016 Questions to Ask Before You Buy a Mattress

Walking into a mattress store without a plan is how people end up buying the wrong mattress. The good news: a few well-placed questions will tell you almost everything you need to know — about the mattress, the store, and whether it's actually the right fit for you.

Here are the six questions worth asking, and what to listen for in the answers.

031. What Type of Mattress Would Work for My Sleep Style?

Not every mattress type suits every sleeper. Before testing anything, let the associate know your priorities:

  • Do you sleep hot or cold?
  • Do you have any chronic pain — back, hips, shoulders?
  • Do you share the bed? Does your partner move around a lot?
  • Do you prefer to feel "in" the mattress or "on top" of it?

A good associate will use those answers to steer you toward the right construction type:

  • Memory foam — Conforms closely, great for pressure relief, tends to retain heat unless it has cooling layers
  • Hybrid — Combines foam comfort layers with a pocketed coil base; good balance of support, pressure relief, and airflow
  • Latex — Responsive, naturally cooling, durable; good for people who want pressure relief without the "sinking" feel of foam
  • Innerspring — Firmer, more traditional feel, excellent airflow; less pressure relief than foam or latex

If the associate skips these questions and goes straight to showing you the most expensive option, that's a red flag.

042. What Firmness Level Should I Actually Try?

Firmness is one of the most misunderstood things about mattresses. Most brands have their own firmness scales that don't mean the same thing from brand to brand. "Medium-firm" from one manufacturer feels completely different from another's.

Ask the associate to point you toward specific mattresses based on your needs — not just the label. Then try them.

General guidance:

  • Side sleepers usually do better on softer to medium surfaces — they need pressure relief at the shoulder and hip
  • Back sleepers typically do best on medium to medium-firm — enough support for the lumbar without too much pushback
  • Stomach sleepers generally need firm support to keep the hips from sinking and the spine from arching
  • Combination sleepers often need medium — flexible enough for multiple positions

Body weight also affects firmness perception: a 150-lb person and a 220-lb person will experience the same mattress very differently.

053. Does This Mattress Work for My Sleep Position?

Be specific about how you actually sleep — not how you intend to sleep. If you start on your side and end up on your back, say so. If you have shoulder pain from side sleeping, mention it.

A knowledgeable associate should be able to explain:

  • Whether a given mattress provides appropriate pressure relief for your position
  • Whether the zoning (if present) aligns your spine correctly
  • Whether the mattress has enough give at pressure points (hips, shoulders) without letting the center sag

When you test the mattress in the store, lie in your actual sleep position for at least 5–10 minutes. Not on your back if you sleep on your side.

064. What Are the Key Features — and Which Ones Actually Matter?

Mattress marketing is full of proprietary terms and buzzwords. Ask your associate to explain what a feature actually does — not just what it's called.

Features worth asking about:

  • Cooling technology — Gel infusions, copper, phase-change materials, or open-cell foam all address heat retention differently. Ask how effective it actually is.
  • Motion isolation — Important if you share a bed with someone who moves. Pocketed coils and dense foam both perform well here.
  • Edge support — Matters if you sit on the edge of the bed frequently or share a bed and use the full surface.
  • Coil count vs. coil gauge — For innerspring and hybrid mattresses, coil gauge (thickness) often matters more than count.

If an associate can't explain what a feature does for you specifically, that's worth noting.

075. What's the Warranty, and What Does the Trial Period Look Like?

These are two different things and both matter.

The warranty covers manufacturing defects — sagging beyond a certain depth (usually 1" to 1.5"), structural failures, material breakdown. Ask what the threshold is, whether it's prorated, and what the process looks like if you need to make a claim.

The comfort trial is your window to decide if the mattress is actually right for you. A good trial period is at least 90 days — 120 is better. Ask:

  • Is there a required break-in period before you can return?
  • Is the exchange free, or are there fees?
  • Is it a return or an exchange?
  • Do you need to keep the original packaging?

At LA Mattress, we offer a 120-night comfort guarantee. If it's not right, we'll work with you to make it right.

086. What Else Do I Need to Make This Work?

A mattress doesn't exist in isolation. Ask about:

  • Foundation requirements — Some mattresses require a specific base type to keep the warranty valid. A memory foam mattress on a slatted frame with wide gaps, for example, can void the warranty and feel worse.
  • Adjustable bases — If you're interested in head or foot elevation, ask which mattresses are compatible. Not all foam mattresses flex well with an adjustable base.
  • Pillows — Pillow height affects spinal alignment just like mattress firmness. A good associate will mention this.
  • Mattress protectors — Often required to keep the warranty valid. Worth asking about before you leave.

09Tips for Getting the Most Out of Your Store Visit

  • Wear comfortable clothes you can actually lie down in
  • Bring your partner if you share a bed
  • Tell the associate your budget early — it saves time and prevents awkward pivots later
  • Lie on each mattress for at least 5 minutes in your actual sleep position
  • Don't let anyone rush you
  • Ask about current promotions — they change frequently

Our associates at any of our LA showrooms are here to help you find the right match — not to steer you toward the highest margin item. If you're not sure where to start, that's fine. Just tell us how you sleep and we'll go from there.

10FAQ

How long should I spend testing a mattress in a store?

At least 5–10 minutes per mattress, lying in your actual sleep position. It feels awkward, but it's the only way to get a real sense of how a mattress feels. Sitting on the edge or pressing it with your hand tells you almost nothing useful.

Should I tell the salesperson my budget?

Yes. It saves time for both of you. A good associate won't judge you for having a budget — they'll use it to show you the best options within your range rather than wasting time on things you can't or won't spend.

What's the difference between a trial period and a warranty?

A trial period is your window to decide if you like how the mattress sleeps. A warranty covers defects in manufacturing. Make sure you understand both before purchasing.

Do I need to buy a new base with my mattress?

Not always. But your existing base should be in good condition, provide adequate support, and meet the manufacturer's requirements for the warranty to be valid. Ask specifically about what your new mattress needs.

How do I know if a mattress associate is steering me wrong?

Watch for signs they're ignoring your stated needs, jumping immediately to the most expensive options, or unable to explain why a specific mattress suits your sleep profile. A good associate asks questions before recommending anything.
