This is a 6-month review so I am leaving my assessment based on sound experience of using this product, and a lot has happened! I purchased the Simba mattress and pillow after hearing all the hype surrounding it with high hopes of getting a good night's sleep and waking up feeling refreshed. However, my experience with these products has been nothing short of a nightmare and I do not recommend them. Financially I feel like I have been robbed by an overpriced and overmarketed product. I hope I am still eligible to win back the cost of my Simba for the following reasons: Here is my timeline: Mattress: The bed arrived on 16 June 2023. The bed was unrolled and left in the spare bedroom to expand. The bed was put into the master bedroom on 19th June and my partner started coughing shortly after. My partner started to feel unwell on 20th June and he was admitted to A&E on 21st June with breathing difficulties and put on a nebuliser to help him breathe (he is asthmatic). Back then I never even thought it was the mattress due to the ‘hypoallergenic’ claim. I now have a different view on this, hence the review. After Simba arrived, he was unwell for weeks with his asthma and prescribed steroids to help him breathe. The smell from the mattress was rancid and lasted a long time. Simba claims that its products are hypoallergenic. However, how does Simba explain my partner being admitted to A&E 2 days after sleeping on the Simba mattress? There is no such thing as a coincidence. Pillow: A few days after my partner used the Simba pillow, his GP confirmed that the muscles in his neck were tense. He was referred to a physiotherapist and went back to his old pillow. The pillow is just overpriced nonsense. Mattress Protector I received the ‘free’ mattress protector and to put it bluntly, I find this mattress protector to be pointless. The installation was simple. However, when you put the bottom sheet on, you must stretch the protector simultaneously, which is a challenge. In terms of pricing, the sheer pointlessness of this mattress protector makes the cost unjustifiable if bought separately. There is no such thing as ‘free’. Recent experience: I have recently purchased a new amazing reinforced heavy-duty divan bed base from a third-party company and this has opened my eyes about the Simba products. This has made my Simba mattress the most comfortable mattress I have ever slept on. However, I have learned that to have an amazing comfortable bed, the bed base is just as important as the mattress, if not more important. The Simba mattress was uncomfortable on my old bed base to the point where I almost asked for a refund. Lastly, the price point of the Simba mattress is high compared to other similar options on the market. While I understand that quality comes at a cost, I'm not convinced that the higher price is justified by the overall poor experience I have with this mattress and pillow. My bed now is the most comfortable bed I have ever slept on and I struggle to get out of it as it has a habit of hugging me in the morning! However, 90% of the credit goes to the new bed base rather than the overpriced Simba mattress. I am leaving a 1-star review as the Simba mattress put my partner in hospital as it triggered his asthma and I do not recommend and I will never buy from them again. If you are asthmatic, I would think twice about ordering from Simba, regardless of what they claim about the hypoallergenic hype. When the product is unrolled the smell is toxic and rancid, so how is this hypoallergenic? My partner's asthma is now stable after the smell went about after 1 month and he has been fine since. I don’t want to return my mattress but a refund is justified for the hassle you have caused to my partner's health. Depending on the response from Simba will determine whether or not I make a Section 75 chargeback, and/or legal action.
