Setup and Care
Setup: Place the adjustable base on a flat, stable surface and use a compatible mattress to ensure a perfect fit and optimal support.
Adaptation: The adjustment period varies from person to person but usually takes a few weeks to get used to all the different positions and features. Experiment with the settings to find the position that gives you the most comfort.
Care: Check the adjustment mechanisms regularly to ensure they are functioning properly. Clean the base with a soft, damp cloth to remove dust.

Frequently Asked Questions
What makes the Sophia 4 different from the Sophia 2?
The Sophia 4 adds three major features the Sophia 2 does not have: Trendelenburg and reverse Trendelenburg positioning (up to 16 degrees each), full height adjustment with a 30-inch range, and a built-in vibro-massage system. It also includes a wireless remote and has a lifetime structural warranty. If you want Trendelenburg tilt or height adjustment at home, choose the Sophia 4. Call us at 519-770-0001 to compare both models.
What is Trendelenburg positioning?
Trendelenburg is a named position where the bed tilts so the feet sit higher than the head. Reverse Trendelenburg tilts the opposite direction, so the head sits higher than the feet. The Sophia 4 offers both at up to 16 degrees. If you are managing a medical condition, ask your doctor which positions suit you.
Is the Sophia 4 good for home care and medical conditions?
The Sophia 4 has Trendelenburg and reverse Trendelenburg tilt up to 16 degrees, head elevation to 68 degrees, foot elevation to 9 inches and 4 inches of adjustable lumbar support. The 30-inch height adjustment makes it easier for caregivers to assist with transfers, and the 800 to 900 lb weight capacity handles bariatric needs. Always consult your doctor about specific medical positioning recommendations. Visit us at 441 1/2 West St, Brantford to test it.
What positions does the Sophia 4 offer?
The Sophia 4 supports zero gravity, raised-head, lounge, Trendelenburg, reverse Trendelenburg, and fully flat positions. The head and foot sections adjust independently, and the wireless remote makes it easy to find your ideal position. Multiple programmable presets let you save your favourite configurations. Come try all positions at our Brantford showroom.
Does the Sophia 4 include a vibro-massage feature?
Yes. The Sophia 4 has a built-in vibro-massage system with multiple intensity settings and targeted zones for the upper body and legs. It runs independently of the bed positioning, so you can use massage in any position.
What sizes are available and what does delivery include?
The Sophia 4 is available in Twin XL (38x80 inches), Double (54x74 inches), and Queen (60x80 inches). Call us at 519-770-0001 to confirm delivery details for your area.
What is the difference between a standard adjustable base and a multi-position base?
A standard adjustable base offers a few pre-set positions, while a multi-position base like the Sophia 4 provides a much broader range of adjustments. The Sophia 4 includes Trendelenburg, reverse Trendelenburg, full height adjustment, and independent head, foot, and lumbar control, giving you a higher level of customization for comfort, mobility, and home care needs.
What factors should I consider when choosing an adjustable base?
Consider the positions and functions you need, as some people want basic head and foot elevation while others require advanced adjustments for health or comfort. Verify the weight capacity supports your mattress plus the people using it. Other important factors include noise level, ease of use, available accessories like side-rails, warranty coverage, and after-sale service. The Sophia 4 checks every box with its lifetime structural warranty, whisper-quiet motors, and full accessory lineup. Call us at 519-770-0001 to discuss what matters most for your situation.
What type of mattress should I use with the Sophia 4?
Foam mattresses are the most compatible with adjustable bases. Orthex makes an orthopedic mattress designed specifically for the Sophia 4, available separately. If you already own a mattress, memory foam, latex, and hybrid options all work well. Avoid traditional innerspring mattresses as they do not flex properly. Check with your mattress manufacturer if you are unsure about compatibility, or bring your questions to our Brantford showroom at 441 1/2 West St.
What accessories are available for the Sophia 4?
The Sophia 4 offers fixed side-rails ($199.99 per set of 2), retractable short side-rails ($399.99 per set of 2), retractable long side-rails ($499.99 per set of 2), and a removable headboard and footboard kit with waterproof pale grey covering (headboards from $599.99, footboards from $399.99, each sold separately). All accessories can be added at any time after purchase. Visit our showroom to see them in person or call 519-770-0001.
