Your complete, practical guide to moving any mattress upstairs safely β from twin beds to king-sized mattresses, tight staircases to spiral flights. Written by Queensland's furniture experts.
To get a mattress upstairs: (1) Measure your stairs and mattress first. (2) Clear the entire path. (3) Wrap the mattress in a protective bag or plastic. (4) Stand the mattress on its long edge vertically with one person at the top and one at the bottom. (5) Use moving straps or forearm forklifts to distribute weight. (6) Take one step at a time, communicating constantly. (7) Angle diagonally at tight corners or low ceilings. Never bend a memory foam mattress.
You've just bought a beautiful new mattress from A2Z Furniture β now comes the real challenge. Getting it upstairs. Whether you're dealing with a narrow Queensland terrace staircase, a tight apartment corridor, or a tricky spiral flight, moving a mattress upstairs is one of the most awkward furniture tasks around.
The good news? With the right preparation, the correct technique, and a helping hand, it's absolutely doable. This guide covers every scenario β different mattress types, staircase styles, and the tools that make it safer and easier.
1. Before You Start: Measure Everything
The number one reason mattress moves fail is skipping the measurement step. Before you even touch the mattress, spend five minutes measuring these key dimensions. It could save you hours of frustration.
Measure the staircase width, the floor-to-ceiling height above each step (not just at the top), and any landing or turning point. Write it down and compare with your mattress dimensions before you start.
Australian Mattress Size Reference Chart
Use this table to understand what you're working with. All dimensions are standard Australian sizes as per Choice Australia.
| Mattress Size | Dimensions (cm) | Approx. Weight | People Needed | Difficulty |
|---|---|---|---|---|
| Single | 92 Γ 188 | 25β35 kg | 1β2 people | Easy |
| King Single | 107 Γ 203 | 30β40 kg | 2 people | Manageable |
| Double | 138 Γ 188 | 35β50 kg | 2 people | Moderate |
| Queen | 153 Γ 203 | 40β60 kg | 2 people min. | Challenging |
| King | 183 Γ 203 | 50β75 kg | 2β3 people | Hard |
What to Measure in Your Staircase
- Staircase width β Measure the clear width between walls or balustrades. Standard AU stairs: 900mmβ1200mm.
- Ceiling clearance above stairs β Measure at the lowest point. A queen mattress stood vertically is 203cm β you need at least this much clearance.
- Landing / turning space β Any mid-staircase landing, 90Β° or 180Β° turns, and doorway widths at the top.
- Doorway at destination β Don't forget to check the bedroom doorway width and height too.
- Your mattress dimensions β Know the exact length, width, and thickness before moving.
2. Tools You'll Need
Having the right tools makes moving a mattress upstairs significantly safer and easier. You don't need all of these, but the more you have, the smoother the move.
A furniture dolly is great for moving a mattress across flat floors but is not suitable for staircase use. Leave it at the bottom, use it to wheel the mattress to the foot of the stairs, then transition to manual carrying with straps for the actual stair climb.
3. Step-by-Step: How to Get a Mattress Up Stairs
Clear the Path Completely
Remove every obstacle from the staircase and the path from front door to bedroom. This includes rugs (a major tripping hazard on stairs), shoes, pet toys, cables, and any furniture on landings. Secure pets and keep children out of the area entirely during the move.
Many Queensland homes have a mid-staircase landing or 90Β° turn. Make sure there's space to rotate the mattress there. Measure the turning radius you'll need.
Wrap and Protect the Mattress
Before moving a centimetre, wrap your mattress in a protective mattress bag or thick plastic. This protects it from dirt, scuffs on walls, and moisture. Seal with strong packing tape. If you don't have a mattress bag, wrap tightly in old blankets or moving pads and secure with rope or bungee cords.
Fit Your Moving Straps
Forearm forklifts or moving straps are the best tools for staircase work. Loop them under the mattress so each person has even weight distributed through their forearms rather than hands. This dramatically reduces the risk of dropping and protects your lower back.
Stand the Mattress Vertically
For almost all staircases, the most effective approach is to stand the mattress on its long edge vertically, making it much narrower. One person holds the bottom, the other holds the top. This is sometimes called the "edge carry" method.
