Single Bed Vs Small Double: 6 Reasons to Upgrade

Although they share the same length, small double mattresses are 30cm wider than single mattresses, unlocking a lot more sleeping space.

This extra space is equivalent to you sleeping on your side! Bliss when you want to stretch out without your arms and legs falling off the bed.

The bottom line is if you want to stretch out or sleep with someone else, a small double bed is a significant upgrade over a single bed. Single beds limit your sleeping space, while small double beds open it up without eating into the floor space too much.

Here are five reasons to upgrade to a small double:

  1. 30cm more sleeping space

While a single bed is 3ft wide and 6ft 3 inches long (90 x 190cm), a small double is 4ft wide and 6ft 3 inches long (120 x 190cm).

That 30cm extra sleeping space is equivalent to a person sleeping on their side, so it makes an enormous difference to bedtime comfort.

That extra 30cm will give you space to stretch out and sleep with someone else. Think of it as a direct upgrade over a single.

  1. Improve your sleep

Upgrading to a small double mattress is worth a go if you struggle to fall asleep in a single bed. If you struggle to sleep in a single bed, it might be because you feel restricted, making you toss and turn and feel anxious.

In addition to freeing up physical space, a bigger bed can free your mind and give you room to think and dream. It’s worth a go!

  1. Ideal for small bedrooms

If your bedroom is small, a small double is perfect for maximising floor space. Although small double beds are wider than single beds by 30cm, they are the same length, and the extra 30cm doesn’t eat up too much floor space.

You can maximise floor space even more by choosing a divan bed frame. Divan beds have a frame that is the same size as the mattress.

  1. Storage opportunities

Small double bed frames are available as divans and ottomans with built-in storage. An ottoman bed has a lift-up base, while divans have built-in drawers. It is rare for single beds to have storage because the frame is too small.

Again, this is ideal if you have a small bedroom. Built-in storage gives you space for pillows, bedding, shoes and seasonal clothes.

  1. Better for guests

A small double bed is always better than a single guest room because couples can stay over. Single beds are only good for single guests, so if you want to host couples and let them sleep over, a single bed really is no good.

  1. A great alternative to a double 

People tend to stumble on small doubles after looking at double mattresses. Double mattresses are only 15cm wider than small doubles, and they are the same length, so the difference isn’t as pronounced as you think.

If you have a small bedroom, a small double bed will be a better fit unless you have a big build, in which case a double will suit you better.

Other mattress considerations 

Now that you have settled on mattress size, it’s time to consider firmness.

Medium mattresses are best for most people, with medium-soft and medium-firm feels available to cater for everyone. Back and side sleepers are more suited to softer mattresses, while side sleepers suit firmer mattresses better.

Another consideration is mattress types. Pocket spring, memory foam, and hybrid mattresses are all good options. Pocket springs offer the best support and breathability but lack squishiness, which is where memory foam comes in.

Most mattresses use layers of springs and foam; a hybrid mattress is made with pocket springs and memory foam. The springs provide support while the foam delivers comfort.

A pure foam mattress uses no springs for more squishiness; these isolate movement (such as tossing and turning) the best and offer excellent support for heavy people.
