## Description

Review: I got this for my daughter as her previous mattress was just memory foam and rather thin, therefore quite uncomfortable on her new bed frame. When this mattress arrived in its box I took it out and left it for 48 hours, after which it was fully decompressed and seemed to be pretty good. For me personally I think it’s way too springy and soft, and doesn’t offer enough support for my back which needs a fairly firm mattress. However, my daughter on the other hand loves it. She says it’s super comfy and she has slept better since getting this than she has in a very long time. I’ve also noticed that it’s stopped her wriggling so much in bed, leading me to conclude that this was due to her previous mattress not being comfortable enough for her. It’s a good depth for the price too. Over all, for a budget online mattress, this is pretty good. The reason I’ve dropped it a star over all and for comfort is that it’s not for me, and softness got 5 stars because it is very soft. Like I said though, it’s not for me and certainly not for everyone. If you prefer a firmer mattress this isn’t for you, if you like soft and springy then try this. Ultimately it’s personal preference, so I’ve split the difference in star ratings and tried to give you a good overview from 2 view points.
Review: The mattress is good and worth the price. However, delivery was fulfilled by desertcart and did not meet the promised next-day timeframe, arriving two days late. This was disappointing.

### ⭐⭐⭐ Review
*by I***R on 23 March 2024*

I bought this mattress back in June 2023 and held off reviewing it until I had a good feel of it. The mattress is surprisingly comfortable for the price - let’s be honest, it’s not hotel quality, but it is quite firm and supports my back pretty well. The biggest issue is quality; first of all, it does not look as good as in pictures - it has a much cheaper look when it arrives, and the material is paper thin - it seems a bit like a cloth rather than fabric. This leads me to my next point: after a couple of months, the mattress started developing cracks near the edge stitching (see pictures). I am not expecting it to last more than one more year. Also, shipping was delayed by a couple of days, and as we were moving into a completely new property, we had to spend a couple of nights on the sofa.
