How to Test a Mattress in the Showroom: A 10-Minute Checklist

October 7, 2026

By the Cambridge Beds & Furniture team, 199 Thames Street, Morrinsville. Updated September 2026.

To test a mattress properly in a showroom, lie on it for at least five to ten minutes in the position you actually sleep in, with your own pillow if you can bring it. Check that your spine stays straight, that your shoulders and hips aren't pressed hard into the surface, that you can roll over easily, and that the edge holds you when you sit on it. If you share a bed, test it together. Most people only sit on the edge and press the top with a hand, which tells you almost nothing about how you'll sleep. This checklist walks you through a proper test you can do at our Morrinsville showroom, or anywhere else.

Why should I test a mattress in person?

Mattress feel is personal. Two people of different weights can lie on the same mattress and describe it completely differently. Words like "medium" and "plush" help narrow the field, but they aren't the same across every brand and range. The only reliable way to know if a mattress suits you is to lie on it.

You'll spend around a third of your life on your mattress, and most people keep one for many years. Ten minutes of testing is a small investment for that.

What should I bring when I go mattress shopping?

Your own pillow. Pillow height changes how a mattress feels, especially for side sleepers.
Your partner, if you share a bed. Testing alone doesn't tell you how you'll sleep together.
Comfortable clothes and shoes you can slip off easily.
Your bed size and room measurements, so you only test sizes that fit. Our bed size guide lists the NZ sizes.
A note of what's wrong with your current mattress, for example "sore lower back", "too hot", "I feel my partner move".
A budget range, so you can focus on the right part of the range.

The 10-minute mattress test, step by step

Minute 1: Sit on the edge

Sit on the side of the mattress as if you're putting on socks. Does the edge hold you, or does it sag and tip you forward? Good edge support matters for getting in and out of bed, and it makes more of the surface usable. It's especially important for older people and anyone with sore knees.

Minutes 2 to 4: Lie in your main sleeping position

Lie down the way you actually fall asleep, not flat on your back looking at the ceiling (unless that's how you sleep). Stay still for at least two minutes. Your body needs a little time to settle before you can feel whether the mattress is supporting you or just feels soft at first.

Minutes 5 to 6: Check your spine

If you've brought a partner or friend, ask them to look at your spine from behind while you lie on your side. It should look roughly straight from neck to lower back, not sagging at the hips or bent up at the shoulder. On your back, slide a hand under the small of your back. If there's a big gap, the mattress may be too firm for you. If you can't get your hand in at all, it may be too soft.

Minute 7: Roll over

Turn from one side to your back to the other side, the way you would at night. Does it take effort, as if you're climbing out of a hole? Or is it easy? A mattress that's too soft can make turning hard work. You should be able to move without struggling.

Minute 8: Try your other positions

Most people change position several times a night. If you start on your side but wake on your back, test both.

Minute 9: Test with your partner

Lie down together. Have one person roll over or get up while the other stays still with eyes closed. How much do you feel it? If one of you is a restless sleeper, this test matters a lot. Check too whether you roll toward each other in the middle.

Minute 10: Get up

Get up the way you would in the morning. Was it easy? Did the edge support you? Then compare with the next mattress on your shortlist.

How firm should my mattress be?

It depends mainly on how you sleep and your body weight. As a general guide:

You sleep mainly on your...	Usually suits	Why
Side	Medium mattresses or plush	Shoulders and hips need to sink in a little so your spine stays straight
Back	Medium-firm mattresses	Supports the lower back without too much sink
Stomach	Firm mattresses	Stops the hips dipping, which can strain the lower back
Mix of positions	Medium	A balance of support and comfort as you move

Heavier people often prefer a firmer feel, and lighter people a softer one, because the same mattress compresses differently under different weights. Use this as a starting point, then trust what you feel when you lie down.

Our range is labelled by feel, which makes comparing easier. You can lie on the Dreamland Lincoln Medium and Lincoln Firm, or Spine Serene Medium and Spine Serene Firm, back to back. Not sure where to start? Browse all beds and mattresses and filter by comfort level.

What are the most common mattress testing mistakes?

Only sitting on it. Sitting tells you about the edge, not about how you'll sleep.
Lying for ten seconds. First impressions favour soft mattresses. Give each one a few minutes.
Lying on your back when you sleep on your side. Test in your real position.
Testing too many. After six or seven, everything starts to feel the same. Narrow it to three.
Shopping when exhausted. If you're very tired, everything feels comfortable.
Choosing for your partner. Both of you need to lie on it.
Ignoring the base. An old, sagging base can make a new mattress feel wrong at home.

How do different mattress types feel when you test them?

Knowing what to expect helps you make sense of what you feel:

Bonnell spring: connected coils that feel bouncy and even. Often used in budget mattresses. You may feel more movement from a partner.
Pocket spring: individually wrapped springs that move separately, so they respond more to your shape and pass on less partner movement.
Memory foam: slower to respond, with a "sinking in" feel that some people love and others find hard to move on.
Latex: springier and quicker to respond than memory foam, with a buoyant feel.
Pillowtop: an extra comfort layer on top that adds softness at the surface. Check it still supports you underneath.

Ask which construction each mattress on your shortlist uses, then pay attention to how that feels during the roll-over and partner tests.

How should I test a mattress if I have back pain?

