Information and customer service

The mattress listing includes plenty of description, and there is plenty of information about how the mattress is constructed, the materials and the different layers.

I also found the customer service was great and the delivery guys were helpful. Delivery is free and they claim that all their deliveries are ‘completely carbon neutral’. While they didn’t carry the mattress upstairs, it was very easy for us to do it.

The mattress came vacuum-packed in a box, but it was very light and the box had handles for easy carrying. They also offer old mattress removal in most parts of the UK, but I didn’t use this service.

Simba offer a ‘risk-free 200-night trial’, which is one of the longest periods offered on the mattresses we tested – collection is free and it doesn’t need to be repackaged. (7 out of 7 points)


The Simbatex essential foam mattress is made with open cell Simbatex® foam, which provides 30x more airflow than standard memory foam; it’s also infused with graphite, which has an excellent ability to draw away excess heat.

All the foam used in the construction of the mattress is verified as free from CFCs and other ozone-depleting substances, and ensures lower emissions to protect indoor air quality. Simba mattresses are 100% recyclable too, and deliveries are carbon neutral. The company even says that ‘leftover foam is used in the manufacture of carpet underlay or pet beds’, ensuring nothing goes to waste.

The cover is removable – there’s a zip that opens all the way to the middle – so it’s easy to wash.

When it comes to turning the mattress, it’s important you rotate it regularly in order to keep the 10 year warranty valid: you need to turn it by 180 degrees each month for the first three months, and then every three months for the rest of its life.

This mattress is available in Single, Double, King and SuperKing, and with a depth of 19cm, was one of the deepest memory foam mattresses we tested. (5 out of 6 points)

Specifications: W135cm, L190cm, D19cm.

The results

The mattress came vacuum-packed in plastic and was really small and compact compared to the actual size of the mattress. The convenient size of the packaged mattress means that if you needed to be out when it was delivered, it could easily be left with a neighbour or in a porch or shed.

The memory foam mattress didn’t have any smell at all when unpacked, and the cardboard box was very easy to recycle with our regular cardboard recycling, however the plastic wrapping unfortunately went into the rubbish bin.

The instructions were very clear and easy to understand. It is a memory foam mattress so in about 4 hours it had expanded to normal size. The website advised leaving it for 72 hours before sleeping on it but I didn’t leave it for this long before sleeping on it and I didn’t notice any loss of comfort.

Considering it claims to be a supportive mattress, both my partner and I found it firm and comfortable for our different sleeping positions. (5 out of 5 points)

Value for money

Simba offer a 10-year warranty, and given the 200-night free trial as well as the quality and comfort, I think it’s a very good mattress and worth the money. I am very happy with it. (2 out of 2 points)

What to look for in a budget mattress?

Memory foam and all-foam mattresses tend to be among the cheaper, more affordable on the market, so if budget is tight then check these out against your sleeping requirements before you take the plunge. For budgets under £500, check out Emma’s award winning Original mattress, which combines 3 layers of foam as well as memory foam, Mattressman’s Healthopaedic mattress, which combines memory foam and pocket springs, and also Dusk’s hybrid mattress. Even on a budget you should be able to find a top solution for your best night’s sleep.

What to look for in a mattress for back pain?

If you suffer with back pain then a memory foam mattress could be the best solution for you. Its super reactive and will mould to your body’s shape and sleeping position, giving you the support exactly where you need it. Hybrid mattress that combine memory foam and pocket springs is another solution that can help to relieve any spinal discomfort. Look for a mattress that’s more firm to prevent your spine from dipping and maintaining its alignment.


If you’re a side, front, back sleeper – what type of mattress should you be looking for?

If you’re a side sleeper choose a mattress with a soft to medium comfort level, memory foam and gel foam can provide the responsive support you need for the more vulnerable pressure points around your shoulders, hips and thigh. Front sleepers are more prone to back pain, so a medium firm mattress can help support your spine. Avoid being able to sink in too far into your mattress, so opt for a hybrid of memory foam and pocket springs to ensure your weight is evenly distributed. Back sleepers need a medium to very firm mattress to ensure lower back pain is kept at bay! You should also consider your weight when choosing a mattress as a back sleeper – as a rule, the heavier you are the firmer your mattress should be. Don’t allow your spine to sink too far into the mattress as this can cause misalignment and further back pain.
