Quick Answer: The best mattress for a Murphy bed in Canada must be 10 to 12 inches thick and under 60 to 90 lbs (check your specific frame's specifications). All-foam mattresses are the safest choice because they are lightweight, flexible for folding, and do not shift when stored vertically. For Canadian shoppers, the Douglas Original ($799 Queen, 10 inches, ~50 lbs) fits most Murphy bed frames and offers a 365-night trial. If you need a hybrid, the Silk and Snow Hybrid ($1,000 Queen, 12 inches) works in frames rated for 12-inch mattresses but is heavier at ~80 lbs. Avoid pillow-top and mattresses thicker than 12 inches, as they will not fold properly into the wall cabinet.
Talia, Showroom Specialist: "Murphy bed customers always ask the same question: will a regular mattress work? Usually yes, as long as you check the weight limit and stick to 10 to 12 inches thick. We have had customers bring in their frame specs and we match them right on the showroom floor. The key thing most people miss is that you want a mattress with good edge support so it does not shift when the bed folds up."

Murphy Bed Mattress Requirements
A Murphy bed (wall bed) folds up into a wall cabinet when not in use. This creates three requirements that standard bed mattresses do not have to meet.
1. Thickness limit. The mattress must fit inside the cabinet when folded. Most Murphy bed frames accommodate mattresses up to 10 to 12 inches thick. If your mattress is too thick, the cabinet doors will not close, or the mechanism will strain under the extra bulk.
2. Weight limit. The gas piston or spring mechanism that lifts the bed has a rated weight capacity. A mattress that exceeds this weight makes the bed difficult to lift and can damage the mechanism over time. Typical limits range from 60 to 100 lbs for the mattress alone.
3. Vertical storage compatibility. The mattress spends most of its life stored vertically against the wall. It must hold its shape without shifting, bunching, or sliding. Sheets and bedding must stay in place when the bed is raised.
| Requirement | Typical Specification | Why It Matters |
|---|---|---|
| Maximum thickness | 10-12 inches | Cabinet depth limits mattress height |
| Maximum weight | 60-90 lbs (varies by mechanism) | Exceeding limit strains pistons and springs |
| Standard sizes | Twin, Full, Queen (rarely King) | King Murphy beds exist but are uncommon |
| No pillow top | Flat surface required | Pillow tops shift and bunch when stored vertically |
Check Your Frame First
Before buying a mattress, check your Murphy bed frame's documentation for exact thickness and weight limits. Different manufacturers have different specifications. A frame rated for a 10-inch mattress will not safely accommodate a 12-inch mattress, even if the cabinet physically closes. The mechanism is calibrated for a specific weight range.

Best Mattress Types for Murphy Beds
All-foam (memory foam or polyfoam): The best overall choice for Murphy beds. Foam mattresses are lighter than hybrids, flexible enough to fold without damage, and maintain their shape during vertical storage. Memory foam conforms back to its original shape when unfolded. Most Canadian bed-in-a-box brands produce all-foam mattresses in the 8 to 12 inch range that work well in Murphy beds.
Hybrid (foam + pocketed coils): Can work if the weight is within your frame's limit and the thickness does not exceed maximum specifications. Pocketed coils hold their shape well during vertical storage because each coil moves independently. The main concern is weight: a Queen hybrid mattress typically weighs 70 to 90 lbs, which is near or at the limit for many Murphy bed mechanisms.
Latex: Natural and synthetic latex mattresses work well in Murphy beds because latex is resilient and bounces back to shape quickly. However, latex mattresses can be heavy (80 to 100+ lbs for a Queen), so check your weight limit carefully.
Innerspring (traditional coil): Traditional innerspring mattresses with interconnected coils can work but may develop uneven wear over time from vertical storage. The coils can shift within the mattress when stored upright. If you choose innerspring, look for individually wrapped coils (pocketed coils) rather than Bonnell or continuous coil designs.
Vertical Storage: What Happens to Your Mattress
When a Murphy bed is folded up, the mattress hangs vertically. Gravity pulls the materials downward. Over time, this can cause:
- Foam compression at the bottom edge. The foam layers are compressed by their own weight against the bottom of the cabinet. High-density foam (3+ lb/ft3) resists this better than low-density foam (1.5 to 2 lb/ft3).
- Coil shift. In innerspring mattresses, coils can gradually shift downward if not properly encased. Pocketed coils resist this because each coil is individually wrapped.
- Sheet and bedding displacement. Gravity pulls sheets, blankets, and pillows toward the foot of the bed. Murphy bed straps, elastic sheet clips, or specifically designed Murphy bed sheet sets keep bedding in place.
Foam Density Matters
For Murphy bed use, choose foam mattresses with a support core density of at least 1.8 lb/ft3 and comfort layers of at least 3 lb/ft3. Low-density foams (under 1.5 lb/ft3) degrade faster when stored vertically, developing a "lean" or permanent compression on one side. Higher-density foam resists gravity-related compression and maintains consistent support over years of daily folding.

