The Best Mattress Buying Guide: Eve vs Casper vs Simba

Image source:

We all need 8 hours of sleep but which mattress can help you nod off easily? Eve, Casper or Simba? We investigate.

Everyone needs sleep (apart from Thái Ngọc, a Vietnamese insomniac who claims to have not slept for over 40 years). Thankfully he’s in the minority, with most of us needing a good 8 hours.

However, in the last few years the average Briton has been sleeping for less – just 6 hours 35 minutes to be precise, so we need to make those hours count.

Mattress makers no doubt feel the same and several new brands have sprung up, all claiming to have a one mattress fits all approach. But can buying a new mattress really be that simple?

Delivering a Casper mattress in London
Mattresses are tightly packaged so they can be delivered easily

There are lots of online mattress brands out there, Hyde & Sleep, Otty, DuraTribe, Snug – we could go on. But three are leading the way, so we’ve delved a little deeper into the Eve, Simba and Casper offering.

These mattresses aren’t expensive when you compare their prices to more traditional brands like Tempur and Silentnight, and you can pick up a standard memory foam mattress online for around the £100 mark – so what is it that differentiates this new generation of mattresses from the pack?

With space at a premium, the fact they arrive vacuum packed and rolled up in a box is not to be sniffed at – although there is the chemical smell you have to deal with for a day or so. And have you ever tried lugging an orthopaedic mattress up two flights of stairs? (Hint: It’s not easy).

They all have an attractive 100 night trial offer with free delivery and returns, which can make clicking that buy button a bit easier, as there are still people out there that like to try before they buy.

Casper, maybe less well known here right now, has been gaining popularity in the US since 2014. They currently have a pop up in Covent Garden where you can try out their mattress and Eve has a pop up in Debenhams on Oxford Steet.

Although if you’re not living in or near London that’s not much use to you. Simba is probably the easiest to access with a demo mattress in most John Lewis stores.

But what it really boils down to is if your sleep is improved.

Casper, Simba and Eve all have a number of reviews and testimonials on their websites, but what about something a bit more impartial? See our checklist below to easily compare the brands.
