Extra thick egg crate

Will be evaluating its effectiveness on healing time of existing decubs

Pros:Availability in 4inch thickness allows for easier transfers making bed and chair height equal

Cons:Would like to see them come with a water proof cover that still allows the flexibility and lack of heat. Just a thought for the R&D folks

Overall: Yes, I would recommend this product.

Too soft for me. Cannot use this item as it offers no support.

The pad was exactly as described. But when I put it on my very firm, supportive bed, it took away all the support as it was so soft and bendable. I wondered if the less thick product would have worked out better for me, but since it cannot be returned, I will not try it.

Pros:quick delivery, quality product

Cons:too soft

Overall: No, I would not recommend this product.

Solution to my problem.

Caregiver in 24/7 home. Guest bed shared by all night caregivers. I found the full size mattress very uncomfortable, so I purchased this single foam for myself. I bought a single fitted bottom sheet and it's a perfect solution. I can easily roll it up and store out of the way, when I am not working. This has solved my personal problem without affecting other caregivers who use the same bed.

Pros:Soft, very comfortable. Easy to roll up and store. Can get it out easily when I work and it's the perfect solution to the uncomfortable bed problem for me, without affecting other caregivers.

Cons:Sinks a little in the center when I am lying on it, just where my bottom is. Wish it were a littel more sturdy/firm. Pops right back up when I get up.

Overall: Yes, I would recommend this product.

Just what our bed needed

Got this for our guest bed, which was extra firm and uncomfortable. Our guests love it and think the bed is very comfortable to sleep in.

Pros:Makes a firm mattress very comfortable.

Cons:Makes the bed so high, it's just a little awkward for short people to get in and out of it.

Overall: Yes, I would recommend this product.

Highly recommend this product!

Outstanding product, particularly when compared to similar product from other companies

Pros:Unlike other pads, this one did not come tightly wound up & bound in plastic; it was extremely easy to put on the bed and had no plastic smell!

Cons:shipping box is bulky but this was minor, and was actually a help in keeping pad from being too tightly bound up.

Overall: Yes, I would recommend this product.

I am impressed with this product.

This was a replacement for an egg crate I had purchased many years ago. I needed 75 x 75 but was told it would be 74 x 77. Was surprised that it turned out to be almost the same size I had hoped.

Pros:Very comfortable.

Overall: Yes, I would recommend this product.

Quick delivery, exactly as described, our bed is so much more comfortable.

Even though my husband and I are not elderly, we both have trouble sleeping. No matter how "soft" the mattress I was always uncomfortable. The eggcrate mattress topper has solved that problem and I now feel comfortable and we both sleep more soundly.

Pros:Nice cushioning.

Cons:Takes a few nights to get used to the ridges.

Overall: Yes, I would recommend this product.

mattress pad

Arrived very fast in great condition. Has made a world of difference on our bed!!

Exactly what we were looking for

My spouse & I (both past 60) have started having pain in our hips, shoulders, low back, etc. Our mattress is in excellent condition but was beginning to feel like concrete. We wanted a foam mattress pad for comfort but did not like the expensive, heavy, flat memory foam pads. This 4 inch egg shell topper is exactly as advertised and has been a great sleeping aid. It is not heavy and is so easy to handle that one person can move it. It does not "sleep hot" and does not collapse around you like a feather bed. It provides enough cushion to relieve all the pressure points. We would recommend it to anyone with similar problems regardless of age.
