Should I buy a Hyde & Sleep Mattress?

The Hyde & Sleep mattresses are popular with consumers and receive great feedback across their models. So, what kind of sleeper do the Hyde & Sleep mattresses suit? The mattresses do have a lot more sinkage than some other bed in a box brands, meaning that you do feel fairly ‘encased’ in bed. Of course, some people will prefer this! The mattresses are also well suited to back sleepers, although side sleepers may find the sinkage doesn’t provide too much support for the hips.

One of the best things about the Hyde & Sleep range is that you can choose the firmness level. The hybrid memory foam and spring mattresses come in medium, firm and extra firm options, whilst the all foam mattresses come in firm and extra firm. This means sleepers can choose the comfort level that best suits them. The hybrid versions are firmer overall than the foam options.

As with all mattresses, the Hyde & Sleep options won’t suit everyone. The mattresses do not provide as much edge support as many other brands and the aforementioned sinkage won’t be to everyone’s liking. In addition, sleepers do say that the mattresses sleep hotter than other bed in a box brands.

With much to recommend them, the Hyde & Sleep mattresses are great contenders for those in the market for a new mattress. Our review should help you decide if it’s the mattress in a box for you.

T3 Magazine

I brought this for the guest bedroom, but having slept on the mattress several times, I have moved it onto the main bed. It's really supportive and my back has been much improved since buying the mattress. (July 2020)

Hyde & Sleep Customer

Purchased this mattress to help with restless sleeping and waking up aching, I was not disappointed. From the first night what a difference, I now enjoy going to bed and getting comfy almost immediately. Highly recommended and a dream to sleep on. (May 2020)

Hyde & Sleep Customer

First time we have owned a memory foam mattress and have not been disappointed. Was worried at first with how firm the mattress was to touch as it feels like a brick wall, but when I laid down on the mattress, it was like laying on a cloud. The mattress is extremely comfortable and I have had the best night’s sleep ever since. (March 2020)

Hyde & Sleep Customer

I bought this mattress at the beginning of the year as I have struggled for a long time with back issues due to my height. This extra firm mattress gives me much more support and I find that my sleep has improved greatly. I also ache less in the mornings now which is really appreciated. (February 2020)

Hyde & Sleep Customer

Took delivery of this mattress about 3 weeks ago and I'm already sleeping better! Offers great support to my back and has made it so I sleep through the night without waking up with an aching back in the morning! (December 2019)

Hyde & Sleep Customer

We bought this mattress about a month ago and it has been excellent. We both suffer from back pain and are now able to wake up pain-free since using this mattress. We also don't wake each other up when one of us moves around, as the mattress doesn't react to the other side dipping. Fantastic mattress - really worth the money. (March 2019)

Hyde & Sleep Customer

Great mattress and super supportive. We were surprised at how relatively lightweight it is compared to our older bulky mattress, so it was really easy to move about. For the quality, the price is great too - we'd tried others which were around £600-700 more expensive and so glad we chose this one in the end. Looking forward to plenty more good nights' sleep! (January 2019)
