In one sentence: all our unsinkable canoes come with a factory-standard backrest included in the price, with no extras or "upgrades". The backrest is the canoe's factory standard: it is not adjustable, but it is there on every canoe in the fleet. And it makes a real difference between reaching Fríes with a rested back or a stiff one.
When a family calls for the first time to book the Sella descent, there are three questions that always come up: how long it takes, what to wear and whether the children can do it. Almost nobody asks about the canoe backrest. And yet it is the part that changes the experience the most once you have been paddling for two hours.
At Aventura en el Sella we have spent more than 25 years taking families down the river, and there is one detail we repeat in every briefing: all our canoes come with a factory-standard backrest, at no extra cost, always. It is not an upgrade. It is not a "Premium" feature. It is the standard equipment on any canoe that leaves our base in Arriondas. In this guide we explain exactly what that backrest is, why it matters and what happens on the river with a canoe with no backrest. Without inflating differences: with facts.
What the backrest is and why almost nobody gives it any importance
The backrest of a descent canoe is a padded piece anchored to the seat that supports the lower back while you paddle. It is not an armchair. It is a piece designed so your back rests in a natural position, without having to keep your core muscles contracted the whole time.
Visually, it is two parts:
- The structure: rigid technical plastic, integrated into the seat at the factory. Neither height nor tilt is adjustable: it comes sized as standard by the manufacturer to suit most adult and child sizes.
- The padding: closed-cell foam. It does not get wet "inside", it air-dries on its own and holds its shape all season without losing form.
Why is it given so little importance? Because from the bank, in the photos on company websites, all the canoes look alike. You will see a yellow, orange or blue canoe, two paddles, a life jacket, and you will assume it is comfortable. But the difference between a canoe with a backrest and a canoe with a moulded seat and no backrest is something you only feel once you have been paddling for an hour. And by then it is too late to switch.
The natural posture of an adult seated for more than 30 minutes without a backrest creates tension in the lower back (L4-L5). In an activity like the Sella, where the body is seated for between 2 and 5 hours, that tension builds up. If you come with a pre-existing back problem, you will notice it straight away.
Mini, Complete and the tally of the hours in the canoe
The Sella descent has two routes depending on the company. With us they are:
- Mini (7 km · Arriondas → Toraño): between 2 and 3 hours seated in the canoe.
- Complete (14.5 km · Arriondas → Fríes): between 4 and 5 hours seated in the canoe.
Those hours are effective paddling or floating time, not standing up stretching. Except for the stops at the riverside bars (we recommend doing at least one), the body stays in the same position. If you want the more precise calculation per person, we work it out in how long the Sella descent takes.
Let's do the maths with the back in mind:
- Mini (2-3 h) without a backrest: moderate lower back tension, aches the next day. With a backrest: natural posture, normal recovery.
- Complete (4-5 h) without a backrest: noticeable built-up tension, a "loaded" back for 24-48 h. With a backrest: natural posture, normal recovery.
It is not a commercial invention: it is what we hear in the calls the Monday after the descent. Anyone who comes with a pre-existing lower back problem notices it two or three times more. If you are especially worried about getting tired, we break it down for you in is the Sella descent tiring?.
Do all the Sella companies include a backrest? The unvarnished truth
Here we have to be honest. Not all the companies operating on the Sella include the backrest in the base price.
The real picture, after 25 years in the sector, is more or less this:
- Companies that always include a backrest (like us): the backrest comes with the canoe by default. It is the canoe model we have in our fleet. There is no extra ticket, no "Premium upgrade", nothing charged separately.
- Companies with a basic seat and no backrest + backrest as an extra: the standard canoe is a moulded plastic seat and, if you want a backrest, you pay for it separately (it usually costs between €3 and €5 per person).
- Companies with mixed canoes: part of the fleet has a backrest and part does not. You get whatever you get on the day you go.
Our real advantage: you always get the backrest included because it is the factory-standard equipment on every canoe in the fleet. It is not magic, it is a purchasing decision. When we renew canoes, we buy only models that come with a backrest as standard.
If you book with another company, we recommend you ask literally: "Does the canoe come with a backrest included in the price, or is it paid for separately?" Without that specific question, the answer can be an ambiguous yes.
