Is a Small Double Topper Right for You?

Small double mattress toppers are popular for a reason. If you’re wondering whether you could benefit from one, here are several signs that a small double mattress topper could be a great addition to your current mattress:

  • Your mattress feels too firm and needs extra cushioning
  • Your mattress lacks support and feels uneven
  • You experience pressure points around your shoulders, hips, or back
  • Your mattress is still usable, but it’s not as comfortable as it once was
  • You tend to sleep warm and want better airflow
  • You want to improve comfort without replacing your mattress
  • You’re looking for a simple and cost-effective way to improve your quality of sleep

Simbatex® Foam vs. Memory Foam

The materials used to make your small double mattress topper will make a world of difference in how comfortable, supportive, and breathable it feels throughout the night.

Traditional memory foam is by far the most widely used material in general mattress toppers, and it’s easy to see why. Memory foam has a great ability to wrap around your body and relieve pressure points. However, its dense structure is slow to adapt to movement and can restrict airflow, leading to the build-up of heat - both of which are major drawbacks.

That’s why we invented our own foam - Simbatex®. Unlike traditional memory foam, Simbatex® foam responds quickly to movement, allows 5x more airflow thanks to its open-cell structure, and is infused with graphite, which helps draw heat away from your body.

This makes our mattress toppers better for your quality of sleep in almost every way compared to general toppers made from traditional memory foam.

  • We have over 350,000 5-star reviews across the internet

  • What size is a small double mattress topper?

    A small double mattress topper is the exact same size as a small double mattress - 120cm (W) x 190cm (L). When it comes to thickness, it can vary from topper to topper, depending on the materials it’s made of.

  • Is a 4ft mattress topper the same as a small double topper?

    Yes, a 4ft mattress topper is the exact same as a small double topper in the UK. Both terms refer to a topper size of 120cm (W) x 190cm (L).

  • Can I put a Simba topper on any small double mattress?

    Yes, you can. All our small double mattress toppers are designed to fit standard small double mattresses perfectly, regardless of brand or manufacturer.

  • Is a mattress topper better than buying a new mattress?

    It depends. There are cases where investing in a mattress topper would be the better option than buying a brand-new mattress. There are also cases where a mattress topper simply won’t be enough to address the issues you’re facing.

    A mattress topper can be a great option if your current mattress is still in good condition, but it just needs a bit of improvement. For example, if your mattress is on the firmer side, doesn’t feel as comfortable as you’d like it to be, or could benefit from better temperature regulation, a quality topper can make a world of difference.

    However, if your mattress is old, sagging, or no longer providing the support that it once did, a topper is unlikely to fix the underlying problem, in which case buying a brand new mattress would be the better option.

  • How do I wash a small double mattress topper?

    Small double mattress toppers are usually very easy to wash and keep clean - at least that’s the case with Simba’s toppers. The exact washing process you’ll need to follow will depend on the topper you have.

    If you have a Simba topper, all you have to do is unzip the top layer and put it in the washing machine (on a program that is no more than 40°C). You can then either air-dry your Simba topper or tumble-dry it on a low setting.
