Firmness has no shared scale
One brand's medium-firm is another brand's plush, and a 1 to 10 rating only means something inside your own lineup. Shoppers want it translated against the bed they sleep on now.
Nobody can lie on a mattress through a screen, so the questions pile up at checkout: how firm, which model for two different sleepers, what the trial allows and who hauls the old one away. A Loop Voice agent answers them by phone once a shopper leaves checkout, working from your product pages, trial terms and delivery options. It describes the build and never promises to fix a bad back.
The short answer
For a mattress brand, an AI voice agent does the showroom's job by phone: it calls shoppers who left checkout and explains firmness, which model your guide suggests for a sleep position, the trial and return pickup, delivery and old-mattress removal. Loop Voice hasn't published a mattress customer story yet, so measure your own from day one: answer rate, attributed orders and trial returns, against a share of abandoned checkouts you don't call. The agent makes no back-pain claims, because the FTC expects scientific evidence behind health claims.

When two people share a bed, the buyer is choosing for both. The answer depends on your catalog: a split king on an adjustable base, a dual-firmness model, or the trial.
Trial length, minimum nights before a return, pickup or donation, and any return fee decide whether the trial feels safe, and the policy page that spells them out isn't next to the Add to cart button.
Boxed or white glove, the stairs, old-mattress removal and its fee, and in some states a recycling fee. A shopper meeting those choices for the first time at checkout can stall there.
A shopper who left a queen hybrid at checkout gets a call about firmness and the trial, then the checkout link by text, and the flow ends once the order lands. If your mattresses are already on sale, drop the discount from the second call and lead with the trial terms.

Hi Maria, it's Sam, an AI assistant calling from [Store]. If you'd rather not get these calls, just say stop. I saw the queen hybrid in your cart. Was there a question I can answer?
Shopper
My husband likes firm and I sleep on my side. Also, my back's been bad. Will this help?
AI agent
I can't promise any mattress will help back pain; if it's ongoing, that's one for your doctor. We rate this model 6 out of 10 for firmness, and our guide suggests it for side and back sleepers, so it sits between what you each like.
Shopper
And if we hate it?
AI agent
You'd have 100 nights to try it at home. Our policy asks for 30 nights first; after that, we pick it up and refund the price.
Shopper
Do you take the old one away?
AI agent
With white glove delivery, yes, as an option at checkout. Boxed delivery doesn't include it. Shall I text you the cart so you can compare both?
Shopper
Sure. I'll show him tonight.
What shoppers say
“Will this help my back?”
How the agent answers
It doesn't say yes. The agent describes the build and firmness, suggests a doctor for ongoing pain and won't repeat a review that says the bed fixed someone's back.
What shoppers say
“He likes it firm, I like it soft.”
How the agent answers
It lays out what your catalog offers, such as a split king on an adjustable base or a dual-firmness model, with the trial as the fallback.
What shoppers say
“Is there fiberglass in it?”
How the agent answers
It answers from your published materials list and law label. If your knowledge base is silent on it, the agent won't guess at materials; the question shows up on the answer gaps list so you can add the answer.
What shoppers say
“Will it work on my adjustable base?”
How the agent answers
It checks the base compatibility note on your product page, and the base's specs if you sell bases. If the page is silent, it doesn't guess.
What shoppers say
“Is it made in the USA?”
How the agent answers
Only in the exact words on your product page. If the page says "assembled in USA from imported materials", the agent says that, not "made in USA".
Under Settings, Integrations, link the store that takes your orders: Shopify, WooCommerce or Checkout Champ. A queen hybrid left at checkout then starts the flow with its model and size, and an order stops it.
Fill the knowledge base with your firmness scale, each model's layers and suggested sleep positions as your pages state them, sizes, base compatibility, trial terms, pickup steps, delivery options and removal fees, then check the readiness score.
Use the strict guardrail template, keep the built-in rule that escalates medical questions, and add a custom guardrail: never say a mattress relieves, prevents or treats pain.
Copy the abandoned checkout template. For the second call, choose between a code, capped at the maximum value you set, and the trial terms on their own.
Add a trial check-in flow and turn on the gather feedback objective, so a complaint comes back as a ticket with the call summary.
Read the calling rules guide before launch: a shopper has to agree in writing to marketing calls in an AI voice, and that consent comes from your checkout or forms, not from Loop Voice. Calls go out only inside your hours in each shopper's time zone, and anyone who opts out, by saying stop on a call or texting STOP, is skipped by every flow and campaign after that.
Run the simulator with the skeptical shopper persona and a couple you write, one who wants firm and one side sleeper with a sore back, and check that the back question never gets a promise.
It can explain your firmness scale and say which of your models your own guide suggests for a sleep position. It works from your product pages, not general sleep advice, and says plainly that the trial is how a shopper finds out for sure.
After any minimum nights in your policy, and early enough that a problem can be fixed before the return window closes. Set a frequency cap so a customer hears from you once during the trial.
The inbound agent reads your return terms back, checks the order and opens a ticket with the call summary so your team can arrange the pickup. Inside support hours it can put the caller through to your team instead.
Their questions are more technical: base compatibility, split king setups, wall clearance and power. Load each base's specs and the mattresses that work on it, and the agent answers from those.
Run a holdout: leave a share of abandoned checkouts uncalled with a split step and compare order rates. Loop Voice's September 2026 benchmark estimated a +5.7 point lift in 5-day orders for abandoned-checkout shoppers the flows reached, across five stores (95% interval 4.4 to 6.9 points); that's an estimate, not a randomized holdout, so your own test counts more. The holdout guide shows the setup.