How to sit to make the most of the backrest during the descent
The backrest comes from the factory and is not adjustable, so the adjustment is made by your posture, not by the piece. The good news: the manufacturer's sizing works for most adult and child sizes from 1.15 m. These are the practical tips we give in the briefing before boarding:
- Back fully supported. Sit right to the back of the seat, with your lower back pressed against the backrest. If you stay "leaning forward", the backrest is not doing its job.
- Relaxed shoulders. Don't hunch forward to reach the water. The paddle gets there on its own, the river carries you. If you feel tension in your shoulders, you are too tense.
- Feet supported. Keep your legs half-stretched with your feet resting against the canoe. That stabilises the hips and frees up the back.
- Switch your paddling hand from time to time. Alternating the side you paddle on spreads the effort and avoids always loading the same side.
- If you feel any discomfort, stop at any of the 6 riverside bars along the route (Riverland, El Oasis, El Prau, El Bosque, La Mediana or Toraño), get out, stretch a little and carry on. The kilometres go down, the good memories go up.
- If something breaks or stops working in the kit (a worn backrest, a faulty life jacket), we swap your canoe at no cost at the next point where we have a support vehicle.
It is not a complex protocol. It is the routine of every outing for more than two decades.
Practical benefits · why a straight back makes the difference
Having a backrest in the canoe is not a whim. It has four concrete benefits we are going to break down:
- Real lower back comfort, not the brochure kind. Anyone with a pre-existing back problem (mild hernia, occasional lower back pain, slight scoliosis) notices it from minute 20. The backrest lets you keep your natural lumbar curve without having to hold it up with your own muscles. We hear it in the reviews we get every Monday.
- Photos on the move with natural posture. If you are going to take photos of the descent (and you will: the scenery between Pozo del Arco and the Fríes straight is Natural Heritage), an upright posture looks better on camera. A canoe with no backrest ends up with your back hunched forward, shoulders dropped and belly sunken.
- Children better supported, fewer scares. For children from 5 years (our minimum, along with 1.15 m in height), the backrest is extra support. A tired child tends to drop the paddle because their body weighs forward. If the backrest holds them, they keep hold of the paddle longer and enjoy it more. More detail in the Sella descent with children.
- Fewer aches the next day. Without a backrest, the norm is 24-48 hours of lower back and upper back aches. With a backrest, the aches are concentrated in the shoulders and arms (which is what you have really worked), and the back recovers the next day.
Visual comparison · canoe with backrest vs without backrest
This is for anyone who wants to compare before booking. Real figures, no marketing:
- Back posture · With backrest: natural lumbar curve supported. Without backrest: back contracted, no support.
- Comfort 2-3 h (Mini) · With: good, no built-up tension. Without: acceptable for the first 60 min, then discomfort.
- Comfort 4-5 h (Complete) · With: good right to the end. Without: noticeable tension, especially the last hour.
- Minimum recommended age · With: 5 years (at 1.15 m). Without: 8-9 years (needs more developed muscles).
- People with previous lower back pain · With: suitable, ask first. Without: not advised.
- Posture for photos · With: upright, natural. Without: hunched forward.
- Aches the next day · With: shoulders and arms. Without: shoulders, arms, upper back and lower back.
- Price of the backrest on the Sella · With us: included in the base price (€35 adult / €25 up to age 12). Other companies: it usually costs €3-5 extra per person if they offer it as an upgrade.
Our price includes a canoe with a factory-standard backrest + paddle + life jacket + dry barrel + a dog life jacket if you bring a dog + the coach transfer. Full detail in 2026 prices.
Material, maintenance and what happens if it breaks
Three technical questions we get asked a lot:
- What is it made of? The structure is rigid technical plastic integrated into the seat at the factory. The padding is closed-cell foam, the same type of material as wetsuits. It does not absorb water, it does not stay soaked, it air-dries. If a splash gets in during the descent or you capsize (capsizing on the Sella is exceptional, but it happens), the backrest keeps working immediately.
- How is the fleet checked? A full inspection at the start of every season (March-April) + a weekly check during July and August, which are the busiest months. If a canoe has a worn backrest, it comes out of the circuit until it is repaired or replaced.
- And if I get a worn one? We swap your canoe at no cost. If you spot it before boarding, at the base. If you spot it on the river, at the next riverside bar with road access (Riverland or La Mediana). Same day, no argument.
