Amazing customer experience and mattress is exactly what I needed

My partner and I have different mattress firmness preferences. I really like the extra firm insert while my partner prefers the medium insert on their side. I love how you can customise SD to suite your needs. I had hip pain develop on our old mattress if I slept for more than 4 hours. The SD mattress has allowed me to get much better sleep and now I can wake up fresh the next morning without pain. The mattress is very heavy, so get some help with the rotation of it.

Very pleased with sleep comfort now

Love my mattress, it does sleep a little hot

Very very happy with the mattress and pillows however the white bedding is completely see through. You can see the entire pattern of the mattress through the bedding. Disappointing for the price.

I'm a Parkinson's Disease patient. Quite often waking up in the morning with hip pain. I thought it was my old mattress but after changing to MACH II extra firm, occasionally the hip pain is still there in the morning. It may not be the mattress after all. Nevertheless, the MACH II is comfortable and service is good.

A new mattress is a big decision. However, all the positive reviews and knowing the mattress can be customised with ease made the decision easy. The mattress was a huge step up in comfort from day one although, I had to settle in and my body took a few weeks to adjust. However, after a few weeks I started to notice changes, changes I certainly didn't know a new mattress could do to the body, but these are the things a good night's sleep do. My wife felt her side was to soft, so she wanted to make it firmer. I simply reached out to SD and they send out a firm adjust for her and now she's also very happy. Will definitely recommend this product 👌

all good with default medium firmness but wife thinks the firm may be more suitable for her, will have to check.

I look forward to jumping into bed every night and don’t want to get out in the morning. It really is such a great mattress. It’s so comfortable.
