie down in the showroom? I have your open slots.
Is an AI agent or manual customer service better for mattress stores?
The agent wins on repeated tasks, and the person keeps winning on anything that takes judgment. With manual service, someone at the shop has to stop what they are doing; with the CertuAI agent, the reply goes out on its own and you step into the conversation whenever you want.
| Aspect | The manual way | With the CertuAI agent |
|---|---|---|
| Questions about firmness and composition | Ties up a salesperson for half an hour, with no guarantee of a sale | The agent explains the lines you sell using the text you wrote |
| Non-standard size | The customer finds out in the store that their bed needs a custom size | The agent asks for the bed size first and gives the lead time for made-to-measure |
| Delivery and old mattress pickup | Agreed from memory and turns into a misunderstanding on delivery day | Lead time, cost, stairs and old mattress pickup recorded in writing |
| Visit to lie down and test | The customer shows up when the salesperson is busy with someone else | Visit booked in the conversation, with the line they want to test noted |
| Questions about pain and the spine | Each salesperson answers differently, some promising too much | The agent explains firmness and composition and does not get into health recommendations |
What does the WhatsApp agent do for mattress stores?
It does the customer service that is yours today. You teach the business once in the Brain, CertuAI's knowledge base, and the agent answers clients your way, with your rules.
Explanation of firmness and composition
Pocketed springs, foam, density and sizes, using the text you wrote in the Brain.
Bed size and custom sizes
The agent asks for the bed size before talking about mattress size, and gives the lead time for made-to-measure orders.
Delivery, stairs and old mattress pickup
Lead time, cost, whether the crew carries it up the stairs and whether it takes the old mattress, all in writing.
Booking a visit to try an instrument
Day and time to lie down in the showroom, with the line of interest already noted.
Limit on health recommendations
The agent explains the options and does not recommend a mattress for pain, back problems or treatment.
What questions do clients send on WhatsApp?
They are always the same, and the agent answers each one on its own. These everyday shop messages no longer depend on you having your phone in hand.
How does the agent start answering at the shop?
In three steps, on the same day. No installation, no code and no changing the number clients already know.
Teach your business
In one conversation, you explain catalog, prices, delivery, warranty, and rules, the way you would to a new employee.
The agent answers
It answers right away, logs every request and quote in the included CRM and follows up with people who went quiet.
How much does an AI agent on WhatsApp cost for mattress stores?
The Start plan costs US$ 75 per month and already includes the WhatsApp agent, your business Brain, the CRM, automatic follow-up and AI assistants, which come with every paid plan. Pro costs US$ 120 per month and adds the landing page, the wallet and 10 people on the team instead of 5. No contract and no setup fee.

Create my agentWhat needs to be ready before turning the agent on in the store?
The agent answers what is written, and nothing beyond that. Have these points defined before you connect WhatsApp.
- The lines the store sells, with firmness, spring or foam type and price range by size
- The text that explains firmness the way your store explains it in the showroom
- The standard sizes the store works with and how made-to-measure orders work, with lead time
- The delivery rule: lead time, cost, whether the crew carries it up the stairs and whether it takes the old mattress
- The warranty for each line, with its length and what it covers
- What the agent does not answer: any recommendation tied to pain, the spine or treatment
Whether the agent can suggest a line based on the weight and sleeping position the customer describes, or only explains the options.
The most common mistake: Letting the agent recommend a mattress for back pain. Explaining firmness and composition is customer service, but recommending a mattress for a spine problem is a different conversation, and an agent is not the place for it. Read how to fix this.
Frequently asked questions from mattress stores
Does the agent say which mattress is best for back pain?
No. It explains the differences in firmness and composition that you taught it. A recommendation tied to pain or the spine stays with you and with the professional the customer consults.
Does it answer about custom sizes and made-to-measure beds?
Yes, if you add which sizes the store can make and the lead time for each. It asks for the bed size before talking about mattress size.
Does it know whether a line is available in the store?
No. CertuAI does not read inventory. It answers about the lines, sizes and price ranges you added, and calls your team when the question is about a specific piece in the showroom.
Does it work for high-ticket sales that take days?
That is where it helps most: it answers the technical question, books the visit and keeps the prospect open in the CRM until the decision, which almost never comes on the first contact.
In what other fields does the CertuAI agent work?
In any business that serves customers on WhatsApp, because the Brain is written by you. These fields have a day-to-day closest to yours.
Where can I read more about CertuAI's WhatsApp agent?
These pages explain the same agent from another angle: how it works, price, common questions and comparisons between platforms.
In short
Explains firmness, size, warranty and delivery, books the visit to try the mattress in the showroom, and keeps the prospect open in the store's CRM until the decision comes.
