Criteria for choosing a mattress for a guest bedroom
As with all mattress choices, there are a certain number of criteria you may wish to consider when choosing a mattress for your guest bedroom.
Comfort
Of course, the mattress in your guest bedroom should be comfortable. You wouldn’t want your family or friends sleeping on an uncomfortable mattress!
So our general rule of thumb is that you should find the mattress comfortable yourself. Try it for a night — if you don’t like it, it’s probably not a good choice.
You don’t have to buy a luxury mattress, like a Tempur, but, still, pay attention to the quality and comfort level of the mattress you decide on.
Many online retailers offer risk-free trial periods, which give you the chance to try the mattress to see if it’s right.
Universality
Since the people visiting you will all have different bodies, needs, and sleeping preferences, it’s important to choose a mattress that’s universal enough to work for a wide range of people and sleeping positions.
Choose a medium-firm mattress of the universal kind that’s neither too firm nor too soft.
Size
Not everyone is blessed with luxuriously large guest bedrooms. It’s likely that your guest bedroom is small, so it’s important that you have a mattress that’s space-savvy. The UK Double Mattress (135 x 190 cm) is a good space-saving option.
If you don’t have a guest bedroom but still need a guest mattress, then you can also consider camping beds.
Foldable beds and air mattresses can be set up easily and stored in a cupboard, but they’re not ideal for sleeping in the long term.
You can also choose a futon, a sofa that folds out into a bed.
Price
While you certainly can splurge on a mattress for a guest bedroom, your spare mattress does not have to be expensive.
There are many high-quality mattresses available at very affordable prices.
Why would you choose an inflatable mattress?
Inflatable mattresses are great as they’re very space-efficient. You can pack them away if you don’t need them and easily set them up if you have visitors.
Before buying an inflatable mattress, though, you should think about the size and the height of the mattress as well as the inflation technique.
You’d want something that’s quick and easy to set up to accommodate overnight visitors and something that’s very comfortable.
Why would you choose a foldable mattress?
Foldable mattresses are often very thin but can be quite comfortable.
They’re also very space-efficient and can be stored away quite easily. Foldable mattresses can be made of a variety of materials.
Converting a small room into a guest bedroom
You don’t need a large space to create a beautiful guest bedroom. If done right, even a small area can be optimised.
If the room is very small, don’t bother installing cupboards or a dressing table — these just take up unnecessary space. You could install a clothing rail, if you wish, or add in a chair and small table.
If a bed and mattress fit, then you’re in luck. If not, you may consider using a futon, which can be folded back into a sofa during the day, or making use of a foldable or inflatable mattress.
For decorating, we’d recommend using neutral or soft colours. White or beige walls tend to lighten up the room and enhance the space.
To create a cosy room, dress the mattress with sheets, a duvet, and cushions. This will turn even the smallest space into a comfortable bedroom.
Conclusion
There are dozens of mattresses you can choose for your guest room.
If you’re struggling with space, then a futon, inflatable, or foldable mattress are good options. But if you do have space for a full bed and mattress, no matter what size, then it’s always worth investing in a high-quality mattress at a reasonable price.
Many of the mattresses in our mattress reviews will be suitable, including the best-selling Emma Original and Eve Original, but if you’re really looking for the best value for money, then you can’t do better than the Eve Lighter Hybrid.
