Hospital Bed Mattress

How to choose a hospital bed mattress

The right mattress comes down to three things: the size that fits your frame, the surface that suits the person using it, and how much support and weight capacity you need. Here is how the common types compare.

Most common

Foam

A solid foam core, often with a fluid-resistant cover.

  • Lightweight and easy to reposition
  • Quiet, no power needed
  • A budget-friendly replacement option

Best for: everyday home use and simple mattress replacement.

Cooler surface

Gel-infused foam

Foam with a gel layer worked into the top surface.

  • Sleeps cooler than plain foam
  • Added surface cushioning
  • Still light and power-free

Best for: people who run warm or want extra top-surface comfort.

Firmer feel

Innerspring

A coil core with foam padding, a traditional mattress feel.

  • Firmer, more familiar support
  • Good edge support for sitting
  • Durable everyday surface

Best for: those who prefer a conventional, firmer mattress.

Get the size right

Measure the inside of your bed frame before ordering. Most home hospital beds use a 36 in. wide by 80 in. long mattress. Some beds fit a twin XL, and bariatric frames use wider sizes.

Match the weight capacity

Standard mattresses suit most users. For a heavier user or a bariatric frame, choose a wider, higher-capacity mattress rated for the weight. Ask us if you are unsure.

Consider the cover

Many mattresses include a fluid-resistant, wipe-clean cover that helps with everyday cleaning. This is a practical feature for home caregiving.

Spending most of the day in bed?

If the priority is pressure redistribution for someone with limited mobility, a specialized surface may be a better fit than a standard mattress. See our pressure-relief mattresses or powered low-air-loss mattresses, or call us and we will help you compare.

Hospital bed mattress questions

What size mattress fits a hospital bed?
Most home hospital beds use a mattress that is 36 inches wide by 80 inches long. Some frames fit a twin XL, and bariatric frames use wider sizes such as 42, 48, or 54 inches. Always measure the inside of your bed frame before ordering, and if you are unsure, call us and we will confirm the fit.
What is the difference between foam, gel, and innerspring mattresses?
Foam mattresses are lightweight, quiet, and a budget-friendly choice for everyday home use. Gel-infused foam adds a cooler top surface and extra cushioning. Innerspring mattresses use a coil core for a firmer, more traditional feel with good edge support. The best choice depends on the user's comfort preference and how the bed is used.
How do I choose a replacement mattress for a hospital bed?
Start with the size of your current mattress and the inside dimensions of your frame, then pick the surface type and weight capacity that fit the person using the bed. If you are replacing a worn mattress, matching the size and cover type you already have is usually the simplest path. We are happy to help you match a replacement over the phone.
How thick should a hospital bed mattress be?
Home hospital bed mattresses are commonly 5 to 6 inches thick. Thickness matters because your bed's side rails need to stay tall enough above the mattress to work as intended, so check your side-rail height when choosing a mattress.
Are hospital bed mattresses waterproof?
Many hospital bed mattresses include a fluid-resistant cover that wipes clean, which is a practical feature for home caregiving. Cover materials vary by model, so check the individual product details or ask us which options have a wipe-clean cover.
I need a mattress to help with pressure or bed sores. Which page should I look at?
For someone with limited mobility who spends most of the day in bed, a specialized surface may suit them better than a standard mattress. See our pressure-relief mattresses or powered low-air-loss mattresses, and call us if you would like help comparing the options for your situation.
Do I need a prescription to buy a hospital bed mattress?
No prescription is required to purchase a hospital bed mattress from us. If you plan to seek reimbursement, insurance and Medicare coverage rules vary, so check with your plan about what documentation they require.
Can I buy or rent, and do you deliver?
You can buy a hospital bed mattress outright, and we can talk through rental for short-term needs. We offer local delivery and setup across the Salt Lake Valley, and we ship nationwide with free shipping. Call 801-906-3900 and we will help you order the right size.
