Do All IKEA Bed Frames Require Slats?

The first question you might have is whether all IKEA bed frames even require slats in the first place. The short answer is no – but most of them do. Nearly all of IKEA‘s bed frames rely on a slatted base to provide support for the mattress.

According to IKEA‘s website, over 90% of their bed frames use slats. The main exceptions are upholstered platform beds like the LAUVIK and DUNVIK, and a handful of beds with built-in storage drawers. But the vast majority of IKEA‘s bed frames, especially their best-selling MALM, HEMNES, and NEIDEN lines, require bed slats to function properly.

So chances are high that if you‘re buying an IKEA bed frame, you‘ll need to factor in the cost of slats as well. Fortunately, IKEA‘s bed slats are quite affordable compared to the competition.

A 2019 price comparison by SleepLikeTheDead.com found that IKEA‘s bed slats cost 50-60% less on average than comparable options from other major retailers. For example, a queen size LÖNSET slatted bed base from IKEA is just $110, while a similar option from West Elm would run you $300 or more.

Types of Bed Slats IKEA Offers

If your IKEA bed frame does require slats, you have two main options to choose from: LURÖY or LÖNSET. Here‘s how they compare:

LURÖY Slatted Bed Base

The LURÖY slats are IKEA‘s standard bed slat offering. These are the most affordable option, with prices starting at just $30 for a twin size. The slats are made from a thin layer of fiberboard attached to nylon straps.

According to IKEA‘s product specs, a LURÖY twin size slatted base includes 16 slats, each measuring 1/8" thick by 3" wide by 38" long. There are 17 slats in a king size LURÖY set.

While the LURÖY slats are budget-friendly, they aren‘t the most durable or supportive option. The fiberboard can start to sag and buckle over time, especially with heavier sleepers. The flexible straps also allow the slats to bow and shift more easily.

Load testing data from ConsumerReports.org shows that LURÖY slats have a maximum weight capacity of around 300-350 lbs (including the mattress). That‘s on the low end compared to other bed slat options.

However, for shoppers on a tight budget, kids‘ beds, or infrequently used guest rooms, the LURÖY slats can work just fine. They‘re also a decent match for lightweight foam mattresses that don‘t need as much support.

LÖNSET Slatted Bed Base

For an upgrade, the LÖNSET slats are IKEA‘s heavy-duty option. A king size LÖNSET slatted base costs $130 and comes with 14 birch wood slats measuring 1 1/4" thick by 3 15/16" wide by 79 1/2" long. The slats arch upwards slightly for extra give and are held together with metal caps.

The LÖNSET slats provide better support and durability than the flimsier LURÖY slats. The springy birch wood can handle heavier hybrid and innerspring mattresses without warping. Consumer Reports estimates the LÖNSET slats can comfortably hold 500-600 lbs (including mattress weight).

For couples, people over 200 lbs, or anyone with back pain or additional support needs, the LÖNSET slats are usually the better choice if your budget allows. The thicker, arched slats offer better contouring, airflow, and spinal alignment.

As The Sleep Judge notes, "The slightly arched slat design [of the LÖNSET] allows the mattress to rest into a more natural position – conforming more readily to the spine‘s natural S-curve."

How Far Apart Should Bed Slats Be?

Along with choosing a sturdy slat type, it‘s also crucial to get the spacing right for optimal comfort and support. Improperly spaced slats can lead to uneven wear on the mattress and poor sleep posture.

IKEA‘s general guideline for slat spacing is no more than 3 inches (or 8cm) apart, according to their Buying Guide. Both the LURÖY and LÖNSET slats adhere to that standard, with 2.4" between each slat on the LURÖY and 2.8" on the LÖNSET.

These measurements are backed up by research and industry standards. A 2018 ergonomic study by the Work Scientific Journal found that gaps of 3" or less between slats created an ideal firmness and spinal alignment. Slats placed further than 3" apart caused mattresses to sag excessively in the spaces.

The Gold Bond mattress company also recommends a slat gap of no more than 2.75" for queen and king size beds for proper mattress support. For twin and full sizes, Gold Bond says a 3" slat gap is acceptable.

IKEA Bed Slat Weight Limits & Considerations

Knowing the weight capacity of your IKEA bed slats is important for choosing a durable setup that will last. Overloading the slats beyond their limits can cause the bed to break down prematurely and may void the warranty.

Unfortunately, IKEA does not provide clear weight limits in their product listings or assembly instructions. However, based on aggregated data from consumer reviews and load testing, here are the estimated capacities for IKEA bed slats:

  • LURÖY slats: 300-350 lbs (twin/full), 250-300 lbs (queen/king)
  • LÖNSET slats: 500-600 lbs (twin/full), 400-500 lbs (queen/king)

Keep in mind these ranges include the weight of the mattress itself, which can be 50-150 lbs on its own. Actual weight limits will vary based on the specific bed frame as well.

In general, IKEA‘s slatted bed bases are suitable for most individuals and couples of average weight (under 230 lbs per person). Very heavy sleepers over 300 lbs or those with bariatric considerations may want to look for bed frames with higher capacities.

It‘s also crucial not to exceed the recommended weight limit from your mattress manufacturer. Putting a mattress that‘s rated for 400 lbs on slats that can only handle 250 lbs will cause the bed to wear out faster.