Take extra time on the spine check and the roll-over test, and try at least one medium-firm and one firm option. Notice whether any position makes your usual pain worse after a few minutes. Everyone's back is different, so there isn't one "best" mattress for back pain. If you have ongoing pain, ask your doctor or physio what kind of support they recommend, then use this checklist to test options against that advice.

Testing tips for heavier or lighter bodies

Body weight changes how a mattress feels. A heavier person will press further into the comfort layers, so a mattress that feels medium to a lighter person can feel soft to them. Heavier sleepers often find firmer options and strong edge support more comfortable. Lighter sleepers may find a firm mattress hard on the shoulders and hips. If you and your partner are quite different in weight, test together and consider a pocket spring mattress, which responds to each person separately.

How do I test a mattress for a child or teenager?

Bring them with you and let them lie on it, because kids are honest about what's uncomfortable. For children, a medium, supportive mattress is usually a good choice rather than very soft foam. Teenagers who have had a growth spurt may need a longer bed, such as a king single mattress at 202 cm long. Check they can lie flat without their feet hanging over the end. Shopping for bunks? See our kids bunk beds.

What if I'm pregnant?

Needs can change through pregnancy, and many people move to side sleeping. Test mainly on your side, with a pillow between your knees if that's what you use at home. Your midwife or doctor can advise on comfort and positioning.

Testing a mattress for a guest room

For a spare room used a few times a year, you don't need to test as long. Check the edge, lie on your back and side for a minute each, and make sure it's comfortable for an average adult. A budget option such as the SleepTime Kyro Bonnell mattress is often enough for occasional guests. Planning for Christmas visitors? Read our guest bed options for Christmas.

How long should I lie on a mattress in the store?

At least five minutes in your main position, and ten minutes on your final choice. It can feel awkward lying still in a showroom, but it's normal and it's exactly what the beds are there for. Take your time.

Should I test with my own pillow?

If you can, yes. A pillow that's too high or low for you can make a good mattress feel wrong, especially on your side. If you don't bring one, ask to try a few of ours so you're testing with something close to what you use at home. Our pillows range from low-profile to tall and adjustable.

How do I test a mattress to see if it will be too hot?

It's hard to judge heat in a few minutes, but a few clues help. Notice whether the surface feels warm under you after five minutes, or whether you sink in so deeply that you feel enclosed. Ask about the comfort layers, because some foams hold more heat than others. If you're a hot sleeper, our guide to the best mattress for hot sleepers explains what to look for.

What questions should I ask the salesperson?

What's the difference between this mattress and the next one up in price?
Is this mattress available as mattress only, or with a base?
How thick is it, and will it suit my current base or bed frame?
Can it be used on an adjustable bed base?
What warranty comes with it? (Our mattress warranty terms are online.)
How does your comfort guarantee work if it doesn't feel right at home?
What will delivery cost to my address, and can you take my old mattress away?
What payment options do you offer?

What if the mattress feels different at home?

That's normal for the first few weeks. Your body has adjusted to your old mattress, and a new one can feel firmer or softer than it did in the showroom. Give it time before you judge it.

If it still doesn't feel right after that, our 60-Night Comfort Guarantee lets you exchange your new mattress. The page explains the terms. Your rights under the Consumer Guarantees Act also apply.

How much should I spend on a mattress?

Set a range before you test, so you don't fall for a premium mattress you can't afford. In our range, queen mattress and base sets start at $699, most everyday mid-range sets sit between $1,000 and $2,200, and premium models go higher. Test at least one mattress just above and one just below your range, so you know whether the extra money makes a difference you can feel. Watching the budget? Check our mattress and furniture sale first.

If the right mattress is a bit over budget, you can spread the cost with Afterpay, GEM Visa, Finance Now or Q Mastercard. See our finance options. We also prepare WINZ quotes.

Do I need a new base as well?

Test the mattress on the kind of base you'll use it on. If your base at home sags, creaks or is more than about ten years old, a new mattress on it may feel very different from the showroom. Many of our mattresses come as mattress only or as a set with a base, so ask our team to show you the combinations.

When is the best time to go mattress shopping?

When you're rested, not straight after a long day.
At a quieter time, such as a weekday morning, if you want to take your time.
Before your old mattress fails completely, so you're not choosing in a rush.
When there's a sale on, if the model you want is included.

Why buy from a showroom instead of online?

Buying online can be convenient, but you can't lie on a photo. In a showroom you can compare several mattresses in a few minutes, test with your partner, and ask questions face to face. You also know exactly where to go if something needs sorting after you buy. That's the main reason people drive to Morrinsville from Hamilton, Cambridge, Te Aroha and Matamata.

What should I do after I've chosen?

Write down the exact model and size so there's no mix-up on the order.
Check the base. Decide whether you're buying a new one or keeping yours.
Book delivery and ask about removing your old mattress. See delivery and assembly and old bed removal.
Buy a mattress protector before the first night. It keeps the mattress clean and can matter for warranty. Browse our bedding range.
Give it a few weeks. Your body needs time to adjust.
Look after it. Rotate it as the care instructions say. Our mattress care guide covers the basics.

The short version

Bring your pillow and your partner. Lie in your real sleeping position for at least five minutes. Check your spine, try rolling over, sit on the edge and get up the way you would in the morning. Narrow it down to three, compare them back to back, and pick the one where you forget you're lying on a mattress in a shop. That's usually the right one.
