What to Look for Before Buying the Best Mattress For Ikea Hemnes Daybed
Find Your Need
The Ikea Hemnes Daybed is a unique piece of furniture because it transforms from a single twin bed (or sofa) into a double bed. This functionality dictates your mattress choice. Most users need two mattresses. When the bed is closed, the mattresses stack on top of each other. When open, they lay side-by-side. If you only plan to use it as a single bed, you might opt for one higher-quality, thicker mattress. However, for full functionality, you need two mattresses that are compatible with stacking.
Budget
Mattresses for daybeds typically cost less than standard bedroom mattresses, but buying two adds up. Expect to spend between $100 and $200 per mattress for decent quality foam. Setting a budget of $250-$400 for the pair is realistic for a setup that will last. While you can find cheaper options, they often lack the density required to prevent bottoming out when sitting.
Key Features
The most critical feature is thickness. The Hemnes frame has a backboard; if your stacked mattresses are too high, they will cover the back rail and look awkward. The sweet spot is generally 5 inches per mattress (10 inches total when stacked).
- Dimensions: Standard Twin (38x75 inches) usually fits, but it can be a tight squeeze. Some users prefer “Cot” sizes (around 33 inches wide) for an easier fit, though this leaves a gap when the bed is fully open.
- Material: Memory foam is preferred over springs because it is lighter to move and handles the “seam” between the two mattresses better when extended.
Quality & Durability
Since daybeds are often used for sitting, the edge support and foam density are vital. Low-density foam will sag quickly where people sit the most. Look for “high-density” base foam descriptions. A mattress with a removable and washable cover is also a significant indicator of quality and practicality, especially for guest rooms or kids’ rooms.
Brand Reputation
Stick to established brands that offer warranties and have a history of producing safe sleep products. Brands like Milliard and Fortnight Bedding specialize in these niche sizes and have track records for durability. Look for CertiPUR-US certification to ensure the foam is made without ozone depleters or heavy metals.
Portability/Size
You will be moving these mattresses often—stacking them, unstacking them, and changing sheets. Weight matters. A foam mattress is significantly lighter than a coil hybrid, making the transition from sofa to king bed much easier for one person to handle alone.
Is it A Wise Decision to Buy mattress for ikea hemnes daybed?
Investing in the correct mattresses for your Hemnes daybed is absolutely a wise decision because it unlocks the full potential of the furniture. Without the right mattresses, the Hemnes is just a large, uncomfortable frame. The correct set allows you to have a stylish sofa by day and a sprawling King-sized bed for guests by night.
Compared to buying a dedicated sofa bed (which often has uncomfortable bars and thin springs) or a permanent guest bed (which takes up valuable room space), a well-outfitted daybed offers superior versatility. While the initial cost of buying two mattresses might seem high, the long-term benefit of having a multi-functional room outweighs the expense. It transforms an office or nursery into a fully capable guest suite instantly.
What Is the Best Way to Choose mattress for ikea hemnes daybed?
Selecting the right product involves a systematic approach to ensure you don’t end up with returns.
- Measure Your Frame: Even though Hemnes is standard, assembly variations occur. Measure the inner width and the height of the back rail.
- Decide on Usage: Will this be slept on nightly or just twice a year? For nightly use, invest in the Gel-Infused or thicker options. For occasional use, the standard foam is sufficient.
- Check the Height: Ensure that 2 x (Mattress Thickness) is less than or equal to the back rail height minus a few inches for pillows. A 5-inch mattress is usually the safest bet.
- Read Material Specs: Avoid generic “foam” if possible; look for specific layers like “memory foam topper” and “high-density base.”
- Consider the Gap: If you buy standard twins, they fit tight. If you buy narrower cot sizes, they fit easily but leave a small gap when open. Decide which annoyance you prefer to deal with.
FAQ
What is the best mattress thickness for an Ikea Hemnes daybed? The ideal thickness is 5 inches. This allows two mattresses to be stacked (totaling 10 inches) without exceeding the height of the back frame or making the “sofa” seating position uncomfortably high.
How much should I spend on a mattress for my daybed? For a good quality 5-inch memory foam mattress, expect to spend between $100 and $180 per mattress. Since you likely need two, budget around $250-$350 total for a complete set.
What features are most important in a daybed mattress? Thickness (profile height) and weight are most important. You need a mattress light enough to move easily and thin enough to stack properly. A removable cover is also a highly valuable feature.
How do I maintain my daybed mattresses? Rotate them regularly so they wear evenly, especially if you sit on one spot often. Use mattress protectors to keep them clean, and wash the removable covers if applicable.
Are expensive memory foam mattresses worth it for a daybed? For a primary bed, yes. For a guest daybed, mid-range options like Milliard offer the best value. You don’t need luxury hybrid mattresses for a trundle setup; they are often too heavy and thick.
What brands make the best mattresses for the Hemnes? Milliard is a top contender because they manufacture specific sizes that align perfectly with trundle and daybed requirements. Fortnight Bedding is excellent for higher-end, cooling options.
How long do these thin foam mattresses typically last? With moderate use, a high-density foam mattress for a daybed should last 5-7 years. Heavy daily sitting may compress the foam faster than sleeping would.
Can I find good mattresses for the Hemnes on a budget? Yes. The Milliard foam options are specifically designed to be budget-friendly while providing adequate support. They cut costs by using simple foam construction rather than complex coil systems.
Final Verdict
After extensive review, the Milliard 5 Inch Memory Foam Twin stands out as the best mattress for ikea hemnes daybed setups. Its dimensions align perfectly with the frame, and the 5-inch profile allows for seamless stacking without compromising the aesthetic of the furniture. It offers the best balance of comfort, weight, and price.
For those concerned about space or finding the twin fit too tight, the Milliard 5 Inch Memory Foam Cot is a fantastic alternative that makes converting the bed easier.
If you have hot sleepers or want a more premium feel, the Fortnight Bedding Gel Infused Cot is the superior choice for temperature regulation.
To get the most out of your daybed, we recommend purchasing two matching mattresses to ensure a level sleeping surface when the bed is extended.
