    • So soft and comfortable
      Verified Purchase

      Honestly, 4 inches was probably a bit of over kill. But this is like sleeping in a delightful little cocoon. It is perforated, so what I actually did was put a heated mattress pad underneath it which means I am not bothered by the wires in the mattress pad and the heat is more diffuse. Based on the amount of heat transfer, I would imagine the perforations are also good for sleeping cooler in the summer.

This thing is like a piece of hard foam and is very uncomfortable! I'm working with OS now to see if this was the wrong one shipped??

    • Not comfortable

      I bought this based on reviews from outside websites, and it is a huge disappointment. My firm mattress feels even firmer and I feel very little support from the topper. Sleeping on my side, there's pressure on my hips and shoulders and when on my back, the middle of my back is unsupported due to give in the foam. I was seeking a balance between a firm mattress and toppers that are so soft you sink into them. This is not it! Overstock has a terrible return policy as well, so I will be buying a future topper from ***. It's 50-50 on whether something will work out after opening it and to be stuck with it, has finally made me give up on Overstock for good.

      Bought the 14" mattress and decided to buy the topper as mattress it covered was not old, just not comfortable...revitalized the comfort of the spare room bed...guests stayed and said they had the best night's sleep in years...and ordered one for themselves! Price great, comfort fantastic!

      I needed to purchase a 4" foam pad for my daughter's college apartment. It had to be exactly like the one she has at home which I purchased about four years ago and didn't remember from where! I did a lot of searching and Overstock had the best price for the best quality. This particular pad had minimum smell, gone in about 4 hours and it also had ventilation holes which was a must. Very pleased with this purchase and would definitely buy again!

      Very comfortable. I have problems with my back, shoulders & neck when sleeping. Had this for 3 days and what an improvement. We've had our bed for 2 years and we just were not sleeping well until we purchased this memory foam. Well worth the money. Density is very important when deciding on a memory foam.

    Questions & Answers

    • Q:

      "Does this topper have an odor? I'm really sensitive to chemical smells, and after reading about the impossiblity of re-packing these toppers to return them, am concerned about being stuck with something that I'm unable to sleep on. Many thanks for any help!"

      • A:

        The instructions say to lay it out for 48 hours to let it reform from shipping. At that point it did have a slight odor. We layed it out in the spare bedroom for the 48 hours. It reformed from shipping and the odor was gone.

      • A:

        Thanks SO much for your reply, ozarkglen!!! Very helpful. I don't mind being patient and letting it air, as long as the odor finally does dissipate! :) Many thanks!