Use Proper Lifting Technique
This is critical for avoiding back injuries. According to Safe Work Australia, correct manual handling means:
- Bend at the knees, not the waist
- Keep your back straight throughout the lift
- Lift with your leg muscles (the strongest in the body)
- Hold the mattress close to your body
- Never twist your torso while carrying
- Avoid lifting above shoulder height
Ascend the Stairs: One Step at a Time
This is where communication between helpers is everything. The person at the top guides direction; the person at the bottom provides power. Use a verbal count β "ready, step" β and take one step at a time. Never rush. Take a rest break on any landing. If the ceiling gets low, angle the mattress diagonally (the "sofa pivot").
Navigate Corners and Low Ceilings: The Diagonal Pivot
When the ceiling gets low or you hit a tight corner, you need to pivot the mattress diagonally. Think of it like parking a car β don't try to force it straight through. Instead:
- Angle the mattress 45Β° diagonally in the stairwell
- The person at the top lifts their end toward the ceiling
- The person at the bottom swings their end toward the wall
- Slowly work it through the corner in this "banana" arc
Place and Position in the Bedroom
Once upstairs, lay the mattress flat as soon as possible. If it's a foam mattress, letting it stand vertically for too long can cause uneven settling. Remove the protective wrapping, position on your bed frame, and allow 24β48 hours before sleeping on it if it's a new memory foam mattress that's been boxed.
4. Guide by Mattress Type
Not all mattresses move the same way. The construction of your mattress determines what you can and can't do. Here's what to know for each type.
Memory Foam
Weight: MediumβHeavy
Can you bend it? No β never fold a memory foam mattress. Bending can permanently damage the foam cells and void your warranty.
Technique: Carry vertically on edge only. Use moving straps. Avoid prolonged vertical storage β lay flat as soon as possible.
Innerspring / Pocket Spring
Weight: Heavy
Can you bend it? Some king innerspring mattresses have a hinge in the middle β check with your manufacturer. Otherwise, no bending.
Technique: Carry vertically. King size may have a fold-point β check first. If no hinge, use diagonal pivot method for tight corners.
Latex / Natural
Weight: Very Heavy (latex is dense)
Can you bend it? No β latex mattresses are among the heaviest and should never be bent or folded.
Technique: You may need 3 people for a queen or king latex mattress. Moving straps are essential. Take frequent breaks.
Mattress-in-a-Box
Weight: LightβMedium (in box)
Can you bend it? While rolled, yes. Once unboxed and expanded, treat as memory foam.
Technique: Best option for stairs β carry the box up first, then unbox upstairs. Much easier than moving a fully expanded mattress.
Hybrid (Foam + Spring)
Weight: Heavy
Can you bend it? No β the spring layer prevents bending. Treat like an innerspring mattress.
Technique: Two people minimum, carry vertically. Use moving straps. Extra caution around corners given the added weight.
Air Bed / Adjustable
Weight: Light (when deflated)
Can you bend it? When fully deflated, yes.
Technique: Deflate completely before moving. These are the easiest to get upstairs β carry the deflated mattress and pump it up in place.
- Memory foam mattresses β foam cells will permanently compress
- Latex mattresses β the latex core will crack or tear
- Hybrid mattresses β the coil layer will distort
- Innerspring mattresses without a hinge β border rod will buckle
Bending any of these can void your warranty immediately.

5. Guide by Staircase Type
Straight Staircase (Most Common)
The most straightforward scenario. Stand the mattress vertically, one person top, one bottom, and ascend steadily. Still requires two people for queen and king sizes.
L-Shaped / 90Β° Turn Staircase
The 90Β° turn is where most moves get stuck. Use the diagonal pivot technique: angle the mattress at 45Β° as you approach the landing, pivot it around the corner slowly. One person on each side of the turn helps significantly. Measure the diagonal clearance of your landing before you start β diagonal measurement = β(lengthΒ² + widthΒ²).
U-Shaped / Switchback Staircase
Similar to L-shaped but with two turns. Take it one section at a time. The mattress will need to be manoeuvred around the banister post at the turn β fold it around the post if possible (innerspring with hinge only), or use the diagonal method twice.
