The Back on Track Pet Igloo, often sold under the name Rajah, is a compact, enclosed bed designed primarily for small dogs and cats. It combines a den-like igloo shape with the brand’s Welltex technology, which reflects the animal’s own body heat as far-infrared energy. Pet owners searching for this product typically want clear details on how it works, whether it suits their animal’s needs, how to care for it, and what sets it apart from ordinary pet beds.
This article covers the product’s design, the technology behind it, practical features, potential benefits, limitations, and everyday use so you can decide if it fits your pet.
What Is the Back on Track Pet Igloo?
Back on Track is a Swedish company known for textiles that incorporate ceramic or mineral particles into fabric. The Pet Igloo (Rajah) is one of their products aimed at companion animals. It forms a soft, foldable cave-style bed that gives the animal a secure, enclosed space while the inner lining works with the pet’s body heat.
The design prioritizes a sense of safety and the ability to observe surroundings from a protected spot. It is marketed for both dogs and cats, especially smaller ones, and is intended for indoor use or travel. Dimensions commonly listed for the product are around 37 cm long by 37 cm wide by 40 cm high, making it suitable for pets that fit comfortably inside a compact enclosure.
Materials typically include polyester outer fabric, soft filling (polypropylene and polyurethane components appear in specifications), and a Welltex-lined interior. Artificial-leather accents add a finished look in available colors such as gray or brown.
How Welltex Technology Works
Welltex is the core differentiator. Ceramic or natural mineral particles are melted into the polyester fibers during manufacturing. These particles absorb heat generated by the animal’s body and re-emit it as far-infrared radiation (FIR).
According to the manufacturer, this reflected energy can support increased blood circulation in the areas in contact with the fabric. Improved circulation is associated with greater flexibility in muscles, tendons, and joints, and may help ease stiffness or discomfort linked to conditions such as osteoarthritis or general joint issues. The effect is passive—it relies entirely on the pet’s own body heat and does not involve electricity, batteries, or external heat sources.
The minerals are permanently incorporated into the fibers, so the reflective property is not washed out with normal care. Results vary by individual animal; some pets show noticeable relaxation or reduced stiffness after regular use, while others respond more subtly. Gradual introduction is often recommended so the animal can adjust.
This is not a medical treatment or cure. It is a supportive textile approach based on the principles of far-infrared reflection. Consult a veterinarian for diagnosed joint or muscle conditions.
Key Features of the Pet Igloo
- Enclosed igloo shape – Creates a cave-like retreat that many dogs and cats find comforting. The opening allows the pet to monitor the room while feeling protected.
- Welltex-lined interior – Provides the far-infrared effect described above across the contact surfaces.
- Soft, formable construction – The bed can be folded or packed relatively flat for storage or travel, then reshaped for use.
- Removable outer cover – A zipper at the bottom lets you remove the outer fabric for washing.
- Non-slip base – Helps keep the bed in place even when the pet moves around or plays nearby.
- Machine-washable – Designed for practical cleaning. Typical care instructions call for washing at 40°C on a gentle cycle with regular detergent, no bleach or fabric softener, no tumble drying, and air drying.
- Stylish details – Artificial-leather accents and a heathered or solid fabric exterior give it a more finished appearance than basic pet beds.
These features make it more than a simple cushion; the combination of enclosure, thermal reflection, and portability addresses both comfort and mobility support.

Potential Benefits and Who It Suits Best
Pets that seek enclosed spaces often settle quickly into the igloo. The far-infrared effect may be especially relevant for older animals, those with mild joint stiffness, or pets recovering from activity. Small dogs and cats that enjoy burrowing or denning behavior tend to use it readily.
Practical advantages include easy transport for travel or visits, a stable footprint thanks to the non-slip base, and straightforward cleaning. Because the technology works with the pet’s own heat, there is no risk of overheating from an external power source.
It is less ideal for large dogs or animals that prefer open, sprawling beds. Very active chewers may damage the fabric or zipper. Pets that overheat easily should be monitored, although the design is not a heated bed in the conventional sense.
Important Considerations and Limitations
Sizing is critical. Measure your pet and compare against the roughly 37 × 37 × 40 cm dimensions. A pet that is too large will not fit comfortably or may not achieve good contact with the Welltex lining.
The product is not a substitute for veterinary care, joint supplements, weight management, or appropriate exercise. Effects on circulation and comfort are supportive rather than dramatic for every animal. Individual response differs.
Availability and exact pricing vary by region and retailer; listings have appeared in European and North American markets under Back on Track or authorized sellers. Always verify current product specifications, as designs or materials can be updated.
Common practical notes: introduce the bed gradually if your pet is wary of new objects; place it in a quiet, draft-free spot initially; and keep it clean so the lining remains effective and inviting.
Care and Maintenance Tips
Follow the care label closely. Machine wash the removable cover at 40°C on gentle with ordinary detergent. Avoid bleach, fabric softener, dry cleaning, ironing, and tumble drying. Air dry completely before reassembly. Spot-clean the inner components as needed and ensure the bed is fully dry to prevent odor or mildew.
Regular cleaning maintains hygiene and allows the Welltex fibers to perform as intended. Store the folded bed in a dry place when not in use.
Frequently Asked Questions
Is the Back on Track Pet Igloo suitable for cats as well as dogs?
Yes. The brand and retailers present it for both small dogs and cats. Many cats appreciate the enclosed shape.
Does it require electricity or batteries?
No. It works solely by reflecting the pet’s own body heat through the mineral-infused fabric.
How do I know if the size is right?
Check the product dimensions (commonly around 37 × 37 × 40 cm) against your pet’s length and preferred sleeping posture. The animal should be able to enter, turn around, and rest without crowding.
Can it help with arthritis or joint stiffness?
The manufacturer states that the increased circulation from far-infrared reflection may support animals with osteoarthritis, stiffness, inflammation, or joint concerns. Results are individual and supportive only. Speak with a veterinarian for medical advice.
Is it easy to travel with?
Yes. The soft, formable construction allows folding and packing, which is useful for trips or temporary moves.
How should I introduce it to a cautious pet?
Place it in a familiar area with a favorite blanket or toy inside. Allow the pet to investigate at its own pace rather than forcing entry.

Final Thoughts
The Back on Track Pet Igloo offers a practical combination of secure enclosed design and passive far-infrared support through Welltex technology. It is best suited to small dogs and cats that enjoy den-like spaces and may benefit from gentle circulatory support during rest. Clear sizing, straightforward care, and the ability to fold it for travel add everyday usefulness.
If your pet fits the size range and you are looking for more than a basic cushion, this product provides a focused option grounded in the brand’s established textile approach. Always pair any supportive bed with good overall care, appropriate veterinary guidance when needed, and observation of your individual animal’s response.
