BioCrystal™ Pillows Are Live: Meet the Classic and the Side Sleeper

Layla Sleep’s BioCrystal^™ Pillows are officially available today, in two shapes. The Classic BioCrystal^™ Pillow is $139 (down from $179) and suits back and stomach sleepers, while the BioCrystal^™ Side Sleeper Pillow is $149 (down from $189)* and suits side and combo sleepers. Both feature CrystalCore^™ cooling, adjustable loft, and a 30-night trial.

If you’ve been following along since we first started talking about what happens when 16 natural crystals get milled into a fine mixture and infused directly into pillow foam, today’s the day you can actually bring one home. (If you’re just catching up, we covered the full story in What Is BioCrystal^™ Technology? This post is the shorter, simpler version: what’s available, which one fits your sleep style, and how to get started.)

Meet the two pillows

Same 16-crystal BioCrystal^™ mixture. Same CrystalCore^™ cooling technology. Two different shapes, because how you sleep matters more than how a pillow looks on the shelf.

BioCrystal^™ Pillow (Classic)

The Classic is a rectangular pillow built for back and stomach sleepers. Its four-layer design lets you remove a layer or two to find the loft that keeps your neck and spine in a comfortable, natural line, somewhere between 4″ and 6″ depending on what feels right for you.

• Price: $139, on sale from $179*
• Best for: back and stomach sleepers
• Loft: 4″–6″, adjustable

BioCrystal^™ Side Sleeper Pillow

The Side Sleeper features a U-shaped cutout designed specifically for the way side sleepers rest. That curved opening gives your shoulder space to settle flat on the mattress while the pillow cradles your neck and keeps your spine supported through the night. The loft runs a little taller here, 5″–7″, because side and combination sleepers generally need a bit more height to stay properly aligned.

• Best for: side and combination sleepers
• Loft: 5″–7″, adjustable

Why it works

The crystal mixture isn’t a coating or a surface treatment. It’s milled directly into the foam and stays there for the life of the pillow. Six of those 16 crystals, grouped together as CrystalCore^™ Temperature Technology, are chosen for their natural thermal conductivity, quietly drawing heat away so it doesn’t build up beneath your head. The BION® Institute in Ljubljana, Slovenia tested BioCrystal^™ technology against standard control foam and found measurable differences in alpha brainwave activity, respiration rate, and body temperature, all pointing toward a deeper, more settled state of relaxation. For a closer look at the research, read “BioCrystal^™ Pillow Benefits: What the Testing Shows.”

Which one is right for you?

Start with your sleep position, and let that guide everything else.

If you sleep on your back or stomach, the Classic is generally the better fit. Its familiar rectangular shape and 4″–6″ adjustable loft make it easy to dial in the height that feels most natural, while the BioCrystal^™ mixture works quietly underneath the surface to support cooling and relaxation.

If you’re a side sleeper, or you tend to shift between positions through the night, the Side Sleeper was made with you in mind. The U-shaped cutout relieves pressure from your shoulder, and the taller 5″–7″ loft keeps your neck properly supported in the position where you spend most of your nights.

Both pillows are adjustable, so there’s room to fine-tune the height once you’ve had a few nights to settle in.

Try it risk-free

Every BioCrystal^™ Pillow comes with a 30-night trial, so you have time to decide if it’s right for you. Sleep on it. Get comfortable with it. If it’s not the right fit or you change your mind, return it at no cost to you.

Both pillows are also OEKO-TEX® certified, meaning the foam and fabric have been independently tested against more than 1,000 regulated substances. That’s one less thing to lose sleep over.

BioCrystal^™ FAQs

They’re live today. Both the BioCrystal^™ Pillow and the BioCrystal^™ Side Sleeper Pillow are available to purchase now, no waitlist or presale sign-up needed.

What’s the difference between the Classic and the Side Sleeper?

The Classic is a rectangular pillow with a 4″–6″ adjustable loft, designed for back and stomach sleepers. The Side Sleeper has a U-shaped cutout and a 5″–7″ adjustable loft, engineered so your shoulder rests comfortably on the mattress while the pillow supports your neck and spine. Both feature the same 16-crystal BioCrystal^™ mixture and CrystalCore^™ cooling technology.

Yes. The sale pricing carries over: $139 for the Classic (down from $179) and $149 for the Side Sleeper (down from $189).

How long is the trial period?

You have 30 nights to settle in with your BioCrystal^™ Pillow and see how it feels. If it’s not the right fit, you can return it within the trial period at no cost to you.