Spiral Staircase
The most challenging scenario. According to Gowling Stairs Australia, the recommended approach is to lay the mattress flat against the open side of the spiral and use the handrail as a guide, with two or three people. If the mattress physically cannot navigate the spiral staircase:
- Consider hoisting via a balcony using a rope-and-pulley system
- Hire professional furniture removalists
- Consider a mattress-in-a-box alternative that is easier to carry up
Under Australia's National Construction Code (NCC), residential staircases must have a minimum clear width of 1000mm for new builds. Older Queensland homes and apartments may be narrower. Always measure before purchasing large mattresses.
6. Common Mistakes (And How to Avoid Them)
β DO This
- Measure everything before you start
- Use at least 2 people for queen and king sizes
- Wrap in a mattress bag to protect it
- Carry vertically on the long edge
- Use moving straps for weight distribution
- Wear non-slip, closed-toe shoes
- Take regular breaks at landings
- Communicate clearly with your helper
- Clear the entire path before starting
- Lift with your legs, not your back
β DON'T Do This
- Try to carry a king mattress alone
- Bend or fold a memory foam or latex mattress
- Rush or skip planning the route
- Carry the mattress flat on stairs
- Leave loose rugs or cables on stairs
- Twist your torso while carrying
- Lift the mattress above shoulder height
- Drag the mattress across floors (damages fabric)
- Leave children or pets in the stairway
- Force the mattress if it doesn't fit
7. When to Call the Professionals
Sometimes the smartest move is knowing when not to DIY. Consider professional help when:
- Your staircase or landing is too narrow for the mattress to pass through safely even vertically or diagonally
- You have a spiral staircase that the mattress physically cannot navigate
- The mattress weighs over 60kg (latex or king-size) and you don't have 2β3 capable helpers
- You have a back, shoulder or joint condition that could be aggravated by heavy lifting
- Access is only possible via a balcony (hoisting via rope required)

8. Frequently Asked Questions
Here are the questions our Queensland customers ask most often about moving mattresses upstairs.
It is possible but not recommended. Mattresses weigh between 25β75 kg depending on size and type. A single person risks back injury and mattress damage. If you must go solo, use a mattress sling or forearm forklifts, take it one step at a time, and take regular breaks. For king or queen mattresses, always enlist at least one other person.
No β folding or bending a memory foam mattress can permanently damage the foam layers and void your warranty. Memory foam should always be kept flat or stood upright on its edge. Instead, navigate stairs by tilting it vertically and sliding it edge-on up the steps with two people.
Stand the king mattress vertically on its long edge. With one person at the bottom and one at the top, slide it diagonally along the stair rail. If the ceiling is too low, angle it diagonally (the 'sofa pivot' method). For innerspring king mattresses, some can be gently bent at the hinge point β check with your manufacturer first. Memory foam king mattresses cannot be bent.
The key tools are: a mattress bag or plastic wrap to protect it, moving straps or forearm forklifts to distribute weight, furniture sliders for hard floor areas, and work gloves for grip. A hand trolley/dolly can help across flat surfaces but is not suitable for stairs.
It depends on the retailer. Many Australian mattress retailers deliver to the front door or ground floor only. At A2Z Furniture, we offer delivery across Queensland β contact your nearest store to discuss delivery options and room-of-choice placement. Our team can advise on what is included for your specific order.
Measure three key dimensions: (1) the clear width of your staircase between walls or balustrades, (2) the floor-to-ceiling height above the stairs at the lowest point, and (3) any landing or turning space. Australian standard staircases are typically 900mmβ1000mm wide. A queen mattress stood vertically is 203cm tall, so you need at least that in ceiling clearance, or you'll need to angle it diagonally.
Spiral stairs are the hardest scenario. Lay the mattress flat against the open side of the spiral flight and use the handrail as a guide. Two or three people are essential. Go very slowly, communicating at each step. If the mattress physically cannot navigate the spiral, consider hoisting it via a balcony using a rope-and-pulley system or hiring professional furniture removalists.
The safest method is: clear the staircase completely, use two people, stand the mattress on its long edge vertically, use moving straps to create handles, bend your knees and lift with your legs (never your back), take one step at a time, and communicate constantly with your helper. Wear non-slip footwear and never rush.
