Best HSA-Eligible Mattresses (2026 Guide)

A mattress can qualify for HSA or FSA reimbursement when a licensed clinician ties it to a diagnosed condition in a Letter of Medical Necessity: chronic back pain, sleep apnea, post-surgical recovery, fibromyalgia or another sleep-impacting condition. A general bed is furniture; a documented one is a medical expense. Buy the mattress you want from any store with any card, and Burst gets you the letter for $35 and files the reimbursement. Below: which brands fit which conditions and what your letter needs to say.

Hi, I'm Shubhi, one of the co-founders at Burst. This guide is for anyone shopping for a new mattress, or already paying for one, who's heard that FSA or HSA dollars might cover it.

If that already describes you, the request takes about two minutes.

Why mattresses qualify with an LMN

The IRS rule (Publication 502 + Notices 2006-69 and 2007-2) is that medical expenses include anything that treats, mitigates, or alleviates a specific medical condition. A general bed is furniture. A mattress purchased to manage chronic back pain, sleep apnea, post-surgical recovery, fibromyalgia, or another sleep-impacting condition is medical equipment, when documented.

What changes the IRS view is the LMN. A short note from a licensed clinician naming the condition and connecting the mattress purchase to it. Plan administrators will reimburse against this documentation.

What a mattress really costs with Burst

Say the mattress is $1,200 and your combined federal and state marginal rate is about 30%. Paying for it from a pre-tax account means roughly $360 of income tax you never pay. The letter is $35, once, and covers the item for 12 months.

Your actual savings depend on your plan and your bracket. This is an estimate, not a quote.

Letter of medical necessity for a mattress

The letter names your diagnosed condition (chronic back pain, a herniated disc, arthritis, fibromyalgia, sleep apnea or another sleep disorder, or pressure-related skin conditions) and states that a supportive mattress is part of managing it. It does not name a brand, so Nectar, Saatva, Tempur-Pedic, Purple, Helix, Casper and the rest all fit. Adjustable bases can be named in the same letter when positioning is part of the plan. Buy after the letter's date and Burst files the claim with the receipt.

Adjacent eligible items

• Mattress toppers: same eligibility rules as mattresses; an LMN works.

• Adjustable bed bases: eligible when the LMN names a condition (acid reflux, sleep apnea, post-surgical recovery) the elevation supports.

• Memory foam pillows: eligible with an LMN naming neck pain or post-surgical recovery.

• Cooling sheets and mattress protectors: typically not eligible alone, but when bundled with an LMN-covered mattress on the same receipt, the bundle reimburses together.

What's not eligible, even with an LMN

• Bed frames as decorative furniture. An adjustable base can be eligible. A static decorative frame is not.

• General bedding (regular sheets, decorative pillows, comforters). Comfort items, not medical.

• Subscription replacements bought outside the LMN window. Once the LMN expires, the next purchase needs a refreshed LMN.

What your LMN needs to say for a mattress

The mattress LMN that gets approved names the specific sleep-related health situation and connects the mattress purchase to it. "Recommended for better sleep" gets denied. "Required for management of chronic low back pain documented by [provider]" gets approved.

Common health situations on mattress LMNs:

• Chronic low back pain or neck pain

• Sleep apnea (especially with adjustable base)

• Fibromyalgia and chronic widespread pain

• Post-surgical recovery

• Arthritis (osteoarthritis or rheumatoid)

• Sciatica or peripheral neuropathy

• Insomnia tied to a documented context

• Perimenopausal or menopausal sleep disruption (Eight Sleep specifically)

Common mattress FSA/HSA pitfalls

• Submitting the financing receipt. If you finance through Affirm or Klarna, submit the original mattress receipt to your plan admin, not the monthly installments.

• Forgetting the topper. A mattress topper bought alongside the mattress reimburses too on the same LMN.

• Letting the LMN expire before a recurring purchase. If you're switching mattresses or buying a topper after 12 months, refresh the LMN first.

• Buying a frame instead of a base. A medically-justified adjustable base is eligible. A decorative frame is not.

Mattress FSA/HSA FAQ

Are mattresses FSA eligible without an LMN?
No. Mattresses are dual-purpose under IRS rules. The LMN is what creates eligibility.

Can my plan admin deny an LMN-backed mattress reimbursement?
It happens, usually because the LMN is too vague. Burst's clinicians write letters that name the condition and the item specifically, which is what administrators want to see. If one pushes back, we write the appeal.

Is Eight Sleep specifically harder to get covered than a regular mattress?
No, the path is the same. Eight Sleep just has a more specific use case (cooling, sleep tracking) which often makes the LMN easier to write because the medical context is clear.

Does the LMN cover the entire mattress price?
The LMN doesn't set a dollar limit. Your reimbursement is the actual mattress receipt, capped only by your FSA or HSA balance.

Can I get an LMN for a mattress I already bought?
Per IRS guidelines, LMNs must be for purchases made on or after the LMN request date. If you're planning to buy soon, get the LMN first.

Is the LMN fee itself FSA/HSA eligible?
Yes.

Will my HSA or FSA administrator accept it?
Yes. Administrators want a signed letter from a licensed clinician that names your condition and the item, and that is exactly what you get. Burst works with every FSA/HSA administrator, including HealthEquity, Fidelity, WEX, HSA Bank, Inspira, Optum and Further. If one pushes back, we write the appeal. If the claim is denied, you get your $35 back.

What if I am not approved?
You pay nothing. No letter, no charge.

Who files the reimbursement claim?
We do, start to finish. Send us the receipt and Burst files the claim with your administrator; the money comes back to your bank account.

Stop paying full price for your mattress

If you've got a sleep-impacting condition and you're already paying for a quality mattress, the letter is what lets you pay for it from your pre-tax account. $35 once, about two minutes, and your letter usually arrives the same day. No letter, no charge.
