From the people using it.
What changed, in their words.
The first week I mostly just lay there wondering if I was doing it right. By week three the session had become the line between work brain and home brain. I come out properly calm, not just tired, a different feeling. My shoulders have stopped living next to my ears.
Three kids, a full-time job, and a body that has not felt like mine in years. I spent six weeks telling myself I could not justify it. The 40 minutes with the door shut is now the one thing in my week that is only mine, and nobody is allowed to touch it.
January is usually when I go under. This year I did the blanket most mornings instead, 30 minutes before the house woke up. I cannot tell you how much is the heat and how much is having an anchor, but it is the best I have come through a winter in five years.
Four years of waking three or four times a night. The first fortnight nothing much changed and I nearly wrote it off. Around week three I started falling asleep within twenty minutes of bed, and four months on I wake once at most. I feel rested for the first time in years.
I track my sleep, so this is not a vibe. Deep sleep climbed within the first month of evening sessions and has held for six months since. The session itself is forty unglamorous minutes of sweating to a podcast. The graph afterwards is the part I care about.
At 52 my nights had become a mess and I bought this half out of desperation. The early sessions were honestly just pleasant, nothing more. Six weeks in, my sleep is steadier and I am down to one or two bad nights a week instead of five. Not fixed, but changed enough to matter.
I am 62 and my knees and hands set like concrete overnight. A neighbour let me try hers and I bought my own that week. The stiffness still arrives, I will not pretend otherwise, but on blanket mornings I am moving freely around the kitchen in fifteen minutes instead of forty-five.
Four years of a bad back, physio, chiro, the lot. The blanket has not fixed it, nothing has. But six months of evening sessions and it has become the single most useful thing I do for managing it day to day. Mornings after a session I move noticeably easier. It earns its place.
Training for a hundred-miler, so recovery is the whole game. The first couple of weeks I treated it as a nice warm lie-down. Then I noticed the day after long runs felt different, legs looser, sleep deeper. It is now scheduled into the plan the same as the runs are.
I was paying 85 pounds a month for a spa membership I used mainly for the sauna, maybe twice a month when life allowed. Cancelled it. I am in this blanket more evenings than I ever made it to the spa, and the blanket paid for itself before the membership renewal would have landed.
I got hooked on the infrared sauna at my gym, but getting there at six in the morning was never going to last. This is the same feeling at home, maybe better because I am lying flat. First week I underestimated the sweat and overdressed. Lesson learned, towel down, drenched, happy.
I was seeing an osteopath weekly at 60 pounds a visit, mostly for stress tension rather than anything structural. Five months of regular sessions in this and I have stretched the visits to every six weeks. The osteopath was gracious about it. My bank account was more than gracious.
Clinician notes
What clinicians tell us.
Clinician note
In rehab work the gap is rarely knowledge, it is the wind-down people never actually do. Passive heat is one of the few recovery inputs my patients keep, because lying still in warmth asks nothing of them. I see it ease perceived muscle tension and help the evening shift into rest. It supports recovery, it does not treat injury, and anyone with a heart condition, a pacemaker, or a pregnancy needs their own doctor's clearance before regular heat sessions.

Clinician note
Most of my poor sleepers do not have a sleep problem at nine pm, they have a switching-off problem. A warm, screen-free half hour in the early evening gives the body a clear signal that the day is ending. I am careful with claims here. Heat rituals support wind-down for many people, they are not a treatment for insomnia, and anyone on medication or with a medical condition should clear regular sauna use with their own doctor first.

Precision heat control
The digital controller offers adjustable temperature from 30°C to 70°C and timer settings from 20 to 60 minutes. Start at 45–50°C for your first sessions, then dial up as your body acclimates. Auto-shutoff engages when your session ends.
Stay connected or fully cocooned
Dual arm openings with closable flaps let you choose your experience. Keep arms out to hold water, use your phone, or read. Seal them closed for full-body immersion. The choice is yours every session.
Designed for solo use
Both zippers operate from inside the blanket. Zip yourself in without assistance, adjust positioning mid-session, exit when ready. No awkward contortions, no need for a second person. Complete autonomy from setup to finish.
Hygiene engineered in
The interior lining is treated with antimicrobial technology that prevents bacterial growth and odour between sessions. A towel insert and a quick post-session wipe keep it fresh, session after session.
No hot spots, no cold zones
Twenty metres of silicone heating wire run the full interior surface in a dense, even layout, delivering consistent far-infrared heat from shoulders to feet. Unlike cheaper blankets with sparse heating elements, every inch of your body receives the same therapeutic intensity.
Before you add to cart
Is this the right blanket for you?
Where are you right now?
The science
Why infrared heat works.
Far-infrared has been studied in clinical and athletic recovery settings for decades. The blanket delivers it at 5 to 15 microns across the whole body, warming tissue directly rather than the air around you.