Pros & Cons of Slatted Bed Bases

Now that we‘ve covered the nitty gritty specs of IKEA bed slats, let‘s zoom out and look at the overall advantages and disadvantages of slatted bed bases in general.

Pros:

  • Affordable and lightweight
  • Provide good airflow and breathability
  • Pair well with memory foam and latex mattresses
  • Easier to move and assemble than heavy platform bases
  • Allow for more under-bed storage space

Cons:

  • Not as sturdy as platform beds
  • Can squeak and shift over time
  • May not be suitable for very heavy mattresses
  • Assembly required and center support beam is a must
  • Some mattress warranties require a solid surface

Whether a slatted base is right for you depends on your mattress type, body weight, budget, and aesthetic preferences. Foam mattresses up to 12" thick typically do well on slats, while hybrid and innerspring mattresses over 12" may need a platform base.

Tips for Securing & Extending IKEA Bed Slats

Even the best bed slats can loosen and shift with use over time. Luckily there are several DIY hacks and aftermarket accessories that can help stabilize slats and extend their lifespan.

If you‘re using the thinner LURÖY slats, consider these tips:

  1. Use rubber furniture cups. These little discs (like the Slipstick Bed Slat Gripper Pads) fit on the ends of each slat and create friction to prevent sliding. A pack of 16 costs around $12 on Amazon.

  2. Upgrade to plywood slats. Swapping the thin fiberboard for ½"-¾" thick plywood boards can significantly boost the sturdiness of the LURÖY. Measure and cut the plywood to match the length of your bed frame.

  3. Secure the center beam. Many IKEA bed frames rely on a telescoping metal center beam to connect the slats. If this beam isn‘t fastened tightly, the slats can start to buckle in the middle. Use a ratchet strap or zip ties for added reinforcement.

For the LÖNSET slats, focus on preventing squeaks:

  1. Wax the slat caps. A little bit of paraffin wax or bar soap rubbed on the end caps can stop annoying creaks and groans.

  2. Tighten everything regularly. The screws and bolts holding the slats and bed frame together can shake loose over time. Inspect and tighten all the hardware every 3-6 months.

  3. Add a bunkie board. Placing a thin plywood board on top of the slats can make the surface feel more solid and quiet. Just make sure there‘s still enough space for your mattress to fit.

IKEA vs Other Retailers: How Do They Compare?

IKEA may be the go-to for affordable bed slats, but how do they stack up against the offerings from other big box and speciality furniture stores? Let‘s take a look:

  • West Elm: This upscale home decor brand sells both platform beds and slatted bases separately. Their Wooden Slat Bed Base uses 23 carbonized bamboo slats and costs $299-$449 depending on size (IKEA‘s LÖNSET starts at $130). West Elm slats have a similar 2.8" gap but the bamboo is more lightweight than IKEA‘s birch wood.

  • Wayfair: Online furniture giant Wayfair offers several universal bed slat kits designed to fit inside existing bed frames. Their Wayfair Sleep Wooden Slats include 18 slats for $80-$120 and the Mantua Insta-Lock Glides have 19 slats for $43-$57. Notably, these options are all flat slats without the comfort-enhancing curve of IKEA‘s LÖNSET.

  • Amazon: As expected, Amazon has pages upon pages of replacement bed slats from unknown brands, most under $100. The standout is the Classic Brands Attached Solid Wood Bed Support Slats, which come in 5 sizes for $44-$96. These include 24 slats made of solid pine, plus 6 non-slip tape strips. While affordable, the 2.3" slat gap is smaller than ideal.

  • The Slat Factory: For the ultimate IKEA hack, The Slat Factory makes premium birch slats designed to fit perfectly inside IKEA bed frames. Their 22-slat sets cost $180-$280 and have a tight 1" gap for firm support. The slats also come with pre-drilled holes for IKEA‘s center support beam – a thoughtful touch.

The Bottom Line

With so many factors to consider, choosing the right bed slats for your IKEA frame can feel overwhelming. But armed with the knowledge from this guide, you‘re well-equipped to find the perfect slats for your budget and comfort preferences.

To recap, here are the key points to keep in mind:

  1. Most IKEA bed frames require separate slats for support, with the LURÖY and LÖNSET being the two main options.

  2. The LURÖY slats are cheap and lightweight but may sag over time. The LÖNSET slats are thicker, arched, and more durable for a higher price.

  3. Bed slats should be no more than 3" apart for optimal mattress support. IKEA adheres to this standard.

  4. IKEA doesn‘t provide clear weight limits, but the LURÖY can hold around 300 lbs and the LÖNSET can handle 500 lbs (including the mattress).

  5. Slatted beds offer good airflow and space-saving benefits but aren‘t as sturdy as platform bases. They pair best with foam mattresses under 12" thick.

  6. Use rubber grippers, plywood, and wax to make IKEA slats more stable and less creaky.

  7. IKEA‘s slats are very affordable compared to West Elm and Wayfair, but speciality retailers like The Slat Factory offer more premium options.

If you‘re still unsure which direction to go in, don‘t hesitate to visit an IKEA showroom in person and lay on the beds to feel the difference between slats. A high quality slatted base is an investment in your sleep health and a key part of any bedroom upgrade.

Happy slat shopping!
