This Works Deep Sleep Pillow Spray is an aromatherapy sleep mist built around a three-oil Superblend of lavender, vetiver, and wild chamomile. The UK-founded brand backs the formula with four independent clinical studies on over 600 participants, setting it apart from most competitors in the sleep spray category.
In clinical testing, 89% of users fell asleep faster and 98% woke feeling more refreshed. The formula delivers essential oils at therapeutic concentration to target both sleep onset and pre-sleep anxiety. It’s cruelty-free, vegan, suitable during pregnancy, and holds 4.3 out of 5 stars from 22,765 Amazon reviewers ranking #3 in its category.
This review covers the ingredients, how the spray actually works, what real users report across thousands of reviews, how it compares to Sleep Plus, and whether the $33 price is justified for the results. Here’s everything needed to make a confident purchase decision without guessing.
What Is This Works Deep Sleep Pillow Spray?
This Works Deep Sleep Pillow Spray is an aromatherapy sleep mist from UK brand This Works, formulated to help users fall asleep faster and wake feeling more refreshed. Here’s the thing: the brand doesn’t rely on vague wellness claims. It builds products around sleep science, combining naturally derived ingredients with clinical testing to back each claim.
The product sits in a category of its own. It’s not a supplement, not a diffuser. The spray applies directly to bedding. Users inhale the scent passively as they drift off, with no pills or complicated routines required.
This Works was founded in the UK and has since expanded globally. The brand sells through its own website, Amazon, and Sephora Canada. The Deep Sleep Pillow Spray is consistently rated the brand’s best-selling product and has earned that status through repeat buyers, not first-time novelty purchases.
What Ingredients Are in This Works Deep Sleep Pillow Spray?
This Works Deep Sleep Pillow Spray relies on a three-oil ‘Superblend’: Lavandula Angustifolia (lavender) oil, Vetivera Zizanoides (vetiver) oil, and Ormenis Multicaulis (wild chamomile) flower extract. The brand calls this a ‘clean, expertly blended system of naturally derived, scientifically proven ingredients at therapeutic levels.’
Lavender oil is the lead active. It carries well-documented calming properties, and linalool, one of its key compounds, is directly linked to reduced anxiety and faster sleep onset in multiple human studies. Bottom line: lavender here isn’t decoration. It’s doing real work.
Vetiver, sometimes called the ‘oil of tranquility,’ is the grounding element. The oil targets mental stress and racing thoughts. Ho Wood and Patchouli round out the aromatic base alongside the core trio, adding depth to the scent profile.
The full ingredient list also contains Aqua (water), Polysorbate 20 (emulsifier), Parfum, Diazolidinyl Urea, and Iodopropynyl Butylcarbamate as preservatives. The preservatives appear at concentrations well within industry safety limits.
Core Superblend Ingredients:
- Lavandula Angustifolia (Lavender) Oil
- Vetivera Zizanoides (Vetiver) Oil
- Ormenis Multicaulis (Wild Chamomile) Flower Extract
- Cinnamomum Camphora (Ho Wood) Oil
- Pogostemon Cablin (Patchouli) Oil
Is This Works Deep Sleep Pillow Spray Vegan and Cruelty-Free?
Yes. This Works Deep Sleep Pillow Spray is certified both vegan and cruelty-free, confirmed on all product listings and the brand’s official packaging. No animal-derived ingredients appear in the formula, and the brand does not conduct animal testing. For buyers who care about ethical sourcing, that’s a clear pass.
The packaging is largely recyclable. The bottle, cap, carton, inserts, and liner can all go in recycling. The spray pump is the one component not currently recyclable, per the brand’s own FAQ. Worth knowing: the brand is transparent about this limitation rather than claiming full recyclability.
The formula is also suitable during pregnancy and for children aged 3 and over under adult supervision. These are meaningful safety distinctions that separate it from many competing sleep sprays that carry no such guidance.
How Does This Works Deep Sleep Pillow Spray Work?
This Works Deep Sleep Pillow Spray works through inhalation of essential oils that trigger a calming response in the nervous system via the olfactory pathway. Here’s what that means: scent molecules reach the limbic system, the brain region governing emotion and stress. Lavender and vetiver activate this pathway to reduce arousal before sleep.
