Quick Answer: A mattress or adjustable bed can qualify as a CRA medical expense if a licensed medical practitioner prescribes it as medically necessary for a diagnosed condition before you purchase it. Standard mattress purchases do not qualify. You claim on Line 33099 or 33199, and the 2026 threshold is $2,890 or 3% of net income, whichever is less.

Does a Mattress Actually Qualify? The Honest Answer
Most mattress purchases do not qualify for the CRA Medical Expense Tax Credit. If you are buying a mattress because your old one is worn out, because you want a better night's sleep, or because you read that a certain firmness is good for back pain, that is a personal purchase, not a medical expense.
A mattress qualifies only when all of the following are true:
- A licensed medical practitioner has diagnosed you with a specific medical condition
- That practitioner has determined, in their professional opinion, that a specific type of mattress or adjustable bed is medically necessary for that condition
- They have provided a written prescription or letter before you make the purchase
- The device you buy matches what was prescribed
In our experience at Mattress Miracle, the customers who successfully claim mattresses on their taxes have conditions like diagnosed disc herniation, spinal stenosis, severe GERD requiring elevation, post-surgical recovery needs, or documented sleep apnea where an adjustable bed complements CPAP therapy. A general complaint of "bad back" is not enough. The CRA wants specificity.
CRA Eligibility Rules for 2026
The Medical Expense Tax Credit (METC) is governed by Section 118.2(2) of the Income Tax Act. According to the CRA's published guidelines (RC4065, Medical Expenses), eligible expenses include devices, equipment, and supplies that are:
CRA Eligibility Criteria
- Prescribed by a medical practitioner. The CRA publishes a list of authorized medical practitioners by province. In Ontario, this includes physicians, chiropractors, physiotherapists, and other regulated health professionals.
- Required for the patient's medical condition. The key word is "required," not "recommended" or "beneficial." The practitioner must state medical necessity, not preference.
- Not available for reimbursement elsewhere. If your insurance or WSIB covers the mattress, you cannot also claim the unreimbursed portion through METC (you can only claim the portion you actually paid out of pocket).
2026 Threshold
You can claim eligible medical expenses that exceed the lesser of:
- $2,890 (the 2026 federal threshold), or
- 3% of your net income (Line 23600)
The tax credit is calculated at 15% of eligible expenses above the threshold. For example, if you purchase a prescribed adjustable bed for $3,500 and your threshold is $2,890, the eligible amount is $610, and the federal tax credit is approximately $91.50. Provincial credits vary.
This is not a deduction. It is a non-refundable tax credit, which means it reduces the tax you owe rather than reducing your taxable income. If you owe less tax than the credit amount, the unused portion does not result in a refund.
The Documentation You Need (Before You Buy)
This is where most people's claims fail. The CRA requires documentation to be in place before the purchase, not after. Here is what you need:
Required Documentation Checklist
- 1. Prescription letter from a licensed medical practitioner. This must be dated before your purchase date. It should name the specific condition (e.g., "L4-L5 disc herniation," "diagnosed GERD with nocturnal aspiration risk," "post-total hip arthroplasty requiring adjustable positioning"). A letter that says "patient would benefit from a better mattress" is not sufficient.
- 2. The prescription must specify the type of device. "Pressure-relieving mattress with zoned lumbar support" or "adjustable bed base capable of 30-degree head elevation" is specific. "A good mattress" is not.
- 3. Detailed purchase receipt. Your receipt should include the item description, date of purchase, amount paid, and the store's name and address. Mattress Miracle provides detailed invoices that include product specifications.
- 4. Manufacturer specifications. If the CRA reviews your claim, they may request documentation showing the mattress meets the medical requirements in the prescription. Keep the product spec sheet.
Do not send these documents with your tax return. Keep them filed for at least 6 years. The CRA may request them if they review your return.
How to Claim on Your Tax Return
According to the CRA's published filing instructions:
- Gather all eligible medical expenses for any 12-month period ending in the tax year
- Calculate the total and subtract the threshold ($2,890 or 3% of net income)
- Enter the result on Line 33099 (for yourself, your spouse/common-law partner, or your children under 18) or Line 33199 (for other dependants)
- The federal credit is 15% of the eligible amount above the threshold
- Provincial credits are calculated separately and vary by province
If you use tax preparation software like TurboTax, SimpleTax (Wealthsimple Tax), or H&R Block, the medical expense section will walk you through the calculation. If you file with an accountant, provide them with the prescription letter and receipt.
Adjustable Beds and the METC
Adjustable beds have a stronger case for METC eligibility than standard mattresses because they are more clearly "medical devices" in function. Hospital beds are explicitly listed as eligible medical expenses in the CRA's guidelines. While a home adjustable bed is not identical to a hospital bed, the functional overlap is significant.
Conditions Where Adjustable Beds Have the Strongest METC Case
- Post-surgical recovery: The Canadian Institute for Health Information (CIHI) reports 175,242 hip and knee replacements in Canada in 2024-2025. Patients discharged after joint replacement, cardiac surgery, or abdominal procedures often need adjustable positioning at home that mirrors what they had in hospital.
- GERD with nocturnal aspiration risk: Research in Sleep Medicine Reviews confirms that head elevation reduces acid exposure by up to 65%. When a gastroenterologist prescribes elevation therapy, an adjustable bed is the most effective implementation.
- Congestive heart failure: Head elevation reduces cardiac preload. Cardiologists routinely prescribe elevated sleeping for heart failure patients.
- Severe sleep apnea: The Journal of Clinical Sleep Medicine documents that positional therapy including head elevation complements CPAP. When a sleep specialist prescribes both CPAP and positional elevation, the adjustable base supports the treatment plan.
- Spinal conditions with prescribed positioning: The Canadian Chiropractic Association and orthopaedic surgeons may prescribe specific sleep positioning for degenerative disc disease, spinal stenosis, or post-spinal-surgery recovery.
The key in all cases is that a practitioner prescribes the specific device for a diagnosed condition. Buying an adjustable bed because you saw an ad is not a medical expense. Buying one because your cardiologist wrote a prescription letter for nocturnal head elevation for diagnosed CHF is.

Frequently Asked Questions
Can I claim any mattress as a medical expense?
No. Only mattresses prescribed as medically necessary by a licensed practitioner for a diagnosed condition qualify. A standard mattress purchase for comfort or replacement does not qualify, regardless of the price or features.
Do I need the prescription before I buy the mattress?
Yes. The CRA requires the prescription to be dated before the purchase date. If you buy first and get a letter after, the claim may be denied.
Can a chiropractor write the prescription?
In Ontario, chiropractors are on the CRA's list of authorized medical practitioners for certain medical expenses. However, eligibility depends on the specific expense and provincial regulations. Check the CRA's authorized practitioners list or consult a tax professional.
How much will I actually save on my taxes?
The federal credit is 15% of eligible expenses above the threshold ($2,890 for 2026 or 3% of net income, whichever is less). Provincial credits add to this. For a $3,000 adjustable bed where the threshold is $2,890, the federal credit would be approximately $16.50. For larger expenses or when combined with other medical expenses that exceed the threshold, the credit can be more significant.
Can I claim if my insurance covered part of the cost?
You can only claim the portion you paid out of pocket. If insurance reimbursed $1,500 of a $3,000 purchase, your eligible expense is $1,500 (minus the threshold).
