01What a Designer's Bedroom Reveals About Sleeping Well

Interior designers live in a strange paradox: they spend their careers making spaces beautiful for other people while their own home becomes a kind of unfiltered expression of what they actually believe. Lisa Kahn — founder of the Kahn Design Group and a designer known for gracious, carefully considered residential interiors — is one of the rare people who's thought deeply about what a bedroom should actually do.

Her philosophy is worth paying attention to, not because of the aesthetics, but because of the functional intelligence behind it.

02Start with What the Room Is For

Lisa's starting point isn't color or furniture — it's intent. She describes her bedroom as "the most sacred space" in her home: a place for sleep, reading, meditation, and genuine rest. Not a second office. Not a media room. Not a catch-all for things that don't have another home.

Her design philosophy is built around a set of values she articulates explicitly: "timeless investments, elegant grace, relaxing comfort, peace, inspiration, integrity of materials, environmental sensitivity, nurturing energy, strength of character."

That's a long list — but notice what's not on it. Fast. Trendy. Impressive. Stimulating.

The bedrooms that genuinely help people sleep well tend to share these qualities: they feel settled, not busy. They're curated rather than accumulated. They prioritize comfort over appearance, even when appearance is obviously considered.

What this means practically

  • Define what you actually use your bedroom for — and remove what doesn't belong there
  • Work materials in the bedroom (laptops, paperwork, bags) are a documented disruptor of sleep quality; they blur the psychological boundary between work and rest
  • A bedroom that serves too many functions serves none of them well

03Materials That Matter

Lisa's design choices emphasize what she calls "integrity of materials" — choosing things that are genuinely what they claim to be, that age well, and that don't compromise the environment she's trying to create.

This has direct relevance to sleep quality. The materials in your bedroom affect temperature regulation, allergen load, and even air quality.

Bedding

Natural fibers — cotton, linen, bamboo-derived fabrics — breathe significantly better than synthetic alternatives. Lisa's preference for layered duvets and feather down is rooted in the same principle: natural insulation that responds to body temperature rather than trapping it.

  • Percale cotton — crisp, cool, durable. Best for warmer sleepers.
  • Sateen cotton — smoother hand feel, slightly warmer. Good for those who sleep cold.
  • Bamboo lyocell — thermoregulating. Excellent for people whose temperature varies through the night.
  • Linen — highly breathable, softens with use. Best for warm climates.

Furniture and finishes

Particleboard and synthetic-finish furniture off-gasses VOCs — particularly formaldehyde — which can irritate airways and affect sleep quality over time. Solid wood and responsibly sourced materials perform better over the long run, both in durability and indoor air quality.

04The Bedtime Ritual That Works

Lisa's evening routine is genuinely effective — not because it's elaborate, but because it consistently signals to her nervous system that the day is ending.

She avoids screens before bed. Not because of a rule, but because she knows they engage her imagination in ways that make it hard to turn off. Instead: a lavender-scented bath, herbal tea, and opening the curtains to let in moonlight.

There's more sleep science in that routine than it might appear:

  • Warm bath before bed — the drop in core body temperature after getting out of a warm bath mimics the physiological signal that precedes natural sleep onset. It's one of the most evidence-backed sleep interventions that isn't a supplement or medication.
  • Avoiding screens — blue light from phones, TVs, and computers suppresses melatonin production and delays sleep onset. The effect is real and measurable.
  • Herbal tea — the ritual and warmth both matter. Chamomile, valerian, and passionflower have mild calming properties; the act of making and drinking something warm is itself a reliable wind-down cue.
  • Opening curtains to moonlight — natural low-level light at night doesn't have the disruptive effect of artificial light. The psychological sense of connection to the outdoors also matters; it's calming in a way that a blank wall simply isn't.

"Together they relax my body and my mind. I throw back the sheers on the sliding doors and let the moonlight pour into my room, which makes me feel like we're cocooned in a magical blanket." — Lisa Kahn

The takeaway isn't to copy this routine exactly. It's to have a routine — a consistent sequence of low-stimulation activities that you do in the same order every night. Your brain learns to associate the beginning of that sequence with sleep, making the transition easier over time.

05On Choosing a Mattress

As someone who designs bedrooms professionally and thinks carefully about every element of a sleeping environment, Lisa's mattress preferences are worth noting.

She sleeps on a medium-firm latex mattress with a pillow top. She's a combination sleeper — stomach, back, and side — which means she needs a mattress that works across multiple positions.

Her choice reflects several things that hold up well as general advice:

  • Medium-firm is the most broadly effective firmness level — it supports spinal alignment without creating excessive pressure on the hips and shoulders for side sleeping, while still providing enough surface response for stomach sleeping.
  • Latex sleeps cooler than memory foam and has a more responsive feel — it conforms to the body but doesn't create the "stuck" sensation some people experience with dense foam.
  • A pillow top adds comfort without sacrificing support — it's a comfort layer that compresses under pressure rather than replacing the support core.

After 8 years with the same mattress, Lisa still speaks about it with appreciation — which says something about the value of making a considered choice rather than a convenient one.

If you're due for a new mattress or simply unsure whether yours is still serving you well, our team at any LA Mattress Store location can walk you through the options. We carry latex, memory foam, and hybrid mattresses across a wide range of firmness levels, and our 120-night comfort guarantee means you have real time to know if you got it right.

06Why Making Your Bed Matters

Lisa makes her bed every morning, and her explanation is more useful than the typical "discipline" framing:

"Making my bed makes me feel as though I've closed the chapter on sleep and opens the next one of the new day."

This is about psychological transitions, not tidiness. Sleep research consistently shows that the bedroom environment affects the mind's ability to shift between rest and wakefulness. A made bed signals a completed rest period and a clear start to the day — in the same way that a wind-down routine signals the end of it.

There's also something to the reverse: coming home to an unmade bed (as Lisa notes she dislikes) reactivates the in-between feeling of a half-finished rest, which can make it harder to wind down fully that night.

07Key Takeaways

  • Define what your bedroom is for — and defend that boundary. Rest-first spaces genuinely help you sleep better.
  • Natural materials in bedding, mattresses, and furniture reduce allergens, regulate temperature better, and off-gas fewer chemicals.
  • A consistent pre-sleep ritual works because the brain learns sequences — the routine becomes the cue.
  • A warm bath 1–2 hours before bed is one of the most effective non-supplement sleep interventions available.
  • Screens before bed are a genuine problem — not just a piece of wellness advice to ignore.
  • Your mattress matters more than almost any other element in the bedroom. Make a considered choice and give it real time to work.
  • Making your bed isn't about neatness — it's about psychological transitions that make both waking and sleeping easier.