The brand conducted four independent studies on over 600 participants. One placebo-controlled trial tested 200 subjects with mild sleep anxiety. Users of the spray fell asleep faster, slept deeper, felt less anxious before bed, and reported lower fatigue the next morning versus the placebo group.
The Superblend formula delivers ingredients at what the brand calls ‘therapeutic levels,’ meaning concentrations high enough to produce a measurable effect. In plain English: this isn’t the same as a generic linen spray that uses a drop of lavender in a water bottle. The concentration matters.
How Do You Use This Works Deep Sleep Pillow Spray?
Using This Works Deep Sleep Pillow Spray requires just a few spritzes of fine mist directly onto the pillow or bedding before getting into bed. The brand recommends applying at bedtime, letting the scent settle into the fabric for a few moments before lying down. That’s it. No measuring, no mixing, no timers.
The spray can be used alongside the This Works Sleep Plus Pillow Spray for a layered approach. Deep Sleep helps users fall asleep faster. Sleep Plus is motion-activated and releases scent over eight hours to help users stay asleep longer. The two products are designed to complement each other.
Users with scent sensitivity can start with a single spray and adjust upward based on comfort. The formula comes ready to use. No diluting is required.
What Are the Benefits of This Works Deep Sleep Pillow Spray?
This Works Deep Sleep Pillow Spray delivers four clinically demonstrated sleep improvements: faster sleep onset, deeper sleep quality, reduced pre-sleep anxiety, and greater morning energy. These outcomes come from four independent studies on over 600 participants, including a 200-person placebo-controlled trial.
The 2014 study results are the brand’s most-cited benchmark. In that study, 97% of users reported sleeping better than normal. A separate metric showed 98% woke feeling more refreshed. And here’s the best part: 100% of participants said they’d recommend the product to a friend. That’s a rare consensus.
Beyond sleep itself, the product addresses pre-bed anxiety directly. Vetiver and chamomile target mental restlessness that keeps many people from settling. The spray addresses both the physical and psychological barriers to sleep onset in one formula.
Does This Works Deep Sleep Pillow Spray Help You Fall Asleep Faster?
Yes. This Works Deep Sleep Pillow Spray helped 89% of users fall asleep faster than normal in independent panel testing against a placebo. The placebo-controlled study used 200 male and female participants classified as having mild sleep anxiety, the demographic most likely to benefit from the product.
Lavender oil drives much of this benefit. Linalool, the primary compound in lavender, has been shown in peer-reviewed research to reduce sleep latency. The Deep Sleep formula delivers lavender at therapeutic concentration. Does this matter? Yes, because most cheaper sprays use diluted or low-grade lavender that doesn’t reach effective levels.
Anecdotal reports from Amazon reviewers reinforce the clinical data. One UK-based reviewer called the effect ‘like magic,’ reporting consistent improvement across six weeks after years of failed sleep aids. Across 22,765 reviews, that pattern suggests reliable efficacy rather than a one-off placebo response.
Does This Works Deep Sleep Pillow Spray Reduce Sleep Anxiety?
Yes. This Works Deep Sleep Pillow Spray reduced pre-sleep anxiety and morning fatigue in the brand’s 200-person placebo-controlled clinical study. Participants using the spray reported feeling less anxious before sleep and less tired throughout the following day compared to the placebo group. The effect extended beyond the night itself.
Vetiver oil is the primary anxiety driver in the formula. Known as the ‘oil of tranquility,’ vetiver grounds the mind and quiets racing thoughts that prevent sleep onset. Think of it this way: lavender calms the body, vetiver calms the mind. The two oils work as a pair.
Wild chamomile contributes a secondary calming layer. Ormenis Multicaulis differs slightly from the more common German or Roman chamomile but shares the same broadly sedative aromatic profile. Together, vetiver and chamomile address the psychological side of sleeplessness that lavender alone may not fully cover.
What Do This Works Deep Sleep Pillow Spray Reviews Say?
This Works Deep Sleep Pillow Spray holds a 4.3 out of 5 star rating on Amazon from 22,765 verified purchasers, ranking #3 in the Aromatherapy Mists and Hydrosols category. On the brand’s own site, the product holds a 4.5 out of 5 from 2,328 reviews. The good news? Both scores reflect genuine repeat-buyer satisfaction, not first-order enthusiasm.
