Excelente producto
La verdad esperaba que fuera un producto medianamente bueno pero mi sorpresa fué otra, es un producto bastante bueno, compré uno de una media de anchura menor y se estiró hasta encajar bastante bien, su cierre es muy bueno y sus materiales también, lo único que no me gustó fué que dejó aire encerrado dentro y se hace una burbuja de aire al acostarse pero es un detalle menor y solucionable. Muy bien producto.

Best size to buy for a 10" thick Tulo mattress
I put this encasement on a new Tulo full size 10" thick mattress. I compared this encasement with one from Linenspa, Utopia Bedding and Saferest. Actually I looked at many more, but narrowed it down to these 4. Here is why I chose the Sleep Defense System:1. Only one that was really properly lab tested and hospital grade.2. Polyester soft knit fabric. Linenspa has polyester also, but my friend bought one and it slips around a lot and is noisy when you sleep on it. Utopia Bedding one is PVC which is very slippery and noisy. Saferest is cotton terry and very soft and probably not noisy, but their price was the highest of all 4 and it just did not seem worth $50.3. The bug flap and zipper lock. I felt that the Sleep Defense encasement had the best system for keeping out bed bugs.4. Reviewers said the encasement was breathable and they did not get hot at night. I find this to be true.5. Size and Fit. These encasements are noisy if they are too big and they slip around. Plus they are uncomfortable as well. I bought the 9" to 11" Low Profile in the full size and the fit is perfect for my 19" mattress. I have nothing underneath it like some people do. It slipped on very easily and it does not move around and there is no excess that I need to tuck in somewhere.6. Of the 4 brands I compared, Sleep Defense had the most reviews, 5,193 at the time and the highest rating of 4.6.If that many people love it, I figured I could not go wrong.I was very happy from the minute the cover arrived and having slept on it for a little over a week I am still very happy with the product. I would highly recommend this product to anyone needing a high quality, multi-functional and reasonably priced encasement.
