Buying a mattress used to mean an afternoon spent lying on a dozen beds in a showroom, feeling a bit self-conscious, while a salesperson hovered nearby. These days, most Australians skip that entirely and buy online — and for good reason. It's faster, often cheaper, and you can actually take your time deciding instead of feeling rushed.
But there's one question almost everyone asks before clicking "buy": how do I know it's right for me if I can't lie on it first?
It's a fair question. Here's exactly how to buy a mattress online with confidence — what to check, what to ignore, and how to make sure you end up with the right one.
Is it actually safe to buy a mattress online?
Short answer: yes, and it's become the norm rather than the exception. Online mattress brands remove a lot of the guesswork that showrooms don't actually solve anyway — lying on a bed for two minutes under fluorescent lights tells you very little about how it'll feel after eight hours of real sleep. What actually matters is different information: the materials used, the construction, genuine reviews from real customers, and clear warranty terms. All of that is available online — often more transparently than in a store, where pricing and stock can vary by location.
The key is knowing what to actually check before you buy, which is what the rest of this guide covers.
Step 1: Know your firmness and material preference
Before you even open a product page, get clear on two things: how you sleep, and what materials suit that.
- Back or stomach sleepers generally do best with firmer, more supportive mattresses — look for natural latex or a firmer hybrid build.
- Side sleepers usually prefer more cushioning at the shoulders and hips — a softer hybrid or memory foam comfort layer tends to suit better.
- Hot sleepers should prioritise breathable materials like natural latex and pocket springs over dense all-foam designs, which can trap heat.
- Couples benefit most from designs with strong motion isolation, like individually wrapped pocket springs, so one partner's movement doesn't wake the other.
If you want a deeper breakdown of the differences between mattress types, our guide on latex vs memory foam vs hybrid mattresses covers exactly how each one feels and who it suits.
Step 2: Get the size right
This is where most online mattress mistakes happen — not the feel of the mattress, but the size. A few things worth checking before you order:
- Measure your bed frame, not just guess the size. Frame dimensions can vary slightly between manufacturers, so measure the internal frame space if you're unsure.
- Consider your room, not just your bed. A King mattress needs meaningful clearance on all sides — measure your room, not just the frame.
- Check if you need a Single, King Single, Queen or King. If you're upsizing from a smaller bed, actually walk out the new dimensions on your bedroom floor with tape — it makes a bigger difference than people expect.
Full mattress sizes for the Felice range are listed on each product page, including exact dimensions in centimetres.
Step 3: Look past the marketing — check what actually matters
When you're comparing mattress listings online, a few details tell you far more than glossy photos or bold claims:
- What's actually in it. A listing should clearly state the materials — natural latex, memory foam, pocket springs, the cover fabric — not just vague terms like "premium comfort layers." If a brand won't tell you what's inside, that's worth noticing.
- The warranty length. A genuine, lengthy warranty (Felice mattresses come with a 10-year warranty) is one of the strongest signals of a brand's confidence in its own build quality. Be wary of very short or vague warranty terms.
- Real customer reviews. Look for reviews that mention specific details — firmness, delivery experience, how it felt after a few weeks — rather than generic five-star praise with no detail.
- Clear returns and warranty terms. Before buying anything online, read the seller's actual returns policy rather than assuming. Terms vary between brands, so check what's covered for faults versus change of mind. You can view Felice's Returns Policy here.
- Delivery transparency. A trustworthy seller tells you clearly how delivery works, how long it takes, and whether it's tracked — not just "fast delivery" with no detail.
Step 4: Understand how delivery works
One of the more practical worries with online mattress shopping is simply: how does a mattress even arrive? Modern mattresses are typically compressed and rolled for shipping, which makes home delivery far more manageable than people expect — no removalist van required.
At Felice, mattresses are delivered using trusted logistics partners with transparent, tracked shipping — you'll know where your order is at every stage, right to your door. If you're in Melbourne, fast local delivery is also available.
Step 5: Reduce your risk before you buy
You can't lie on the mattress before it arrives — but you can do a few things to make sure your decision is a well-informed one:
- Read the specific material details on the product page, not just the marketing copy.
- Check the warranty terms so you understand what's covered long-term.
- Read the returns policy in full before ordering, so there are no surprises.
- Reach out with questions. A legitimate mattress brand should be easy to contact before you buy, not just after. If you're unsure which mattress suits you, get in touch with the Felice team — a quick conversation can rule out a lot of uncertainty.
Common mistakes to avoid when buying a mattress online
- Buying on price alone. A very cheap mattress often means thin materials or a short lifespan — think in terms of cost per year of use, not just the upfront price.
- Skipping the size measurements. This is the single most common online mattress regret, and it's entirely avoidable with five minutes of measuring.
- Ignoring the warranty length. A long warranty is one of the clearest signals of build quality and brand confidence.
- Not reading the returns policy before ordering. Know what you're agreeing to upfront, not after a problem arises.
Frequently asked questions
Can I really know if a mattress is comfortable without trying it first?
You can't feel it in advance, but you can make a well-informed decision by checking the materials, firmness level, genuine customer reviews, and how the mattress is designed for your sleep position. Combined with a solid warranty, this significantly reduces the guesswork.
How long does mattress delivery take in Australia?
Delivery timeframes vary by location. Felice offers fast delivery to Melbourne, with tracked shipping to the rest of Australia.
What size mattress should I buy?
It depends on your bed frame and bedroom space, not just how many people will use it. Measure your existing frame or bedroom floor space before choosing between Single, King Single, Queen and King sizes.
What if the mattress doesn't suit me once it arrives?
Return and warranty terms vary by seller, so it's important to read the Returns Policy in full before ordering, and to reach out to customer support with any questions beforehand.
Is buying a mattress online cheaper than in-store?
Often, yes — online mattress brands typically have lower overheads than physical showrooms, which can mean better pricing for the same or better quality materials.