Far-infrared at 5 to 15 microns penetrates into muscle and joint tissue rather than resting on the skin. A heating pad warms the surface. Far-infrared warms the layer where chronic tension actually sits, which is why users describe coming out looser, not just warmer.
The downshift your body recognises.
Sustained, even warmth cues the parasympathetic state, the rest-and-digest mode where heart rate eases and muscles release. The sauna-bathing literature consistently reports relaxation and wellbeing effects, and users describe the session as the line between work brain and home brain.
A proper sweat, on purpose.
Sweating usually starts around minute 10 to 15 and peaks between 20 and 35. Because the heating wire covers the whole interior edge to edge, the sweat is full-body and even rather than patchy, the gym-level sweat without the gym, ending exactly when your timer says.
An evening ritual that supports sleep.
Warming the body in the hour or two before bed is one of the better-studied sleep supports. A pooled analysis of 13 studies found people fell asleep faster and rated their sleep higher after pre-bed passive heating, and blanket users describe floating to bed after an evening session.
A systematic review of 40 clinical studies links regular sauna bathing, including infrared formats, with improved wellbeing.

Materials and safety
The build, layer by layer.
Waterproof Oxford fabric shell
A dense woven shell that wipes clean and stays matte. The vinyl sheen and chemical smell that haunt budget-blanket reviews come from PVC shells, and this is not one.
Insulated padding that holds heat where you are
The core keeps warmth against the body instead of leaking it into the room, so the controller is not fighting to hold temperature. Thin foil-style blankets run loud, uneven, and lukewarm. This one does not.
20 metres of silicone heating wire, edge-to-edge coverage
Twenty metres of silicone-sheathed heating wire run the full interior in a dense, even layout, delivering far infrared in the 5 to 15 micron band across the whole surface. The cold-feet, hot-hips complaint in cheap blankets is a sparse-layout problem, and edge-to-edge coverage removes it.
Live temperature display with a 20 to 60 minute auto-shutoff
The controller shows the actual blanket temperature, holds it where you set it between 30 and 70C, and the timer cuts power on its own, every session. The flimsy dial controller that drifts hot is the failure mode this replaces.
Temperature sensing with an independent thermal fuse
A sensor reads the blanket's heat continuously, and a separate thermal fuse sits behind it, cutting power on its own if anything ever runs outside its range. It answers the question every careful buyer asks of an electric blanket they lie inside.
The Clinic Experience, Unlocked.
For years, the depth of far-infrared heat was locked behind expensive, appointment-only clinics.
Advancements in technology and materials have changed that.
We engineered Soln devices to deliver the same deep-penetrating infrared wavelengths used in professional clinic panels, now in a flexible home format.
Before
After
One clinic session per week for one year vs. one device at home, indefinitely.
Temperature settings
The controller offers precise temperature control from 30°C to 70°C. If you're new to infrared therapy, start at 45–50°C for your first three sessions. Once acclimated, most users settle at 55–65°C for deep sweat. For the deepest sessions, dial up to the 70°C maximum.
What to wear
Wear lightweight, breathable clothing (cotton T-shirt and shorts) or use the blanket nude with a towel barrier. Avoid synthetic fabrics, they trap heat uncomfortably and don't breathe. Many users prefer minimal clothing to maximize skin contact with infrared heat.
Preheating
Winter: Preheat the blanket for 10–15 minutes before getting in. The fabric will feel warm to touch and sessions will be more comfortable from the start.
Summer: 2–3 minutes is enough. The blanket heats quickly and you'll reach full sweat faster in warmer ambient temperatures.
Using a towel insert
Place a large bath towel inside the blanket before zipping in. This absorbs sweat and creates a hygiene barrier between your skin and the blanket's interior lining. After each session, remove the towel and launder it. This eliminates the need to clean the blanket interior after every use.
Timer and duration
Use the built-in timer on the controller. First-time users: 20–25 minutes. Regular users: 30–40 minutes. The blanket will auto-shut-off at your set time for safety. You'll begin sweating around minute 10–15. Peak sweat happens between minutes 20–35.
