The pillow that keeps your neck straight on your side.

Why your shoulder and neck ache
On your side, a thin pillow bends your neck all night.
Side sleeping is the most common position and the hardest on a pillow. Your shoulder lifts your body off the mattress and leaves a gap of a few inches between the bed and your head. A pillow that is too thin or too soft lets your head sink into that gap, so your neck bends down toward the mattress and your spine kinks at the neck for hours. Enough firm loft fills the gap and holds your head level with your spine, which is the neutral line your neck and shoulder want.
A dropped head is why your neck and shoulder hurt by morning.
The gap is only a few inches. Closing it wrong strains everything above your shoulder, all night long.
01Your shoulder lifts your head a few inches off the mattress.
02A thin pillow lets your head drop into the gap.
03Your neck bends down and your spine kinks for hours.
04You wake with a sore neck and a stiff shoulder.
Fill the gap with enough firm loft and your head sits level with your spine all night. The neck holds its neutral line, the shoulder carries its normal weight, and the morning soreness eases off, usually within the first week or two.
How each one holds your loft
Three ways to hold a tall loft on your side.
Tallest, firmest loft
Build it up, and it holds that height.
Buckwheat is the easiest fill to get right for side sleeping, because you control the loft by the handful. Add hulls until the pillow fills the gap between your shoulder and your head, and they interlock and hold at that height, so your head does not sink through the night the way it does into foam. At about 8 pounds the pillow stays planted where you set it, and the loose hulls let air move through, so the firm, tall support comes without trapped heat. We polish them smooth before they go in, cutting the rustle by up to 68%.

Dense and tall
Dense enough to keep a high loft for years.
Cotton is the densest fill we make, and density is what side sleepers need. Packed full, it builds the tall loft that fills the gap to your shoulder, and because the fiber is so dense it holds that height for 3 to 5 years instead of packing into a flat disc in months the way a softer pillow does. It is GOTS Certified Organic from fill to thread, so the surface against your face all night is clean cotton. There is no break-in and no unusual feel, so it works from the first night.

It keeps the loft and springs back.
Latex holds a tall loft and springs back as you move, so your head stays up at the height you set instead of sinking into the gap. Our slow-pour Dunlop is dense and springy, tapped from rubber trees in Sri Lanka and poured slowly so the density evens top to bottom and it holds its shape for 5 to 8 years. You get the height side sleeping needs with a softer, more forgiving surface than buckwheat, tested to OEKO-TEX Standard 100 Class 1, the strictest grade.

Why your old pillow fails on your side
A soft, flat pillow leaves your head in the gap.
The pillow most people already own is too thin for side sleeping. Down and cheap synthetic fills feel fine on your back but flatten under your head the moment you turn onto your side, so your head drops into the shoulder gap and your neck bends. A fill that builds a tall loft and holds it, whether it molds and locks like buckwheat or springs back like latex, keeps your head up where your spine runs straight.

The ones we hear most.
Straight answers on side sleeping.
What loft do side sleepers need?
Enough to keep your head level with your spine, which for most side sleepers is a taller pillow than they expect, often 4 to 6 inches. The wider your shoulders, the more loft you need. Every Circadian pillow adjusts, so you build it to the exact height your shoulder needs and leave it.
What is the best pillow for side sleepers?
A firm pillow with a tall, adjustable loft. Buckwheat is the top pick because you build it to your exact height and the hulls lock there all night. If you want the same height with a softer feel, dense cotton or springy latex both hold a high loft.
Why do I wake up with a sore shoulder?
Usually because your pillow is too thin. When your head drops into the gap between your shoulder and the mattress, your neck bends and your shoulder carries the strain all night. A taller pillow that fills the gap keeps your head level and takes the load off the shoulder.
Are soft pillows bad for side sleeping?
Soft is fine as long as it is tall enough and holds its height. The trouble with most soft pillows is that they flatten under your head, so you lose the loft halfway through the night. Kapok and wool work for side sleeping if you keep them well stuffed, while buckwheat and cotton hold their loft on their own.
Can I adjust the height?
Yes, that is the point. Every Circadian pillow has a full-length zipper and ships a little overstuffed, so you add or remove fill until your head sits level with your spine on your side, then leave it there. Keep what you take out to add back as the fill settles.
