A sofa bed can certainly help you save on space – you’re basically getting two pieces of furniture in one. They’re also perfect for your guests to sleep on, or even you if you spent an evening bingeing shows on your sofa.
One problem many sofa beds have, however, is that their beds can be a little on the firm side. Sleeping on them isn’t exactly the world’s more comfortable experience.
A good mattress topper can make them much cosier, though. We’ve done the research and found the best mattress toppers for sofa beds in the UK.
Let’s take a closer look at them.
Quick Recommendation

Don’t want to read right now? This is our quick recommendation: the High Living Microfibre Mattress Topper. No products found.
It’s the thickest mattress topper on our list, which means there’s more between you and the stiff mattress beneath it. Furthermore, it has box stitching that prevents the filling from bunching up in different areas.
What to Remember When Buying a Mattress Topper for a Sofa Bed
Cleaning
One of the biggest grievances with anything you use for your bed, whether it’s sheets, pillows, or comforters, is how difficult they can be to clean. Some of the products can’t be put in your washing machine for a quick spin – they need to be washed by hand or even dry cleaned.
Don’t have time to hand wash something or drop it off at a dry cleaner? Then make sure to confirm in the description whether or not your mattress topper is machine washable.
If it is, then cleaning up after an evening of napping on your sofa is as easy as putting the topper in a machine and letting it take care of the rest.
Filling
Just like the mattresses themselves, toppers come with a variety of fillings. Each type will have an influence on how it feels to lie on the topper.
Memory foam, for instance, is a popular filling. It will shape to your body, providing you support that feels as if it was made for you. The downside is that it can sometimes get expensive.
Down or feathers are another common topper filling. You’ll feel like royalty when you’re nestled in a bed of down, but later on, the feathers can start poking through the topper.
Size
Mattress toppers come in huge range of sizes, and this doesn’t just mean surface area. Although it’s important that your mattress topper is large enough to cover your sofa bed, you’ll also want to consider thickness.
Thickness will determine how much cushioning there is between you and the sofa bed. The thicker the topper, the less you’re going to feel the firm mattress underneath.
A mattress topper’s thickness can range anywhere from a couple to several centimetres.
Hypoallergenic Features
Even if you don’t personally have problems with allergies, non-allergenic features are worth thinking about for your mattress topper. If you ever have a guest with allergies, they’ll thank you for the comfort a hypoallergenic mattress topper can provide.
Usually, the description for each mattress topper will mention whether or not it uses non-allergenic materials.
