We tried a sleep number bed about a year ago, due to my stiffness and pain in almost every joint when waking up. I had high hopes for it, but it didn't help at all, mostly because the two sides of the bed weren't truly independant; it went from soft to firm depending on whether my husband was in bed on his side or not. Even the dog climbing up on the bed changed the firmness of my side! I got so tired of waking up in pain I was in tears, and desperately wanted to get a temperpedic bed instead. Unfortunately, we couldn't afford one, especially after having bought the sleep number bed less than a year ago. So we got this 4" foam topper, cranked the pressure on both sides of the sleep number mattress (to make an even, equally firm surface) and put the topper on it. It's been a miracle for me. I don't wake up in tears, I don't wake up in the middle of the night at all anymore. No more Advil breakfasts either! And best of all it cost a fraction of what a temperpedic bed costs.

Don't get me wrong, if I had the $$ the sleep number bed would be out the door and I'd get a new memory foam bed altogether; but for now even this is soooo much better. For the first time in years I'm sleeping good, and waking up pain-free. And happier too.

I have purchased many matress pads and toppers over the years and this is the best yet. It is comparable in comfort to one of the heavy (and much more expensive) memory foam ones, but is very lightweight and easy for me to manage by myself, even with arthritic hands. Money is tight and I hesitated to get this right now, but it was worth every penny. No backache and no neck pain from the very first morning. I am over 60 and not such a lightweight myself and would highly recommend the 4 inch topper. I shopped around and this was a good price (about $125 for a twin size). It arrived quickly and I was able to sleep on it the same day it arrived - no time was needed for the foam to relax after unrolling it and no smell or odor at all like some of these toppers seem to have for the first while. It really is quite cool to sleep on, but not cold, so don't let that discourage you if you are considering the Sleep Studio Ventilated Topper. I couldn't be happier with this product and if anything ever happens to it I will rush to replace it with another just like it!

Just to update, it is now almost 3 years of nightly wear and still wonderful and like brand new. Can't say enough good things about this still in July 2013.

This product was a great disappointment when it arrived because I expected a memory foam topper. This mattress pad is simple foam pad, as in the material an egg crate is made of. It is very soft and very thick but not what was advertised. Memory foam molds to your body which is why in the description for all memory foam pads it takes around 48 hours for the pad to regain shape. I have owned one before and found it helped reinvigorate a poor mattress that caused me back pain because memory foam will support your body shape. As a foam pad will not. This pad does not mold to your body shape so much as it sinks in towards your pressure points without supporting other parts of your body. A good way to tell the difference is if you sit on the pad does the pad curve towards you or does simply the part you are sitting upon indent. If the entire pad curves toward you, as this one does, it is not made of memory foam. This product is not labeled correctly and considering the size and difficulty returns are I would hope that amazon.com would review the descriptor and change this. If you have a firm supportive mattress or bed, this topper would be excellent way to add significant softness to your mattress. However if you are looking for memory foam for any real reason, this product is distinctly not memory foam.

I've had Fibromyalgia for 22 years. Sleeping is my biggest issue and I usually end up on the couch. Well, the couch is wearing down so I decided to try this on our bed. I put it on top of our Select Comfort bed which was another expensive failure.

While I believe the product is good, it's comfy, doesn't smell bad and seems to do what it says but it didn't seem to help with my Fibromyalgia at all. My hips don't hurt as bad but my neck and shoulders hurt horribly. I have to turn literally every 2-5 minutes the pain is so bad. I tried a new pillow with no luck so I'm sure it's just me.

Like I said the product seems good but if you have Fibromyalgia it may or may not work for you.

This enhancer is a great product except for the fact that it takes time to adjust to sleeping on it. The foam is quite stiff when you first lay on it. It than begins to form to your body and feels quite nice. However, when you move you have to hold your position the way you want it while the foam rebounds and takes your new position. As for the ventilation, it works very well. You remain at a normal temp all night and not over heating at night with the sweats like non ventilated memory foam mattresses do. Overall a great product, but a learning curve is included.

You want a soft surface to lay on? You want to sink into the comfort? Man you could put this on concrete and it would still feel great. However, the foam this is made of has a tendency to tear easily. That's a problem when this mattress is so heavy. Make sure you have two people to move this, otherwise, you're asking for irregular support while moving and inadvertently tearing the foam.