We have been doing this since the last century. The equipment is our responsibility, not yours. If you are interested in the history of the river and how the fleet evolved, we tell it in the history of the Sella descent.
Who the backrest is especially recommended for
Having a backrest in the canoe is something we recommend to everyone (in fact, it is included without exception in our canoes), but there are profiles that should not go down the Sella without one under any circumstances:
- People with lower back pain, a mild disc hernia or scoliosis. If your back gives you grief day to day, without a backrest the descent becomes a problem. With a backrest, it is perfectly enjoyable. For more serious cases (active hernias, recent surgery), ask us before booking.
- People over 55-60. The lower back muscles lose elasticity with age. The backrest supports what the body no longer does. Also useful for pilgrims on the Camino del Norte who arrive with several stages behind them.
- Families with children aged 5-9. Minimum age in our canoes: 5 years and 1.15 m. The backrest stops the child tiring before time. We cover this in the descent with small children.
- Anyone coming to do the Complete (14.5 km). From hour 3 onwards, without a backrest, the descent becomes a struggle.
Important to remember: the Sella descent cannot be done during pregnancy (not even in the first trimester). Nor with active serious illnesses (cardiovascular, respiratory, epilepsy or others that can be aggravated by physical effort or immersion). And being able to swim is a mandatory requirement by law for all participants. We break it down in our terms and conditions.
If your profile is on this list and you are being offered a canoe with no backrest, insist or change company. It is not just our recommendation: it is prevention.
Booking the descent with the backrest included in the price
Booking with us is the direct way to make sure the backrest is included. No extras, no added charges, no disguised "Premium upgrades". Some rules we always apply:
- Booking ahead strongly recommended, especially in July, August and bank-holiday weekends. In May, June or September we usually have room on the same day, but it is worth confirming.
- Book via the website, WhatsApp, phone or email. You have the short form to book online with a real-time calendar.
- The river closes at 18:00 by order of the Confederación Hidrográfica del Cantábrico. For the Complete we recommend setting off before 11:00 (a comfortable day).
- Premium option (the same canoe with backrest + Premium extras): /en/premium-booking/, an open window from 10:30 to 12:30 without choosing an exact time.
- Pets: free, with a dog life jacket included while stocks last.
- Best time to come: we tell you in the best time for the Sella descent. If you are coming in a large group, have a look at the Sella descent for groups and stag and hen dos.
And if you want to know who is behind all this, we tell you in about us. In 25 years we have seen grandparents, tired pilgrims off the Camino and five-year-olds come down the Sella. The backrest is not the only reason they come back, but it is the first one they mention when they call on the Monday to thank us for how well they slept that night.
What you ask us most
- Is the backrest included in the price of the Sella descent?
Yes. All our canoes come with a factory-standard backrest, at no extra cost. The base price (€35 adult, €25 up to age 12, pets free) already includes a canoe with backrest, a paddle per person, a life jacket, a dry barrel and the return coach transfer. Here is the full detail of what each price includes.
- What material is the canoe backrest made of?
The backrest is the factory standard that comes with the canoe: a technical-plastic structure anchored to the seat, with closed-cell foam padding that does not absorb water. It is not adjustable — it comes already fitted and sized by the manufacturer. It is the same backrest on every canoe in our fleet, whether you are doing the Mini or the Complete.
- Does it improve posture for small children?
Yes. For children from 5 years (our minimum, along with 1.15 m in height), having a backrest gives extra support that stops them tiring before time and dropping the paddle out of discomfort. It also reduces the risk of knocking against the edge of the plastic when shifting position. We cover this in the Sella descent with small children.
- What happens if the backrest is worn out?
We swap your canoe at no cost: at the base before setting off, or at the next riverside bar with road access (Riverland or La Mediana) if you spot it on the river. We check the whole fleet at the start of the season and weekly during July and August.
- Does the backrest work for people with lower back problems?
Yes. We especially recommend it to people with lower back pain, a mild disc hernia or slight scoliosis. Having a backrest (vs not having one) supports the natural lumbar curve throughout the 2-5 hours the descent lasts, preventing tension from building up. If you have any doubts, call us or write to us by WhatsApp or email before booking so we can assess your case.