Arm positioning
The blanket has built-in arm openings. Keep arms inside for full-body heat or slide them out if you want to read, use your phone, or hold a water bottle. Both zippers operate from the inside, you control entry and exit entirely.
Immediate care
Unzip and step out slowly, giving your body a minute to adjust. Hydrate immediately (we recommend 300–500ml of water with electrolytes). Shower if desired, though many users prefer to let the skin absorb the post-session minerals for 10–15 minutes.
Cleaning and maintenance
Wipe down the interior lining with a damp cloth and mild soap after each use (takes 60 seconds). For deeper cleaning, use an antimicrobial spray designed for gym equipment once per week. The exterior can be wiped with a dry cloth. Never submerge the blanket or put it in a washing machine, the heating elements are integrated into the fabric.
Storage
Fold the blanket in half lengthwise, then roll from one end. Store flat or upright in a closet. It takes up roughly the same space as a yoga mat. Avoid storing in damp environments (basements, bathrooms) to prevent any moisture buildup in the fabric.
Frequent Questions
How long until I see results?
Most users notice they sleep better and their muscles feel looser after their first session. With consistent use (3–4 sessions per week), the cumulative effects become more pronounced over 2–3 weeks: tension releases faster, recovery feels deeper. The timeline varies based on how often you use it and what you're looking for. Some notice changes immediately. Others feel the shift building over the first month.
Does it actually work, or is this just marketing hype?
Far-infrared at 5–15 microns isn't new technology, it's been researched in clinical and athletic recovery settings for decades. Studies document its effects on blood flow, heat penetration depth, and stress biomarkers. This is the same wavelength spectrum professionals use in recovery clinics. Over 12,000 customers have made this part of their daily routine for muscle and stress relief, sleep quality, and deep sweat sessions.
What if it doesn't work for me?
Give it three to four sessions a week for three weeks; that is where the sleep and tension changes show for most owners. Unused blankets can be returned within 60 days of delivery for a full refund, and from first session onward you are covered by the 24-month manufacturer warranty on materials and heating elements. We handle all warranty claims directly, no third-party runaround.
How do I clean it? Will it get mouldy from sweat?
Use a towel insert during every session to absorb sweat. After each use, wipe the interior lining with a damp cloth (takes 60 seconds). The antimicrobial lining prevents bacterial growth and odour, and a weekly once-over with gym-equipment spray handles the deep clean. That is the whole routine. The lining stays fresh.
Are there any safety rules I should know?
Yes, treat this like any heat therapy device. Don't fall asleep in it. Don't use it after drinking alcohol. Stick to 40–60 minute sessions max. If you're pregnant, have a pacemaker, or have a medical condition your doctor is managing, get your doctor's clearance first. Avoid using it over open cuts or wounds, and keep it away from water. It's designed for intentional, timed sessions, not all-night use.

Our name
Two origins, one purpose
Solen, the Swedish word for sun.
SOLN, Science Of Light and Nature.
Our name holds both: ancient recognition of light's restorative properties and modern understanding of how wavelengths interact with the body. Soln makes wellness technology that bridges the two. Clinical-grade wavelengths, designed for home.
What you'll feel
Built for the body that carries everything
For years, professional-grade wellness technology meant clinical environments and the compromises of shared spaces. Soln exists to collapse that distance, bringing the depth of professional-grade sessions into spaces that feel like your sanctuary. We believe you should not have to choose between precision and comfort.
What's measured
The science behind
The sun delivers infrared and red light wavelengths naturally. Your body recognizes them. Infrared penetrates tissue, you feel it as deep warmth. Red light reaches structures beneath the skin. PEMF creates electromagnetic fields your cells can detect. These wavelengths have been studied in clinical and athletic settings for decades. Soln devices deliver them with precision, calibrated to the ranges researchers have documented.
