Most people pick a mattress store by whichever one shows up first. But the store decides which brands you can try, whether anyone helps you narrow it down, and how fast the bed shows up.

What Matters Most When Choosing a Mattress Store
How many brands you can try
The store decides your options. A store that carries mostly one manufacturer, or mostly its own label, limits what you can compare before you buy.
Whether anyone helps you narrow it down
A big showroom only helps if you can find the right bed in it. BedMATCH sleep technology measures your body and turns a floor of options into a short list in a few minutes.
How fast it arrives
If your current mattress is the problem, waiting a week for delivery is a week of bad sleep.
What happens if you choose wrong
Trial length gets the headlines, but minimum nights, fees, and whether you can return or only exchange matter more. Ask before you buy.
Compare 20+ Brands in One Visit
BedMATCH measures how your body actually distributes weight, then narrows the floor to what fits.
Best Mattress Store for Trying Online Brands in Person
Helix and Avocado are sold mostly online, which normally means buying without lying down first. Sit 'n Sleep carries both, along with Purple, Casper, and Nectar, so you can try them side by side with Tempur-Pedic and Beautyrest. See our comparison of online mattress brands.
Best Mattress Store for Next-Day Delivery in Southern California
Order from Sit 'n Sleep by 4 PM for next-day local delivery across Los Angeles, Orange County, the Inland Empire, and Ventura County. See our delivery details.
Sit 'n Sleep, Mattress Firm, and Ortho Mattress Compared
How We Compared
We compared the three stores on five things that matter most to a Southern California shopper: brand selection, help choosing, delivery, price promises, and trial and return terms. For Mattress Firm and Ortho Mattress we used only their public policy pages, store listings, and company materials, checked in October 2026 and linked next to each claim. What can vary: brands and models on the floor at a given store, delivery days by zip code, and promotions. Our view comes from 45 years on the sales floor.
Sit 'n Sleep
Sit 'n Sleep has been family-owned for more than 45 years and operates only in Southern California, with 37+ stores across Los Angeles, Orange County, the Inland Empire, and Ventura County.
The biggest difference is choice. More than 20 brands are on the floor, from Tempur-Pedic, Beautyrest, and Sealy to online brands like Purple, Casper, Helix, and Avocado that most people only know from ads. Every store has BedMATCH sleep technology, which measures how your body presses into a mattress and matches you to the comfort levels that fit.
Order by 4 PM for next-day local delivery, with in-home setup and old mattress removal available, and if you find a lower advertised price on a comparable mattress, we will beat it. Our 120-night comfort trial lets you exchange if the mattress is not right, with terms that vary by brand.
- Ask in store Start with BedMATCH so it can match you to the right comfort level, then try your top three picks back to back for ten minutes each in the position you sleep in.
Mattress Firm
Mattress Firm is the largest mattress specialty chain in the country, with 2,100+ stores in 45 states. Since February 2025 it has been owned by Somnigroup International, the company formerly called Tempur Sealy, which also makes Tempur-Pedic, Sealy, and Stearns & Foster. Sources: Somnigroup press release, Feb. 5, 2025; Somnigroup investor presentation, Aug. 2026.
With that many locations, there is likely one near you, and if you move, you can still reach a store. It carries major brands, including Tempur-Pedic, Sealy, and Stearns & Foster from its parent company, plus its own Sleepy's line. It offers a 120-night sleep trial that allows returns as well as exchanges, with fees, and matches comparable advertised prices. [source]
Where Sit 'n Sleep stands apart is the mix on the floor and BedMATCH sleep technology in every store.
- Ask in store Ask which models on the floor are made by Mattress Firm's parent company, and what the exchange and return fees are under the sleep trial.
Ortho Mattress
Ortho Mattress was founded in 1957 and makes many of its own mattresses in Southern California. It lists 23 locations: 22 in Southern California, including San Diego County, and one appointment-only showroom in Phoenix. Sources: Ortho Mattress company history; Ortho Mattress store locations.
Its selection is mostly its own mattresses, plus Beautyrest, Aireloom, and Casper, so you will compare fewer national brands. It offers a 100-night comfort guarantee with one exchange after at least 30 nights, and delivers in Southern California four days a week. Sources: Ortho Mattress comfort guarantee; Ortho Mattress shipping and returns.
It makes the most sense if you specifically want a mattress built by a local manufacturer, or you live near one of its San Diego County showrooms.
- Ask in store Ask which models are Ortho-made, and get the comfort guarantee terms in writing, including the minimum nights and exchange delivery charge.
What to Ask Any Mattress Store Before You Buy
- Can I try this exact model here today? Some stores show a model on the floor that only ships from a warehouse.
- What are the trial terms, in writing? Minimum nights, fees, and how many exchanges.
- When can it be delivered? And what does delivery and old mattress removal cost?
- Who handles the warranty? The store or the manufacturer.
- Will you beat or match a lower advertised price? Get the terms.
Common Mistakes I See on the Sales Floor
Picking the store before the mattress
People go wherever is closest, then choose from whatever that store happens to carry. Start with which brands you want to try, then find the store that has them side by side.
Not asking about the trial until there is a problem
Every store's trial has fine print. The time to ask about minimum nights and fees is before you buy, not on night 40.
Testing for two minutes
Wherever you shop, lie on your top two or three picks for at least ten minutes each, in the position you actually sleep in.
Sales floor observations by Drew Miller, Vice President, Sit 'n Sleep
Why In-Store Testing Matters
A mattress is one of the few big purchases most people make without trying the real thing first. Wherever you shop, lie down on it.
That is not something a product page can solve. It is something you find out in about fifteen minutes lying down.
Every Sit 'n Sleep store offers BedMATCH, a diagnostic fitting that takes about three minutes. You lie down on a calibrated bed while it takes more than one thousand measurements of your body, then narrows the floor to the comfort range that actually fits you. It is free and you do not need an appointment.
