Hotel Mattress Toppers - Find the Right Fit for How You Sleep

Not all mattress toppers are the same. The best mattress topper for you depends on how you sleep, how warm you run, and what your mattress is missing. Mainlinen supplies hotels, resorts, and Airbnb hosts across Australia and makes the same toppers available to home shoppers. Three options. Each built for a different kind of sleeper.

Guest Comfort Mattress Topper - 1000GSM Down Alternative

The most popular mattress topper in our range, and a firm favourite with both our hospitality clients and home shoppers.

At 1000GSM, the Guest Comfort sits at the premium end of the fill-weight spectrum - high enough to add visible, pillowy loft to any mattress, without the allergens or maintenance of real feather and down. The Japara cotton cover is breathable by design, making it a comfortable option for most sleepers across different seasons.

If you’ve been searching for the best mattress topper in Australia, this is the one hoteliers reach for. Boutique properties and home bedrooms across the country trust it for the same reason: it noticeably transforms the feel of a bed.

Who it's for:

• Anyone upgrading a firm, ageing or underwhelming mattress
• Back and side sleepers who want a softer comfort layer without losing support
• Allergy-sensitive sleepers who can't use feather or down
• Airbnb hosts and hotel managers wanting guests to ask what they did to the bed

Key Features:

• 1000 GSM down-alternative microfibre fill
• Japara cotton cover - breathable and smooth
• 5cm profile adds noticeable depth, loft and sink-in feel
• 40cm deep-fit skirt - no shifting, no re-rucking

Guest Fresh Mattress Topper - 850GSM Microfibre Softness

The Guest Fresh is built for one thing: plush, cloud-like softness. At 850GSM, it adds a generous layer of cushioning that immediately transforms the feel of a flat or ageing mattress.

This is a comfort-first topper - deeply soft, insulating, and ideal for cooler climates or sleepers who love to feel cocooned. If you run warm at night, the Guest Comfort’s Japara cotton cover is a better fit.

Key Features:

• 850GSM premium microfibre fill
• Soft, smooth microfibre casing
• 40cm stretch sidewall for a secure fit
• Hypoallergenic

Frequently Asked Questions About Mattress Toppers

Q: What is the best mattress topper in Australia?

The best mattress topper depends on how you sleep. For most people, the Guest Comfort 1000GSM down-alternative is the top pick - it adds significant loft and uses a breathable Japara cotton cover, making it suitable for a wide range of sleepers. If you prefer a deeply cushioned feel and sleep cool, the Guest Fresh 850GSM is a great option. For those who prefer natural fill, the Holiday Inn Feather & Down delivers exceptional softness.

Q: What does GSM mean in a mattress topper?

GSM stands for grams per square metre and refers to the fill weight of the topper. A higher GSM means more fill, more loft, and a plusher feel. Our Guest Fresh sits at 850GSM and our Guest Comfort at 1000GSM, both considered premium fill weights.

Q: What is the difference between 850GSM and 1000GSM?

The 1000GSM Guest Comfort has more fill, giving it a deeper, more lofted profile. It also features a Japara cotton cover which is more breathable than the standard microfibre casing on the 850GSM Guest Fresh. If softness and cushioning are your priority and you tend to sleep cool, the 850GSM is a solid choice. If you want maximum loft with added breathability, the 1000GSM is the better fit.

Q: Are Mainlinen mattress toppers hypoallergenic?

Yes, both the Guest Fresh and Guest Comfort are filled with hypoallergenic microfibre, making them suitable for allergy-sensitive sleepers. The Holiday Inn Feather & Down topper contains natural feather and down and is not recommended for allergy sufferers.

Q: Do mattress toppers fit deep mattresses?

Yes. All Mainlinen mattress toppers feature a 40cm deep-fit skirt, designed to fit snugly over most standard and deep mattresses without slipping or bunching.

Q: Can I return a mattress topper if it doesn’t suit me?

For health and hygiene reasons, mattress toppers cannot be returned once opened. We recommend reaching out to our team before purchasing if you’re unsure which topper suits your sleep style - we’re happy to help you choose.

Q: What mattress topper do hotels use?

Mainlinen supplies mattress toppers to hotels, resorts, and accommodation providers across Australia including Holiday Inn properties. The Guest Comfort 1000GSM down-alternative and the Holiday Inn Feather & Down are both used in professional hospitality settings.

Q: Is a down alternative mattress topper good for hot sleepers?

Down-alternative toppers vary depending on the cover fabric. The Guest Comfort uses a Japara cotton cover which is more breathable than standard microfibre. However, all mattress toppers add an insulating layer - sleepers who run particularly warm should consider this before purchasing. If you’re unsure, contact our team before buying.