The volume of positive reviews is striking. Users frequently describe dramatic sleep improvement after years of struggling with insomnia or light sleep. Repeat purchasers are common. Many reviewers report using the product continuously for months or years, which is the clearest possible signal that it delivers consistent results.
The spray also attracts strong loyalty in travel contexts. The 5ml miniature size sells well specifically because regular users want their established sleep routine in hotels. That kind of habit formation doesn’t happen with products that only work occasionally.
What Are the Most Common Complaints About This Works Pillow Spray?
The most common complaint about This Works Deep Sleep Pillow Spray is that the scent fades faster than users expect, sometimes dissipating before the night ends. Reviewers who struggle with staying asleep find the fragrance less effective for their needs than for initially falling asleep. For that use case, Sleep Plus is a more suitable option.
Price is the second recurring criticism. At $33 (USD) for 75ml (2.5 fl oz), the spray costs more than generic aromatherapy alternatives. Most reviewers who raise this objection qualify it immediately by noting that a single spray per pillow means the bottle lasts weeks to months. The per-night cost is low once the math runs.
Common Complaints:
- Scent fades too quickly for light sleepers who wake mid-night
- Price higher than unbranded pillow sprays
- Concentration too mild for severe insomnia cases
- Strong initial scent can feel overpowering for sensitive noses
Who Should Avoid This Works Deep Sleep Pillow Spray?
People with fragrance allergies or sensitivities should exercise caution with This Works Deep Sleep Pillow Spray due to known allergens: Linalool, Geraniol, and Limonene in the formula. These compounds appear on the EU fragrance allergen disclosure list and can trigger contact dermatitis in sensitive individuals. The label discloses all three.
The product is not recommended for direct application to pet bedding. The brand’s FAQ states that while incidental contact should not be concerning, direct spraying onto pet sleeping areas is not advised, as the formula has not been vet-assessed for animal safety.
Children under 3 years old should not use the product. For children aged 3 and above, adult supervision is required. Those with existing respiratory conditions like asthma may find concentrated essential oil mists irritating. A doctor’s input is worth seeking before use in those cases.
This Works Deep Sleep Pillow Spray vs Competitors: How Does It Compare?
This Works Deep Sleep Pillow Spray stands out through clinical testing, high review volume, and a tiered product line addressing different sleep difficulty levels. Most competing pillow sprays lack independent clinical data and rely on anecdotal marketing. The clinical proof here is real, not a vague ‘proven effective’ badge.
The closest comparisons come from within the This Works range itself. The brand offers three sleep sprays: Deep Sleep, Sleep Plus, and Sleep Power Nap. Each serves a distinct use case. Buyers choosing between them need to understand the concentration and mechanism differences before selecting the right one.
This Works Sleep Spray Comparison:
| Product | Price (USD) | Size | Best For |
|---|---|---|---|
| Deep Sleep Pillow Spray | $33 | 75ml (2.5 fl oz) | Falling asleep faster |
| Sleep Plus Pillow Spray | $48 | 75ml (2.5 fl oz) | Staying asleep, restless sleepers |
| Sleep Power Nap Spray | $50 | 50ml (1.7 fl oz) | Daytime naps, energy boost |
Is This Works Better Than Sleep Plus Pillow Spray?
This Works Deep Sleep Pillow Spray is better suited for users who struggle to fall asleep, while Sleep Plus suits those who wake frequently throughout the night. Sleep Plus contains three times the concentration of Deep Sleep and uses motion-activated technology that releases scent over eight hours. Different tools for different problems.
The price difference is $15 (USD) per bottle at the same 75ml (2.5 fl oz) size. Deep Sleep at $33 is the entry point to the range. Sleep Plus at $48 delivers more intense aromatherapy for more serious sleep disruption. Both can be used at the same time, which the brand explicitly supports.
For most users with mild to moderate sleep difficulty, Deep Sleep is the logical starting point. The upgrade to Sleep Plus makes sense only when the original spray improves sleep onset but users still report frequent waking throughout the night.
Is This Works Deep Sleep Pillow Spray Safe?
Yes. This Works Deep Sleep Pillow Spray has been tested in four independent user studies on over 600 participants and is certified cruelty-free and vegan with no animal-derived ingredients. The formula is designed for external use only, applied to bedding rather than skin, which reduces direct absorption risk considerably.
