The IKEA Hemnes daybed is arguably one of the most versatile pieces of furniture in the modern home design canon. It bridges the gap between a structured sofa and a functional guest bed with a classic silhouette that fits farmhouse, coastal, and Scandinavian interiors alike. However, as an interior designer, I see clients make the same error repeatedly: they invest in the frame but treat the mattress for daybed ikea configurations as an afterthought.
Choosing the wrong mattress doesn't just affect sleep quality; it ruins the visual proportion of the piece and breaks the functionality of the pull-out mechanism. If you go too thick, the back panel disappears. Too thin, and your guests feel the slats. This guide will help you curate the perfect balance of comfort and aesthetics.
Key Features to Look For
- Thickness Limit: For the Hemnes, stick to 4–5 inches (approx. 10-12 cm) per mattress. Anything thicker will look clumsy when stacked.
- Material Weight: High-density foam is superior to springs for daybeds, as you need to lift and move the mattresses frequently.
- Firmness Level: Opt for Medium-Firm. Since daybeds are used for sitting, a soft mattress will sink too much, making it look messy and feel unsupportive.
- Size Specifics: Ensure you buy two Twin mattresses (38" x 75"), not Twin XL, to ensure a flush fit within the frame.
Solving the "Stacking" Dilemma
The unique value proposition of the ikea hemnes daybed mattress setup is its ability to transform from a single twin to a king-size bed. This requires two mattresses. When the bed is in "sofa mode," these mattresses are stacked on top of one another.
This is where the design mathematics become critical. If you purchase two standard 8-inch mattresses, your seat height jumps to 16 inches plus the frame height. This creates a "Princess and the Pea" visual effect that dwarfs the armrests and hides the beautiful back detailing. To maintain the correct visual scale, you must prioritize low-profile mattresses. The best mattress for ikea hemnes daybed is almost always a resilient foam option that maintains a low profile without bottoming out.
Material Selection: Foam vs. Spring
When selecting a mattress for hemnes daybed, weight is a functional consideration often overlooked until you are trying to convert the bed at 11 PM for a guest. Spring mattresses are heavy and rigid. Moving a heavy spring mattress from the stack to the pull-out trundle is cumbersome and risks scratching the painted finish of the daybed frame.
I invariably recommend high-quality poly-foam or latex for these frames. Not only are they lighter, but they also sit flush against each other when extended into a King bed. Spring mattresses often have rigid edge piping that creates an uncomfortable "gutter" or gap between the two mattresses when sleeping. Foam compresses slightly, creating a more seamless surface.
Styling for a Luxury Look
Once you have the mattress for ikea hemnes daybed sorted, the challenge is styling. Because you are essentially stacking two mattresses, the front edge can look utilitarian. To elevate the look, use a structured, fitted coverlet that tucks tightly under the bottom mattress. Treat the backboard as a canvas for textiles; use three large Euro shams to hide the depth of the mattress stack and provide ergonomic back support for sitting.
My Personal Take on mattress for daybed ikea
I have specified the Hemnes for countless guest rooms, and I actually have one in my own home office. Here is the unpolished truth that product descriptions won't tell you: the "sliding" issue is real.
When you stack two foam mattresses (I use the IKEA Åsvang, formerly the Malfors), the top one tends to slide forward over time as people sit on it. It creates a sloppy overhang that drives me crazy. My personal fix? I applied strips of heavy-duty velcro to the underside of the top mattress cover and the top of the bottom mattress cover. It keeps them perfectly aligned in stack mode.
Also, a warning regarding sheets: When the bed is extended to a King, standard King sheets fit, but they tend to bunch in the middle because the mattresses move slightly apart during the night. I strongly suggest using a "bed bridge" connector—a piece of foam that fills the crack—and a thick mattress protector to span both twins. It makes the ikea daybed mattress size feel like a true luxury King rather than two cots pushed together.
Conclusion
The Hemnes is a design workhorse, but it requires a strategic approach to upholstery. By selecting the correct ikea hemnes daybed mattress options—specifically focusing on low-profile, medium-firm foam—you ensure the piece functions smoothly and looks intentional. Don't let a bulky mattress compromise the clean lines of your room.
Frequently Asked Questions
What is the best mattress thickness for the IKEA Hemnes daybed?
The ideal thickness is between 4 and 5 inches per mattress. This allows the stacked height to remain around 10 inches, which keeps the seating ergonomic and ensures the backrest remains visible.
Can I use a standard Twin mattress for the Hemnes daybed?
Yes, standard Twin mattresses (38" x 75") fit perfectly. Avoid Twin XL sizes, as they will overhang the frame and prevent the drawers from looking balanced.
How do I make the two mattresses comfortable when used as a King bed?
To avoid the gap between the two mattresses, use a bed bridge connector and a high-quality, padded King-size mattress protector to cinch them together. This creates a unified sleeping surface.
