I purchased the mattress protector for my Daughter. She says it has a nice feel to the material and fitted her King bed perfectly. However she did find it easier to put it onto the mattress when she had an extra pair of hands to help her. She very much likes the look of it and is very happy with my purchase.

Absolutely fantastic.True to size & easy to put on as the zips open the cover right up.I was able to put this on my mattress by myself. If the mattress is heavy, it may take 2 people.Great for asthma sufferers.It's really quiet & doesn't disturb sleep at all. I also use another regular protector over the top which is changed and cleaned every week.It's recommended to wash this fully enclosed protector every season (every 3 months).If you're concerned about dust mites, mould or bacteria getting into your mattress then use one of these.Latex mattresses can also grow mould. It's not advertised by sellers but I've recently discovered that it's a very real, serious problem. This mattress protector stops that from happening. It's waterproof so no moisture ... MoreAbsolutely fantastic.True to size & easy to put on as the zips open the cover right up.I was able to put this on my mattress by myself.

These are the best mattress protectors for anyone who suffers from allergies. They fully encase the mattress & prevent mould/dust mites & other allergens from building up in your mattress. I haven’t coughed or sneezed throughout the night since I bought this mattress protector - 100% recommend!

Mattress protected?
31 March 2023

Easy to wash and fit, not very thick not hot or bulky, zips are very long for ease of use and then a seal included. Guess it does the dust mite, bed bug thing but I haven’t had course to check this, let’s hope I don’t, but looks like it will work. Haven’t checked the waterproof attributes, I bought this as my 2 yo granddaughter slept in our bed! But should be good for spills and to prevent staining on our expensive mattress. This was on special so cheapest at Myer.

Mattress protector
21 April 2022

I didn’t realise that it was a fully encased/enclosed mattress protector. It’s hard core nothing will get in there once it’s wrapped in this thing. Actually I was after a normal. It’s pretty good though. You have to literally lift the whole mattress off the bed to fit it in. Once it’s in though I’d say it’s a true mattress protector, top, bottom & sides.

Says What it Does.
11 February 2023

I bought this online, so I think I should have bought the double not the queen, but in saying that, I think it’s a great product.What I like is that it fully encases the mattress, and although I mainly want to protect the mattress from possible soiling from people sleeping on it, being encased in the cover protects the mattress from bugs, etc., but it’s still very breathable.I thought the instructions to put the cover on didn’t make a whole lot of sense even though there were diagrams to assist.I bought the cover for our spare bed which is a pull out couch with a thinner mattress so I found it easy to get on, but as much as I would perhaps like it for our king size bed, I think it would be difficult to get on (and then off to wash regularly).Generally I think ... MoreI bought this online, so I think I should have bought the double not the queen, but in saying that, I think it’s a great product.What I like is that it fully encases the mattress, and although I mainly want to protect the mattress from possible soiling from people sleeping on it, being encased in the cover protects the mattress from bugs, etc., but it’s still very breathable.I thought the instructions to put the cover on didn’t make a whole lot of sense even though there were diagrams to assist.I bought the cover for our spare bed which is a pull out couch with a thinner mattress so I found it easy to get on, but as much as I would perhaps like it for our king size bed, I think it would be difficult to get on (and then off to wash regularly).Generally I think the product does what it’s supposed to and offers good value for money.

Sentinel Fully Encased Waterproof Mattress Protect
23 July 2022

Excellent quality fabric that doesn’t make that plastic noise you get with others and I am so impressed because the entire mattress is covered on the top and underneath and it is fully protected. It’s like a mattress bag with a smooth metal zipper all the way around so the mattress is entirely enclosed within the protector. Washes really well and dries quickly and easy to attach and remove from the bed. You effectively have two protectors because you can use both the top side and the bottom side of the bag. Both sides are identical I am just saying that you have that option. For all these reasons Highly recommend !!

The best protection for your mattress!
1 November 2022

Excellent mattress encapsulator/protector! I've been using this on my older kids mattresses for 2 years and when I take them off to launder the mattress looks brand new. The fabric is soft and smooth and doesn't feel sweaty or synthetic at all (I was worried about this given it is waterproof). A fitted sheet sits well on top without sliding off. Recently purchased for my own King size bed and was surprisingly easy to slip on without having to lift up the whole (very heavy) mattress.. I managed to do it on my own in just a couple of minutes. The king size does take a bit of time to dry and can be fiddly to turn inside out and then back again when wet, but we only do this every couple months. Overall this is very worthwhile; you will get years more out of your ... MoreExcellent mattress encapsulator/protector!

Overall this is very worthwhile; you will get years more out of your mattress and rest easy knowing it's bug proof too. The only downside is it is not organic/natural, but with 4 small kids in the house I wanted something fully sealed and waterproof; if that is what you are after then this is simply excellent. (Bear in mind, given it is a full wrap, for a toddler I would add a mattress protector on top that can be more easily slipped off in the middle of the night in case of an accident.)

Thoughtfully designed product
13 October 2022

Perfect so far. Haven't had any major spills yet though so it's hard to tell how waterproof it really is. It doesn't make crinkly noises and you can't even tell it's there. Even comes with a little zip tie to ensure the zippers don't separate and open while you toss and turn!

Worth the money
28 October 2019

This Is a fully enclosed bed protector. It's not just your regular one that you put on the bed. This one goes over the entire mattress. I had to lift up the mattress from the base and lay the protector down then put the mattress on top and zip the protector up. Just want to put that out there so you know what you're getting.The idea around this is to fully protect your mattress. If you're like me and have an expensive one then this is worth the investment. It's fully waterproof and quality design and made. I have used this brand for years on all the family beds. They have not failed.The only negative although some would not consider this a negative , the protector is slightly big for the bed. I got a king size for a king bed but it doesn't wrap really tightly ... MoreThis Is a fully enclosed bed protector. It's not just your regular one that you put on the bed.