The preservatives used, Diazolidinyl Urea and Iodopropynyl Butylcarbamate (IPBC), are both approved cosmetic preservatives. IPBC at 0.1% has an extremely low skin irritation rate: approximately 0.1% of 4,883 participants at 24 hours, rising to 0.5% at 48 hours. Those figures classify it as mild and safe for most users.
The formula contains Linalool, Geraniol, and Limonene as fragrance components, all disclosed under EU allergen regulations. Sensitive individuals should cross-reference these against known personal sensitivities before purchasing. That’s standard due diligence for any fragrance product.
Are There Any Side Effects of This Works Pillow Spray?
The most documented side effect of This Works Deep Sleep Pillow Spray is allergic skin reaction, particularly in individuals sensitive to Linalool, Geraniol, or Limonene. These allergens are disclosed on the label. Users who suspect fragrance sensitivity can test a small amount on inconspicuous fabric before committing to regular use.
Eye contact should be avoided. The label instructs washing with plenty of soap and water if the product reaches skin directly. No serious adverse events appear consistently across the 22,765-review Amazon dataset, which suggests the rate of problematic reactions is low in the general population.
Here’s the important distinction: the spray is not a therapeutic drug. It carries no pharmacological side effect profile. Aromatherapy products at this concentration do not produce systemic effects equivalent to oral sedatives. Users who experience persistent skin irritation or rash should seek medical advice.
How Much Does This Works Deep Sleep Pillow Spray Cost?
This Works Deep Sleep Pillow Spray retails for $33 (USD) for the standard 75ml (2.5 fl oz) size on the brand’s official website, with free shipping on all orders over $30. A 30-day money-back guarantee backs every purchase made directly through thisworks.com. That’s a meaningful risk reduction for first-time buyers.
Multiple sizes are available. The 5ml miniature is the travel option. The 400ml (13.5 fl oz) refill bottle retails at $56, reduced from the regular $70 (saving $14 USD), and represents the most cost-effective option for committed daily users.
Available Sizes and Prices (USD):
| Size | Price | Best For |
|---|---|---|
| 5ml (0.17 fl oz) | Travel size price | Travel and trial |
| 10ml (0.34 fl oz) | Sample size price | First-time buyers |
| 75ml (2.5 fl oz) | $33 | Standard home use |
| 250ml (8.4 fl oz) | Larger format | Heavy daily users |
| 400ml refill (13.5 fl oz) | $56 (was $70) | Best value, repeat buyers |
Is This Works Deep Sleep Pillow Spray Worth the Price?
Yes. This Works Deep Sleep Pillow Spray delivers measurable sleep improvement backed by four clinical studies, which separates it clearly from lower-priced sprays that offer no clinical validation. At $33 for 75ml, the product costs more upfront than unbranded alternatives. But the math changes when daily cost is calculated.
One or two sprays per pillow each night means a single 75ml bottle lasts roughly four to six weeks for one user. The daily cost works out to approximately $0.75 to $1.10 (USD) per night. That figure compares favorably to melatonin supplements or herbal sleep capsules at similar or higher price points with far less clinical backing.
The 100% recommendation rate from clinical study participants and the 30-day money-back guarantee on the official website both reduce purchase risk significantly. Users who find the product ineffective have a clear return path available.
Where Can You Buy This Works Deep Sleep Pillow Spray?

Is This Works Deep Sleep Pillow Spray Worth It?
Yes. This Works Deep Sleep Pillow Spray is one of the most clinically validated sleep sprays available, backed by four independent studies on over 600 participants. The combination of clinical proof, 22,765 Amazon reviews, and a 30-day money-back guarantee makes the purchase decision straightforward for most buyers.
The product excels for users with mild to moderate sleep difficulty, particularly those who struggle with pre-sleep anxiety or slow sleep onset. It’s not a replacement for medical treatment of chronic insomnia. Users with severe, ongoing sleep disorders should treat this as a complement to professional guidance, not a substitute.
For daily use, the 400ml refill at $56 (USD) delivers the best long-term value. First-time buyers are best served by the 75ml at $33 through thisworks.com, where the money-back guarantee applies. The product has earned its bestseller status through consistent, clinically supported performance and a repeat-buyer base that doesn’t lie.