Top Pick: Douglas Original
The Douglas Original is the ideal Murphy bed mattress for most Canadians. At 10 inches thick and approximately 50 lbs, it fits comfortably within standard Murphy bed frame specifications. The medium-firm firmness (6.5 out of 10) works for most sleepers and maintains its shape well during vertical storage. Made in Canada (GoodMorning.com, Edmonton), with a 365-night trial and 15-year warranty.
Budget Pick: Juno
Juno is the most affordable Canadian-made mattress at $499 for a Queen. At 10 inches thick and lightweight (~45 lbs), it fits all standard Murphy bed frames. Juno is made by the same parent company as Douglas (GoodMorning.com) and comes with a 365-night trial. If your Murphy bed is primarily for guest use, Juno offers the best value.
Weight Limits and Mechanism Types
Murphy beds use two main mechanism types, each with different weight tolerances.
Gas piston mechanisms: Most modern Murphy beds use gas pistons (similar to car trunk struts) to assist with lifting and lowering. These are rated for a specific combined weight of mattress and bedding. If you exceed the rated weight, the bed becomes difficult to close and the pistons wear out faster. Replacement pistons cost $50 to $150 per pair.
Spring mechanisms: Older or heavy-duty Murphy beds use torsion springs. These are more forgiving with weight variations but require professional adjustment if the weight changes significantly. Spring mechanisms generally handle heavier mattresses better than gas pistons.
Bedding and Sheets for Murphy Beds
Standard fitted sheets will pull off the mattress when stored vertically. Solutions include:
- Elastic sheet straps: Clips that attach to the sheet corners and wrap under the mattress, keeping the sheet tight during vertical storage. Available for $10 to $20 on Amazon.ca.
- Murphy bed specific sheet sets: Designed with extra-deep pockets and elastic all around (not just corners). Brands like PureCare and BEDGEAR make fitted sheets designed for wall beds.
- Sleeping bag approach: Some Murphy bed users zip their bedding into a sleeping bag-style enclosure that wraps around the mattress. This keeps everything in place regardless of orientation.
- Built-in straps: Many Murphy bed frames include elastic straps that cross over the mattress surface, holding sheets, blankets, and pillows in place. Check if your frame includes these before buying accessories.
Mattresses to Avoid for Murphy Beds
- Pillow-top mattresses: The pillow top shifts and bunches when stored vertically. After a few months, you will notice the pillow top material collecting at the bottom edge.
- Mattresses over 12 inches thick: Many premium Canadian mattresses (Logan and Cove Choice at 13 inches, Douglas Summit at 12.5 inches) are too thick for most Murphy bed frames.
- Mattresses over 90 lbs: Heavy latex or premium hybrid mattresses can exceed mechanism weight limits. A Queen natural latex mattress can weigh 100+ lbs.
- Air mattresses and waterbeds: Not compatible with vertical storage.
- Low-density foam (under 1.5 lb/ft3): Will degrade quickly from vertical storage compression. Budget mattresses with unspecified foam densities are a risk.

Can I use a regular mattress in a Murphy bed?
Yes, as long as it meets your frame's thickness (typically 10 to 12 inches max) and weight limits (typically 60 to 90 lbs). Most Canadian all-foam mattresses at 10 inches thick, including Douglas, Endy, Juno, and Silk and Snow, fit standard Murphy bed frames. You do not need a Murphy-bed-specific mattress.
Does storing a mattress vertically damage it?
A quality mattress with high-density foam (3+ lb/ft3 comfort layers, 1.8+ lb/ft3 support core) will handle vertical storage without damage. Low-density foams can develop permanent compression on the bottom edge over time. Murphy beds are designed for daily folding, and mattresses used in them are expected to handle vertical storage. Most mattress warranties do not exclude Murphy bed use.
What is the best thickness for a Murphy bed mattress?
10 inches is the ideal thickness. It fits all standard Murphy bed frames, is thick enough for comfortable sleep (most Canadian bed-in-a-box brands at 10 inches score well in comfort tests), and is light enough to stay within weight limits. If your frame supports 12 inches, you have more options, but 10-inch mattresses provide the most compatibility.
How do I keep sheets on a Murphy bed mattress?
Use elastic sheet straps ($10 to $20) that clip to the sheet corners and wrap under the mattress, or buy deep-pocket fitted sheets with elastic all around. Many Murphy bed frames also include built-in elastic straps that cross over the mattress to hold bedding in place during vertical storage.
Is a Murphy bed mattress comfortable for daily use?
Yes, if you choose a quality mattress. A Murphy bed sleeps identically to a regular bed when lowered. The only difference is the mattress thickness limitation. A 10-inch Douglas or Endy mattress in a Murphy bed provides the same sleep experience as the same mattress on a regular bed frame. Many Canadians in condos and small spaces use Murphy beds as their primary bed.
