No dips. Snug and warm.

Very quick turn around and comfy mattress

I can't believe how comfortable it is. My wife and I are delighted.

After years of back and hip pain as well as constant partner disturbances, I'm finally sleeping through the night and waking up feeling refreshed! Love love love!

I am loving the SD Mach II mattress. My previous mattress had lost it's support and had sagged, contributing to a sore back and hip. The SD is so comfortable and supportive that my aches are gone and I'll sleeping soundly and waking up properly refreshed 😌 highly recommend

We got both the mattress and bed frame and chose something we really liked. It wasn't cheap, but it looks and feels worth the money. My only issue, which doesn’t affect the rating because it’s excellent, is that we find it hard to make the bed—especially fitting the sheets under the mattress. It's so heavy and well-positioned that it doesn’t budge a millimeter. You might laugh, but it’s challenging to tuck the sheets under! Perhaps there’s a technique to be discovered. Overall, it’s a great purchase and the best bed I've bought in 30+ years. It feels like it’ll last a lifetime.

After switching to sleeping duck I’m not waking up as sore as I used to, being able to customise the mattress is such a game changer

I was a bit sceptical about purchasing a sleeping duck but after receiving and sleeping on a sleeping duck I would never go back to a traditional mattress. It is the most comfortable mattress and I have never felt so well supported. Highly recommend

I wish I had made this purchase a long time ago. Have never had a mattress this comfortable.

Definitely built to a standard, bed base, including the packaging and assembly. went with Firm/medium combo which works well. for the lighter wife. initially firm seemed quite firm first night however very quickly proved the right choice. Stiff and tired back pain (builder) has been relieved through the night now wake up pain free to start the day. The PILLOWS, don't quite fit the pillow cases, and seem a little thin and undersized at first but are brilliant, in support and comfort and proved compatible with CPAP mask. they match the bed perfectly. The wife also feels the benefits. Standard height legs are more than high enough, Forgot the price now rewards are validated.
