What’s the Simba mattress made from?

All the layers are CertiPUR certified, meaning they’re tested to the highest standards to make sure they are from harmful chemical and materials like mercury and lead. The mattress is made in the UK, and Simba’s manufacturer is apart of the national bed federation. The NBF contributes to the education and safety of both the trade and consumers.

Simbatex® layer – Simba’s trademarked top layer is now an open-Cell polyfoam that use to be 100% synthetic latex. The open-cell polyfoam is preferred to regular polyurethane foam because it allows more air to flow through it, making the layer disperse heat better.

The Simba miQro® spring – The 2,500 conical pocket springs (based on King Simba hybrid mattress) adds bounce and responsiveness to the bed. Springs also last longer than foam, so they add a lot of durability to the bed along with pressure relief because they work when pressure is applied.

Simba pattered the design of the unique coils, and the springs are contained in polyester pockets to keep them in zones and facing the right way up. The cone-shaped of each spring allows the spring to collapse flat, which is essential for the layer not to take up much room. The steel that makes up this layer is 100% British and produced in Leeds.

Usually, the addition of springs translates to a slightly firmer bed which is common in hybrid mattress. However, the more springs mean your weight is spread out more, leading to each spring compressing less, giving a softer feel.

Polyurethane Foam Layer – This is the transitional layer between the base and the springs, which is polyurethane-based foam for support, better airflow, and reduced heat retention in the bed.

Before this layer used to be memory foam which would retain heat and respond to the body more, this left the mattress with little edge support, so the upgrade to polyurethane foam is an excellent upgrade.

High-density polyurethane foam – The bottom layer is the supportive base that adds durability, and you guessed it, support to the bed. The base is castellated, which means it has channels cut through it also called zoning. This increases airflow and cools the mattress, but more importantly, it relieves pressure for your shoulders, hips, and correct spine alignment.

The cover – As much thought goes into the cover as the mattress, the cover is 100% polyester, free from harmful chemicals, and is hypoallergenic – which means fewer allergic reactions.

The cover is white on top with grey sides, the top is very soft to the touch and is very stretchy, while the sides are more durably and reinforced with 4 handles to make moving the bed about much more comfortable.

Sadly, the cover is not washable. If you need to clean the cover, it’s best to spot clean, if you are getting the bed for children we recommend using a mattress protector to keep your Simba bed clean.

Thickness and weight

The Simba Hybrid mattress is heavier than an all-foam mattress because of the springs. However, it’s lighter than other hybrid mattresses weighing in at 38 kg for the king compared to the OTTY 45 kg.

How long does it take to inflate?

After you take the mattress out of the box and out of the vacuum wrapper, it begins to expand quickly. Before sleeping on it, leave it for 3-6 hours to expand. It takes about 24 to 48 hours to fully inflate, but it’s deep, comfy, and ready to sleep on after three hours.

Can you leave it in the box?

Please keep in mind that your 200-night trial begins on the day of delivery, regardless of whether you have opened the box or not. The mattress can stay in the packaging for up to three months. However, the earlier you open it, the sooner you’ll enjoy a restful night’s sleep!

Is the Simba mattress right for you?

We have found out that the overall feel of the mattress is medium that works for the majority of side, and back sleepers. However, it’s appropriately better for side sleepers because of the pressure relief around the shoulder area, and it could be too soft for front sleepers, but that’s a personal preference.

I would recommend the Simba Hybrid mattress to sleepers if:

You love a softer hybrid mattress – The mattress is great if you’re looking for a medium feel mattress which doesn’t usually happen in a hybrid, they tend to be firmer. However, the design of the micro springs helps soften the bed in comparison to regular hybrids.

You want a cold bed –  The smart design of the bed optimises airflow to circulate for a more refreshing nights sleep.

Motion transfer – Simba hybrid mattresses are excellent for minimal partner distance, so if your partner moves around a lot in the night, it won’t wake you up.

You like medium firmness – Simba is a medium feel mattress around (5.5/10) which is soft for a hybrid mattress.

Homegrown – The Simba mattress originated from the UK company in the bedding industry since 1979. However, the Simba sleep brand started in 2015 by James Cox and Andrew McClements.

Chemical-free – Simba foams are CertiPUR certified, so it’s free from nasty chemicals in the mattress.

Is the Simba Hybrid good for back pain? From the reviews, we would say it does a great job, and if you look at the design, you can see why. The zoning of the mattress and pressure-relieving micro springs help key area on your body.

In the end, Simba Sleep is a great UK company with plenty of 5-star reviews, and the bed comes with a generous 200 night trial period to test if its right for you, for the price we think it’s well worth the money.
