I purchased 2 Intex Pillow Rest Twin Beds due to the size specifications of 40 X 80 X 18 1/2". They were to be used by my >6 ft. tall family members when visiting. I was extremely disappointed when we inflated the 1st bed - which BARELY measured 32 X 70 X 16. I sent a letter to the supplier, CMS WorldWide Sales, explaining my dissatisfaction & was told to send pictures & measurements (which I did) and they would [quote]..."Once you had provided us the information we had requested, we will be glad to forward you the return shipping labels."This was months ago, and to date I still have 2 Intex Pillow Rest Beds (the 2nd box was never even opened!) that are no where near the specs stated on the packaging.I will NEVER order anything from the CMS WorldWide Sales supplier again.
Output:
Negative
